Measure your gas port, check your gas tube protrusion into the upper receiver, list your barrel specs, and fully inspect and report on your recoil system - receiver extension INTERNAL DEPTH INTO THE TUBE, buffer length, buffer weight, recoil spring relaxed length, wire diameter, coil count... Based on that information, we can tell you if the gun is gonna run, or need work. Right away. All that stuff is fully covered in the "Waterboarding Thread" - it's right here: By the way - welcome aboard. Don't take this as discouragement. Details are necessary to determine if a build will function - from one's written words over the internet. Don't guess, don't assume that the manufacturer tells you a spec - measure it. Determine it, and report it. Your gun will run, if it fits the specific criteria for a running gun. Or it won't run, if it doesn't fit that criteria. We can make it run. With information.

Hey, Joe-Bama, here's what I hear that Trump had to take down. Brace yourself for it, you'll need to eat it, too...

I have a vested interest in how this turns out, specifically right now. It's not legal, directly after West Virginia Vs. EPA, Bruen, 5th Circuit Court against bump stocks. But they felt they had enough balls to do it anyway, and went with it. Rolled that dice. BATFE needs wrecked by the court decision that WILL come against them. And it needs to happen fast. They need put in their place once and for all, and that's already been done by legal precedent - Jurisprudence - from these prior decided cases. Once this one happens, I think the FRT triggers is gonna get wrecked, too. You're an agency that enforces passed laws. You don't get to "invent" laws. We have recent Supreme Court cases that define that, directly. You don't get to "change definitions" and "rewrite laws" and "modify definitions" on your own - that's for Congress, and Congress only. Period, full stop. No other argument matters. Get ready to eat a big dick, BATFE, over this one. You didn't step on your dick with golf cleats here - you JUMPED on it. Embrace the Suck, when you get shut out over this idiotic direction that you've taken. Oh, Biden - you can suck it, too. Trump had to eat that dick, recently, on what he did for bump stocks - your turn, bro... You though Corn Pop was a Bad Dude. The Supremes are gonna hand you your ass on this one... Based on precedent... RECENT precedent...

FWIW, everything I shoot is handloads, tailored to the gun, for what it's meant for.

MAN!!! You've been gone for WAY TOO LONG!!! Welcome back around, Ed! First, what kind of matches are you shooting - that's gonna determine where you go on the ammo selection. That one thing. Describe the matches that you're shooting. I shoot an Accurized AR Match monthly. All gas guns, only. Nothing shorter than 200, precision targets (small targets) at the shorter ranges, and it goes out to usually 660 yards, full sized IPSC plates or 18" diameter targets out there. We had one at 710 yards, one time in the last 1.5 years. I usually shoot 5.56 on these, but I've shot the 6 ARC once, .260 Rem a couple times, etc. The 5.56 can handle this match, so that's what I've fallen to, generally. It's usually the Mk12 Mod 1, but a couple months ago, I switched it up to the 16" 5.56 precision gun, and it did well. In the future, it'll probably be the 12.5" Grendel that makes it out there. It's all in making it harder on yourself, and stretching the gun to it's limits. Describe the match that you'll be shooting, man - that's gonna make ammo selection easier to recommend.

There's alot of PSA information up here, and even a specific section for all of it. The problems with their Large-Frame guns are prolific. So are the fixes. This seems like a short chamber - and the only fix for that is having a gunsmith ream the chamber deeper. You check this gun with any headspace gauges - the Go and No-Go gauges from any of the gauge manufacturers? What brand did you use? Different barrel manufacturers specify which gauges they use when chambering barrels, so PSA should be able to tell you the brand of gauges THEY use when chambering barrels. DC Machine is the barrel manufacturer that PSA bought several years ago, do DC Machine makes all the PSA barrels on their house-produced guns. Call PSA, and call DC Machine, ask that question. If you didn't check the headspace, don't even bother with the call. It won't help, and you'll get a run-around from both companies. This doesn't surprise me, at all, from them. Yep, that's a short chamber. That barrel wasn't made right. That's probably not gonna happen, unless you buy a different gun that works, from the factory. Aside from the short chamber that you seem to have, there's other things you'll need to fix on that PSA gun. It's all detailed out in the PSA Section on that. We've solved everything that they've done, over time, and figured the gun out in order to make it run. Short chamber is not on the list, though.

I haven't read this long thread of yours yet. This is your first post here, so very first, go rip you up some Intro Section, and tell us about yourself. Here's the Intro Section - I'll link it so it's easy. https://forum.308ar.com/forum/22-introductions/ Just go tear that shiit up, and tell us about yourself. That's step #1. Second, you need to read the Waterboarding thread, and comply with it's requests. I'm not even reading about this gun of yours until I have all the full details on it - ALL the details. Here's the Waterboarding Thread, linked for your convenience: Blow those 2 out, read them, soak it all in, understand it - and get back in here and tell us what your gun is doing. I'm not doing anymore of this waterboarding, after that last guy. Comply. We'll fix your gun. Don't comply, make it difficult - pansy around with details here and there - I'm not reading, not helping. Give exactly 2 shiits about your problem. Sounds harsh, I get it. I'm here to gladly hand out free information and fix your gun. I'm not giving it out freely, without the details of your gun. All the details. You didn't fuk you, here - the last guy did. Done with the bullshiit, and you're the first dude after that asshat that happened to show up, and have issues. Comply with the requests, and the help will freely flow. Or... Do whatever... If you want your gun fixed, compliance with the requests is an easy thing to accomplish. Just do those 2 things.

That's the skeery part, right there, brother.

So, THIS heated up on Friday the 13th - and we're not talking about it. Bottom line in all this bullshiit comes back to 26" OAL. If it's 26" OAL, it "can't be concealed," according to LAWS ON THE BOOKS... so this is all moot. Here's some comments on this Hot Mess. Ian, at Forgotton Weapons is a Ninja. Mike Glover makes good points, and isn't happy: There's more that will come of this, and the bottom line is - West Virginia Vs. EPA, The Bruen case in NY, the recent 5th Circuit Court ruling on Bump Stocks... This will get DESTROYED in court. But will it happen within the magical 120-day timeline that BATFE has established?... Prepare to be Felons, men. It's a trap, man-made trap, by this current administration. That's the bottom line.

Holy shiit!

Nice work, man - well done.

NO!!!

I still want to set this one up badly. I'll smoke this one. Might not be 61.94, but nobody is gonna beat me when we do it.

This is why we do what we do, boys. Remember the Fast Rope pistol drill? We did that a few years ago - the fast rope is still in a corner of a bedroom on my house. Drag the 75ft Fast Rope back to the shooting position, it has 2 x 25lb kettlebells attached to the end of it - elevate heart rate before shooting the pistol course of fire... It's a fake way of getting that adrenaline dump, before you have to shoot the course of fire - simulates getting caught off guard, and the adrenaline dump you'll see... Only a few dudes wanted to do it, most bowed out, thought it was stupid. @Matt.Cross drug that fast rope back, with 50lbs hanging off the end of it - This is why, for what it's done. It isn't to test stength of a certain individual - it's to add artificial stress, to make you shoot your pistol better when you're at a point that you REALLY need to be able to shoot your pistol... Read this quote: How did you decide to incorporate some of the workouts and more unorthodox stuff into what you were doing? PM: When I was in special ops units, we did a lot of that. Once I got into the civilian world, I realized, that when I put up my very first YouTube video, I was stationary as well. I was doing the same thing everybody else was, you know, all the other YouTube gun nerds. I looked at that video and really that's not me. It kind of fell flat. So I thought, well, let's see how this plays. Let's start doing stuff that I did while I was in the unit. For instance running and gunning, pushing, pulling, sweating, getting that heart rate accelerated before you go into a hard course of fire. And the response spoke for itself. Guys were like, “Yes.” So I started pumping a bunch of those out, like over the top, ridiculous, climbing rope, pushing a truck videos. I was throwing sandbags, strong hand shots from 50 yards, jumping up into the back of my truck, balancing kettlebells overhead. They were like “shot impossible” stuff. And the results are because of the number of views I saw and the responses were mind-blowing. So I thought I needed to keep doing this because nobody else was. Now, it didn't take long before other guys started doing that too. They said, “Oh, man, this guy. I need to do this just crap too.” I also incorporate a lot of movement in my courses. Nothing brutal, because I always have a pretty broad and wide skill set disparity, physical disparity, and age disparity. So I'm careful. We don't drag kettlebells, climb ropes, and crap like that. But there's a lot of movement, a lot of kinetics, a lot of foot movement, a lot of dance steps because fighting is fighting. There's going to be movement, there's going to be kinetics. So that has to be incorporated into the training. And people freaking love it, they just love it. Well, you saw it on Sunday. All the movement stuff that we did. You won't see that kind of stuff on any other range unless people are copying what I'm doing Here's the whole article: https://www.thevetsproject.com/the-blog/sgm-pat-mcnamara-army-special-operations

That's 3 MOA ammo, at best, so don't feel bad. Not your handloads - that M80 ball stuff Until you get your handloads sorted out, but they're still 155gr pills going through a 1:10" twist barrel, that really wants to shoot 168~175gr projectiles. Those 155s aren't gonna be the ultimate projectile that you use to determine how accurate your gun really is. They're just not. They're too light. To determine how accurate your barrel really is, you need to feed it what it's meant for. You pick up some Federal Gold Medal Match 168s and 175s, shoot those - see how that barrel does. That's gonna tell you if you have an accurate gun or not. After that, and your mind is assured - work on your 155s and make them the best that you can make them.

Yes, it's a standard DPMS-based LR-308-patterned barrel. BA makes barrels that will mesh quite well in STAG Arms guns. Perfectly.

I think I heard that BA separated from Aero. Let me see if I can find public info on that. That's just what I heard, industry shiit. Nothing out there publicly. I'm not saying anything. Be reading for an industry announcement, though. Not saying any more on that subject.

Best user of a comparator gauge that I know of is @JBMatt - lets get him into this conversation and hear his info. He's the most meticulous person I've ever met, for brass prep, and making badass handloads. Bar none.

Getting it down to 5-10thou is pretty badass. Very well done. Half a thou. Nice. So, the No-Go gauge versus unfired is within 1 thou? Measure a fired case, see where that thing comes up in comparison. That's gonna tell your chamber, right there. It's not uncommon for competition bolt gun reloaders to only load/bump shoulders a couple thou, 0.002?~0.003" - for their competition brass reloading. Gas guns can have a shoulder difference 0.005", and that's not something that you'd look at as weird, or out of the ordinary. Check your shot brass, man, see where it falls.

At 1:13:53, he hits on something (paraphrasing), "Talk about fulfillment... The folks that I have developed a relationship with... because we'll do bi-annual meets... It's an extremely eclectic group, skills set are all OVER the map, ..." That's you fuqrs, to me... The personal shiit that he describes, before that point in the interview - That's life, and it sucks, - and it happens. So many parallels. Freaky.

Didn't realize this before - the origination - until I found this Pat Mac interview. It's a pretty great interview, and worth your almost-2hrs, when you have the time. Here's the vid description: Patrick McNamara spent 22 years in the United States Army in a myriad of special operations units. When he worked in the premier special missions unit, he became an impeccable marksman, shooting with accurate, lethal results and tactical effectiveness. While serving as his Unit's Marksmanship NCO, he developed his own marksmanship club with NRA, CMP, and USPSA affiliations. Mac ran monthly IPSC matches and ran semi annual military marksmanship championships to encourage marksmanship fundamentals and competitiveness throughout the Army. He retired from the Army's premier hostage rescue unit as a Sergeant Major and is the author of T.A.P.S. (Tactical Application of Practical Shooting) and Sentinel. Now, before we get to the video, here's how that statement above impacted me. Around 1999 or 2000, while assigned to 1st Special Force Group (Airborne) at Fort Lewis, WA... we received a HUGE influx of Delta guys into the unit, in senior leadership positions. It was wild, and it impacted everything we did in every way. Training changed, planning changed, operations changed - just due to the influence of these Senior Leaders. We started doing monthly shooting competitions, on our own range (Range 43) scross the street from the compound, on Fridays - once a month. You had to "donate" $3 to the unit FRG, and they had issued weapons out there, or you could draw your own guns from the Arms Room, walk across the street to the range, and participate. Looking back on it, it was more like 3-Gun type stuff, without shotguns. So 2-Gun? Sidearm, M4A1`. Different shooting positions, different targets at different distances with time limits and round hit limits on everything. They broke the results up in 2 categories, Top SF Shooter and Top Support Shooter. Winners names went on an engraved plate, that was attached to a giant trophy, that was placed in the Mess Hall. That first one, I won Top Support Shooter for the Group. My name is still on the first plate on that trophy, in the Mess Hall. Pissed alot of guys off, because I outshot alot of the SF shooters on that one, but that wasn't my category... There was alot of WTF after that first match, and it just made everyone work harder, try more, get better. At any rate, that changed how we trained on the range, in a very big way. We'd start training scenarios like that, all situational, par times, round limits, just to do better in the monthly shooting matches. Come to find out - this was all driven by Pat Mac when he was in Delta, and it was brought out to us at Ft Lewis by that massive influx of Delta dudes into the unit at that timeframe. And here we are - why I try to do what I do, with the annual shoots, with all of you... It comes around full circle, in the bigger picture... Here's the Pat Mac interview:

My opinion, which doesn't really matter. I think 18" barrels are the perfect length. It's the very best mix of precision capability, and maneuverability. It's easy to make a gun with an 18" barrel do whatever you need to do, in almost any situation or circumstance. To me, anything with an 18" barrel is the perfect AR gun, perfect precision gun. You don't need any more barrel than that, for whatever that cartridge you're shooting is capable of. If you can't make it perform, with an 18" barrel, you're not gonna get it to perform with a barrel that's longer, either. Now, I'm going to contradict everything I just stated, based on your conditions, desired goal, and shooting description. Do the 16" BA barrel. BA makes fantastic barrels, sub-MOA guarantee if you're using match ammo, and I can confirm that every barrel I've ever purchased from BA is certainly a sub-MOA barrel. More expensive barrels aren't gonna give you a huge leg-up over a BA barrel. ^^^ Based on that end statement that you started out with - excellent, by the way - the 18" barrel isn't going to give you an advantage over the 16" barrel, based on your desires for the gun. It just won't. It's simply more weight on the gun, and more importantly, swing weight of a longer barrel. Swing weight is a big deal, moreso than carry weight. I've run my 16" BA barrel out to 1k yards, when I feel like setting those targets up, but more routinely out to 850 yards, which I set up often. The 16" is more than capable for that distance, and it does it effortlessly. 1k is a different story for a 16", but it's possible, and repeatable, once you have the wind calls figured out that day. My vote, for your case - 16" BA Barrel. For what you want the gun to do for you, the 16" will easily handle that, plus more distance, if you want to. At that point, if you like distance, and have it to shoot, and you want the gun to do more for you - build another gun. Keep this one as your hunting gun out to 250, and target hitting out to 500... My $0.02...

That will help - you'll see better results on paper, when you're testing. .308 WIn doesn't need 0.5grain steps in load development - you'll miss something, steps in grain charge are way too large. You're only talking about 45-ish grains for case capacity. You go 0.5 grains on ar loads, you'll certainly miss something in the ladders/load charges, for accuracy. There's just not enough case capacity to support jumps that large, without missing a node in there, somewhere. For that reason, I run those big bastards 0.3, hit all the close ones where I didn't have pressure signs, then go back to 0.2 from there to finalize them. Never had to run a large frame, bigger case load down to 0.1 grains to find the perfect load for a gun that I have, or a load that I've developed for them. Again, I never put in the work that I did on the Mk262, going 0.1 off, just to find the perfect one. That worked, though. And that's a small frame gun, 5.56 case, 75gr projectile, and making that load was my nemesis. Beating that factory military load was my nemesis. That was my goal, and it was obsessive. I managed it, but it took years, years in projectiles, powder, primers, money, time, shooting, barrel life... It wasn't easy.

Here's some Jack Carr shiit, with Kyle Lamb on there in the interview - pretty damn good. At exactly 6:32 in this interview, you'll see some shiit come up. It's a BRCC coffee cup. They get into that real quick, and the hate that BRCC has seen, and thy dismiss it - pretty quick. BRCC ain't bad, no matter what you read here, or who hates them, or who's hating on them, when they're doing it. I'll stand behind that, no matter what gets posted about BRCC, Evan Hafer, or any or those guys. Fuk the haters. Because they're whiners.

The hard part here is - the recommendation was given. The gas port size was identified, way earlier. You didn't apply the recommandation, though you received the gas block a week ago, but you shot the gun today. You posted 3 hours ago that you shot the gun today. The hard part here is helping people. You advise, do what you can. Tell them what you think, based on years of experience, countless rounds down range, multiple calibers to fine tune over the years, and decades of gas-gun time behind the trigger. The money... just the money involved with doing this, well, since 1985 for me - back when I wasn't paying for it. I've been paying for it since 2007, though. The dedication to being able to fix one's gun problems - over the internet - has been fine-tuned here. We can do it. We've proved we can do it, and have the results to back it all up. It's just hard getting back in here today, reading your functional issues, and finding out that you didn't follow the recommendations previously. And, then, still try to diagnose the gun issue. It wasn't until I specifically asked you about the adjustable gas block, that you mentioned anything about not installing it. This, right here, is exactly why we have the Waterboarding thread in the first place. This one:
