It takes alot of rounds downrange, on the platform you're shooting. Caliber, too. Same platform, different calibers? Different training. Completely. Start from scratch, and spend a bunch of time, money, ammo - until you reach proficiency. Once you reach proficiency - you need to train to failure. Go, until you suck. Figure out why that happened... and fix it... I can perform intricate brain surgery with a .mil issued M4A1 and Mk 262 issued ammo. Aimpoint out front, lock on the PVS-14 on the back of the gun behind it when the sun's going down. I'll take a Mk12 any day over the M4. All day, every day.

My thoughts, exactly.

Need WAY MORE INFO FROM YOU on this thing. Making an Introduction doesn't hurt, either - so we can get an idea of who we're working with, and passing out free advice to. Here's the Introduction Section: https://forum.308ar.com/forum/22-introductions/ Here's the kind of details we're gonna need on the gun that you have/built/bought. Details are everything, and right now, we don't have much from you. Check this link out, look very directly at what it's specifying, and try to comply with the information as best you can...

I stuck through it -I'm a FIRM believer in the Barnes TSX projectiles, and their tipped varients, for the very reasons you've stated.

I'll leave that to Doc - he's the Pro at that...

That's why I described the above process...

I have been known to "thin a wrench down" on the grinder, to make it thinner, to handle these tasks. I don't care if it fuks up the wrench, just get another. Make it thin - put the sides in a grinder. Or get a cheap wrench and grind it down. Problem solved.

CLIFF!!! Good to see you, man! That's some fat cornfield-fed Ohio deer, right there, brother! Very well done. I miss Ohio deer. They're bigger there, than any other state. That's what I remember as a kid, anyway. 'UGE!!! Well done. How are the pups?

Yep, 0.090" is exactly where you want to be, provided that gas block journal diameter is 0.750". Standard gas block size. You can get by with 0.085" if that recoil system is right on the money, and the ammo is either great handloads, or Federal Gold Medal Match purchased ammo.

Funny you state it that way. Me and @JBMatt shoot a match each month, and the way he describes it is like that. Timer goes off, you go after it, it might be an 8rd stage or a 12 rd stage, and you clear it, maybe shot an extra - maybe hit everything single-shot per target and cleared it perfect. One rd per target. Matt calls that>>> "DUDE! You were shooting UNCONSCIOUS!" It was nothing but economy of motion, movement, targets hit - and zero thought going into it. Muscle-memory stage, right there. Smoke 'em. Never the same stages, but every once in awhile, the distances, target sizes and paint, the gun, the optic - all cooperate with what your head is trying to do, if it's even turned on...

You jackass...

What did you think of the two calibers, against each other? I know that .260 bang-flopped that deer... What's your impression of one versus other? You're the only guy I know that's taken a deer with each one...

It won't. You'll be fine. We see this all the time, and every single time from PSA. That 18" midlength barrel should have a 0.750" gas block journal diameter, and it SHOULD have a 0.085" gas port diameter to run properly. I'm willing to bet money your gas port diameter is 0.070" - and your gun is running because of the increased backpressure of the can on there. Just my $0.02.

16" midlength gas on a .308 with a 0.750" gas block journal will need a gas port diameter really close to 0.090". KAK usually gets the gas ports right, so I wouldn't worry about taking the gun apart to check it, if it's running. They're good for this stuff, that other companies ignore. Check the recoil spring in that thing. Details in wire diameter, coil count, relaxed length... If it's not very, very close to the specs on the Armalite EA-1095 spring, then just get rid of it. Use the EA-1095 or the Sprinco Red, and you'll be happier. It might charge easier, too. Look at that recoil spring first, in this situation.

Yep, I see someone breaking into your house as an ambush on you. You don't get to pick the time, place... you have to react to the act upon you. Most times that will be in the middle of the night, and you need to wake up and just go towards what's threatening you, inside your property. That same gun has a 45* ambi safety on it. Get it off, do what needs to be done on the trigger, easy to go back on with the trigger finger when it comes out of the trigger. If it's not a deadly threat - don't shoot. If you're faced with a deadly threat, apply your training. You have one chance to get this right. Fine motor functions and complex problem-solving are out the window. You'll be left with gross motor skills, because of the adrenaline dump your body is dealing with. Keep it simple, set the gun up simple, and train simple. Know your route through your hose. Address the threat, and clear your house, safely. BREATHE!!!... While your brain is going haywire...

No way, man... Welcome to the NutHouse. You've achieved proficiency, talking about the same thing more than once or 7 times. Welcome Aboard...

It sucks being deployed during holidays. Sucks ass. December 1989 I was in Panama. Jan through Aug 2002 I was in the PI doing the GWOT-Hunt-ASG game, so all those holidays in there. T-Day 2003 I was in Afghanistan, 12-hr notice deployment on Nov 9th. Yes, Vets Day weekend, long weekend off for .mil folks. Longer weekend for SF folks. Nope, move out. Grab a plane. Officially notified to grab gear/guns and go at 1400, wheels up 2300 that night. We had a week-long hint that it was coming, so we were on the range, re-zeroing optics when the real word came down. Shut it down, men - get to the team room and gather your shiit. Now. 88/89 was Korea, late 91/92 was Korea, 94 was Korea, early 97/early 99 was Korea. More than 6 years in that country, total, counting the 4 tours and 10 TDYs. TDYs all over the planet all the time, training deployments, ,most time I ever had at one unit was back at Group 99/04, five years without a PCS. But all over the planet during that timeframe, combat deployments, training deployments, exercises. Ain't a damn thing about .mil life that's easy. 21.5 years. Moved 22 times, total, overall, from place-to-place-to-place... Move from this station to a school, move to another school, move to next duty station... Worth it all, in the end. Never be able to replicate or replace any of those memories, places, or friends. I try, through you fuqrs...

Is your gun the American - Ruger American? I have the 300BLK 16" barrel, and love that gun - but want to change over that damn rotary mag to a box mag. Bad.

I'm loving the progression on this. It's rapid.

WTF...

My apologies, I didn't even see the diagnosis. I missed that post from you completely. If there's anything that any of us can do, just say it. Fight, man. Fight. If you want that upper fixed, I'll do it. I have spare Armalite gas tubes. Drilling the port is easy. All that would leave is swapping out the recoil system, and you have something you can enjoy. I'll take care of the upper and gas system. Wouldn't need a charging handle, wouldn't need a BCG, wouldn't even need the handguard on there. Stripped in a box, and it'll be on the way back to you right away. Think about it, and if you want, I'll get it done...

No worries, this is fixable so it will run everything. Still PSA. Might as well do the mods now, before you shoot it, so you're working on a clean gun. Let me know if that's a 16" or 18" barrel on that. Looks light 18" and it's mid-length gas. You'll need an Armalite AR-10 CARBINE gas tube for it. Trust my words on that. Get rid of the entire carbine recoil system that's in it now, and just buy the Armalite AR-10 Carbine Recoil System - they sell that as one part number. That will wolve your recoil system problems that you are going to encounter with what you have now. So, only thing left is gas port diameter. If that's an 18" barrel - I can see it's midlength, and I can see it's a 0.750" journal size - so if it's 18", they drilled the gas port 0.070". You'll need to open that up to 0.085". 1. Replace the gas tube, yours is probably too short - a pic will confirm this. Take a pic up in the upper receiver, BCG removed, and show how far the gas tube protrudes into the upper receiver. It should be halfway into the cam pin cutout in the upper receiver. Yours is probably barely touching the front of the cam pin cutout. 2. Bring the gas port diameter up to what it needs to be. 3. Replace the entire recoil system with the Armalite AR-10 parts kit. Done deal, functional rifle, not harsh recoiling, and eats just about anything you'll feed it.

@BeeKay, if you're looking for the proper spring that will work, tell me what the details are on your gun. I can give you the information that you need. I just need to know the setup on the gun. P.S. Don't worry about what other guys are doing when they're charging their gun. It's either setup right, or it's not. It'll last forever, not beat up parts, eat any ammo - or not. I can tell (obviously) it's a fixed stock, so the extension is a rifle extension. The rifle buffer needs to be 5.200" long and weigh 5.4oz. If the spring was PSA, throw it away, and buy the Armalite EA-1095 spring or the Sprinco Red spring. That will fix the recoil system, forever. The gas system is another story. That might need attention. That's where the details come in.

VERY Well Done!!!

It's a PSA PA-10 Gen 3. PSA bought DPMS during the Remington breakup. Expect all the PA-10 issues with this one. Here's the DPMS DP10 from the DPMS website: Here's the PA-10 from the PSA website: Here's the history of what/how things went with the Remington Fiasco: https://www.guns.com/news/2021/08/05/bushmaster-dpms-panther-arms-black-rifle-brands-revived
