Yep, that's it, brother! If some of the shiit you put into your rifle has it's OWN shiit going on?... Suspect Foul Play. Move to less complicated parts.

Help me understand this. You're taking 300BLK cases (shortened 5.56 case, from start, technically a 7.62x35 case), and then necking those 300BLK cases down to .224? Basically a barrel chambered for 300BLK, but bored for .224?

^^^ What he said. Here's what's on Sprinco's website: Extra Extra Power Buffer Spring. The Orange spring is much stouter than the Red spring. The Orange buffer spring was originally engineered for the demands presented by.308 / 6.5 CM / .260 Rem, etc., heavy BCG carbine DPMS Pattern applications using standard 7" Depth M4 extension tubes and short 2.5" buffers (Including aftermarket "heavy buffers") in robustly gassed 16” - 18” ML gas carbine platforms, but has been proven to be a requirement for tuning over gassed carbines of any equivalent heavy calibers in AR-10 pattern tubes with 3.25" buffers or lesser calibers (5.56, etc.). Color Coded ORANGE. Nobody else on the market makes a spring specifically for the 7" receiver extensions and short 2.500" buffers for the large frames. EA-1095 and the Sprinco Red are direct equivalents, and function great in large frame rifle recoil systems, and carbine systems with the 7 5/8" internal depth carbine extensions running 3.250" buffers, as well as running in the rifle recoil extensions (9 11/16" internal) running 5.200" long large-frame rifle buffers. Sprinco Red works great in my 9mm PCC, too. 7.000" internal carbine extension, Sprike's 8oz longass pistol buffer. I haven't tried the EA-1095 in it yet, but I will. Just to confirm it. Right now, it eats anything you throw in it, suppressed or unsuppressed.

The .300BLK case, with a .224 projectile... That's called .223 Rem or 5.56 NATO. That's exactly what it is. WTF are you doing here?

It's MPI and HP. Not MP. Magnetic Particle Inspected, AFTER firing a High Pressure round - HP - a "proof load". That does not indicate a manufacturer, it's just proof that it's tested for MPI after HP - if it's even done. Lots of manufacturers pay for that process, and mark their bolts as such. It's also not done on every bolt in the batch, for alot of manufacturers - that's what "batch testing" is about in this industry. They might test 2 out of 100, 47 out of 50 - you don't know unless you contact them directly and ask. Closest I can find, and they cut off the MPI to MP...

My sentiments, exactly. That good-not good-good again - now it's illegal... That already kicked them straight in the dick. Then, West Virginia Vs. EPA happened... And that changed everything for these .gov agencies. If WVa vs EPA is never overturned - then that's forever...

I'm telling you, in Afghaniland November 2003, 2/75 deployment - we were on a refit back at a mountain base, and it was him and another dude with guitars in a mud hut, singing about alien ass-ravage... I seriously need to meet him, and ask him about that...

I wanna buy that book... I can only imagine...

Man, I'm just glad the gun is running. Seriously. This is a science now, on how to fix these things, and apply the proper parts to do so. I wish more people knew this, and more people applied it. I thank YOU for applying it, and making your gun run. I sincerely mean that.

Toolcraft is is biggest supplier to OEMs. Back in the day CMT was the biggest supplier to OEMs on 5.56 stuff. Continental Machine Tool. One of the companies under CMT was Stag Arms. Dad owned CMT, son owned Stag. That's different now. White Wolf Capital. Here's a rundown on that stuff: This all went down around the timeframe that Aero "started using their own BCGS" in their guns, rather than using ToolCraft BCGs. Makes sense, connecting the dots.

Just reading through this a little. DPMS. There is no such thing as "Gen 1" - ever. There's the DPMS LR-308. It's not "Gen 1" or "Gen anything" It's the DPMS LR-308 model. Comes in many configurations and flavors. DPMS decided to "shrink the receivers" and devised a way to make a .308 Win (large frame) platform with smaller receivers, smaller in many areas, and touted that it would work with any AR15 handguard. That was the DPMS G II platform. It's not a "Gen 2", it's the DPMS G II platform. Not enough information out there about this, and I wish it was prolific and rampant, across the message-board planet - but not enough people understand it, and put out a metric shiit-ton of misinformation on it. There's my $0.02 so far...

You have valid points, brother. You also have a Mile Gun, very easily. You know that. Fuk, we can Mile it with the Win Mag parts. We'll Mile it with the .338 stuff first, though...

DAMN! I didn't know the thing cost that much!

Yeah, I care. You're not about listening, just talking. haha Fix the project you're working on now, show me you're serious. Otherwise, don't contact me about your mile gun dream. Shoot this one first, make hits at 1100, beyond transonic, make it win. Come back, show results. haha

You can piece it together yourself, if you know what specific individual parts you're looking for, and want to spend more money. Or, you can shortcut that process, get one part number for one price, from one company that doesn't fuk it up, ever. That includes the recoil system that you really need to make the gun run right. Your call.

There's only ONE PLACE to start testing an adjustable gas block. Wide Open. Nothing less. You have alot to learn, so Brace Yourself.

The best recoil system was the very first reply that you received, in this thread. You need to go back and read the first reply you got in this one. There's really not 2 or 3 good options - there's one option, to do it right for this platform. Especially for a .308 WIn gun. It's already figured out and proven, over decades.

Well, there's very few things that are gonna give you hits at 2500 yards, but I'm glad you have that kind of distance - it's a gift to use, I know well. You need to start with 375 Chey Tac to make that a reality, if 2500 might really be the goal sometime. I don't even think .338 Lapua will do it, with regularity, at 2500. That's some serious distance. I shoot .300 Win Mag at a mile. 1760 yards. Custom handloaded ammo, Do it routinely, and several people here have both seen it being done, and done it themselves. That ain't easy, at an IPSC plate target that's 18" wide and 32" tall. That's not even 1 MOA wide at a mile, when you run the math on what 1 MOA really is. 1.047" at 100. .308 Win is never gonna get half way to 2500 yards, accurately, no matter how you load it yourself. My very best .308 Win handload is a really kickass load, Hornady 178 ELD-X - the very best .308 Win projectile they make - and that thing dips into the transonic barrier after 1050 yards. By 1100 yards, it's already subsonic. And tumbling. Let's get a real estimate on what you think this gun will do for you, and what you expect of it, and then we can get serious about giving you recommendations. Or not. Up to you. We really do shoot Long Range here, and it's no bullshiit. Long Range isn't 600 yards, or 800 yards, or 1k yards - that's a warm up, here, for about 26 people that are on this board as members. Next up, this March - we're setting up 2,000 yards, and testing our Mile Guns that are known to hit the Mile, on the 2k target. Shouldn't be that hard to coax another 240 yards out of them, right?...

Don't Complicate Shiit with Complicated Shiit. I live by that. It works.

Definitely. You never solve simple problems with complex solutions. Simple problems are solved with simple solutions. Here's my deal on recoil systems. it's fairly blunt. You have a receiver extension DEPTH that's either right or wrong. Say it's right. You have a buffer WEIGHT AND LENGTH that's either right... and you have a recoil spring that either WORKS... or it doesn't. You get into all these Race Gun parts, like the SCS you have in your hand - that's Race Gun shiit. You building a Race Gun? How much you planning on making this year, both from paid winnings, plus sponsorship money? Yeah, that's where all the Race Gun parts belong. They all sound badass, and cure any problem - but they're so fucking TAILORED to a specific ROUND LOAD issue - Race Gun parts make your specific handload WORK, to reach whatever Power Factor that the competition you're shooting needs to see... So you win money, or get your bragging rights. Race Gun parts are not plinking parts, they're not hunting parts, and they're not "I want my gun to shoot anything I put in it" parts... My $0.02, off my soapbox now...

Let's see how it runs. There's a bunch of number that are off, but risk it - you paid for it. Buffer weight should be 5.4oz, the list 5.0oz. Least I've ever made run right was 5.15oz, for a buffer. So, the expensive buffer is light. Let's risk it and see what happens. JP is Complicating Shiit With Complicated Shiit, and this says it all right here: The JPSCS2-10 is designed to work in standard 7-inch M16/M4-length buffer extension tubes on .308 AR-type rifles like the DPMS LR-308. Armalite .308 rifles, likewise, use these standard M16 extension tubes with rifle-length stocks, so this unit will function normally when installed with the supplied spacer. However, Armalite's .308 carbines use a slightly longer, non-standard carbine extension tube. The JPSCS2-10 can still be used with these extension tubes by installing the spacer, which must be modified to fit. Alternately, the system will function readily if the longer Armalite carbine tube is replaced with a standard 7-inch .223 carbine extension tube. That's their own description of this part that you have. It's ironic that they state the Armalite .308 carbine uses a slightly longer, NON-STANDARD extension tube... I LMAO over that... The Armalite AR-10 Carbine Receiver Extension IS the standard, for .308ARs... You're dabbling in Gamer-Gun shiit, with that recoil system -tailored for a certain load, certain gun, certain projectile speed - for matches, games, and playing around. That's cool. If you're a Gamer, and you use your gun for making money in competitions, against others, for determining hits on steel with major power factor, and less felt recoil. You're using Race Gun parts to build your gun, that work for Race Guns. What are you looking at from this gun? what is your intent for this gun? What are you gonna use it for, and what do you want it to do for you?

This one is pretty badass, because this covers the same timeframe that I was in 1st SFG(A). It's pretty cool, hearing this. What this guy is describing and talking about - some of the people - I worked with them. I know some of the dudes he's talking about. Pretty much mind-blown listening to this. For the record, the 1st SFG(A) CIF Team is (was) C/1/1, stationed in Oki. He talks about one of the guys that got his eye shot out during a training rotation - that was one of the guys that I worked with for a long time, talked him into really doing the real job, and getting Ranger qualified, as a support guy - like we're supposed to - and he did. He took that eye loss pretty hard. I get it - I know, and I talked to him for many days and hours about it, on the phone, after it happened. Potentially, you're out of the Army, without one of your eyeballs. I gave him possible options, all things considered. He stayed in, and went on to do greater things, with one eye. He turned into a Terminator Badass, with one eyeball, and went on to do great things for this country. I think I talked about it before, but he had a fake eyeball, battery-powered, that he could pop in, and it really was a Terminator eyeball, glowing red when it was turned on... Scared motherfuckers in a bar, when they saw that shiiit... His first name was Melborne, his name in Group was Meb. It was just easier that way. I won't give his last name, because I have no idea if he's even working in this field anymore, or with any agency these days. He was crippled, potentially getting kicked out for disability, but went on to achieve more than any of us did, with the direction he went. Badass. Listen to this one, it's pretty cool. It's REALLY cool for me, because I'm recognizing names, dates, deployments... What a ride...

For the record, I own 5 Wilson Combat barrels, and not one of them have a tight chamber. That's 5 barrels over 4 different calibers. Wilson Combat makes their barrels with their own Match Chamber, and it's where it needs to be. Match Chambers are definitely not loose chambers - they're tighter than a mass produced chamber, for a reason. I've never had an issue with headspace from one of their barrels, and a Toolcraft bolt. Not once. They don't have gas ports figured out, but that's easily solved. That's my $0.02 on WC barrels - they're accurate as hell, true match barrels.

Nope - that's the beauty of the tank trap - depending on what type of rifle you're using determines where you have to shoot from. You as the shooter need to figure out how to solve that problem. Here's an example of what I'm talking about - Open and Restricted Class shooters have to shoot from ABOVE the intersection of the sections of the tank trap. Tactical and Limited Class shooters can shoot from anywhere touching the tank trap - those guys can actually prone out on the ground, and touch the bottom of the leg of the trap with their elbow... Different classes, different rules - gotta figure out what you're gonna do to solve this shooting problem. SO, you think you have a good plan, and the timer goes off... BEEP!!! Click until this is big enough to read - it's about 3 clicks I think... Scuba Steve is a badass - he can fabricate ANYTHING. He's a great dude, great friend, massive skills.

Wilson Combat Tactical Hunter barrel in 7mm-08 caliber. 18" Rifle Gas, 0.750" gas block journal diameter. Ships with a gas port that 0.076". I'll check some math and see if this is gonna work.
