Look here, and focus on all the "DPMS High" stuff. https://www.primaryarms.com/1+Rails--AND--Handguards/MCategories+AR-308-Rails--AND--Handguards

Gonna be tough, finding an upper that matches that profile, just in the DPMS Low height. There are alot of DPMS High rails out there - that's what to look for.

I'd leave the primers in there, and take apart the resizing/deprining die - just take out the depriming pin - just unscrew it from the rod, if it's an RCBS, and take the removeable pin out. Run the cases through the sizing die to reform the neck, and you're ready to load them back up, brother. I'm using CCI 41 primers in all my Grendel loads now - they're slightly larger in diameter, and seat tighter. I noticed my primer pockets were a little loose, too - those CCI 41s solved that for me.

You'll have to break that castle nut staking free - looks like that one spot was staked pretty good. That buffer has an aluminum body and two tungsten weights in it. No more than 2 weights will fit. Only way to make it heavier is to get a DSG buffer with the stainless steel body. It comes with steel weights in it. Cross your two tungsten weights over into that SS body, and it'll give you a 5.15oz buffer. Or, buy a KAC Shorty heavy buffer that weighs in at 5.3oz. That's about as close as you'll be able to get. Put a Sprinco Orange spring in there for an operating spring. Try that first and see how the gun does.

That's a 2.5" buffer right there (when it's assembled). So this is what PSA is shipping now? That receiver extension does need to go in one more turn, and you will have to notch the bottom to clear the buffer retaining pin. That receiver extension must be 7.000" internal depth in order to run a 2.500" buffer on a .308AR.

That's one hell of a load!!! Awesome!

That is pretty damn cool!!!

I did. Entirely. Good Luck. If you feel stupid or inadequate, that's on you - you put yourself in that position, based on what you posted. Nothing to do with me, in the least. That's you, man. Deal with it, on your own terms. Also, I'm never on a "high horse" here. My only goal is to get information out. You've obviously failed to understand that. Again, on that note - good luck.

Infinitely delayed, right now - too much personal shiit. We're looking at 3 weeks out now - and it'll be HOT here by then. Whatever. We'll deal with it. In the meantime, THIS guy was ready to whip my ass at an intersection. I kid you not. He was small, but I was not about to fuk with a baby owl, full of attitude. He had the look - and I know that look well - this guy was just LOOKING for someone to fuk with him - and it was on... He was just chillin', at the stop sign - waiting for that fight... I love him, for that... I wasn't gonna challenge him... Bad MotherFucker!...

AR15 references, AR15, AR15, AR15... again and again, in both the links you posted. This isn't an AR15. This is what was developed BEFORE the AR15 was even a vision on someone's horizon...

Hey, Creed Love, go make an intro post in the Intro Section, and tell us a little bit about yourself, instead of piggying on a thread that's 4 years old. Explain it all, about you - then get into some technical threads about your problems, in the specific sections about that. That will help.

These are definitely not AR15s. Nowhere close. You can't apply any AR15 information to these things, besides triggers... Furthermore, recoil systems for AR15s are VASTLY different than .308AR recoil systems. Not by inches, or fractions.By miles. You need to understand the recoil systems between the two platforms - AR15 and .308 AR - before you make that comparison. That you just made.

The people that spend all the money on all the fancy race-gun parts - that don't work on "working guns," but work on Race Guns that are specifically built - are the most pissed off about it, and question us the most - they fight the most, over their expensive purchase of those parts. They try to justify them, and say those parts are the greatest - because that website TOLD them that they are the greatest... Most .308AR builds are NOT Race Guns. Competition Guns. Speed Guns. Call it what you will. Race Gun parts have NO REASON to be in a basic, functional .308AR rifle build - unless you're building that thing from the ground-up TO COMPETE and win money. If you want to build a functional .308AR rifle - build a basic rifle with basic parts, and skip that fancy shiit. The "fancier" you try to make it, with all the "complicated parts," the more you fucked up the true functionality of the rifle. Make a functional rifle first. Then fuk with it...

Crushed it, brother. Just crushed it.

I would keep it, if I was in your shoes - no way would I get rid of that rifle. And no way would I chop that barrel - that thing in damn near perfection, just as it is, man. That is one hell of a great rifle, just like that.

I'd just love to know what sites you're looking at that tell you that the rifle buffer "totals around 5.0oz..." That's BS, from the sites that you're gleaning that info from. Just so you know. Please list them, so we know what "informational sites" we know here, to mark as bad info...

Stock rifle-length buffer weight is 5.4oz. Not 5oz. That makes an operational difference, when all other things are "stock." How you make that expensive JP Silent Captured Spring system work on your gun, when the other one worked - that's JP's problem. Increase that buffer weight to 5.4 oz on the JP system, and make sure their spring matches the same spring dimensions/actions of your previous spring - that worked - and you're golden. At this point, you need to ask JP what the answer is, and why their own system doesn't work - when your previous system did work. JP needs to tell you, not us. They made it. Not us. JP race gun parts falls into that "complicated shiit" category that I was talking about. They make GREAT Race Guns. But, you "complicated shiit with complicated shiit," and added Race Gun Parts to a normal rifle that's not a Race Gun. I"m not insulting you in any way, but that's something like adding 110-octane race gas to your commuter car, and expecting it to perform differently. It's actually detrimental to it's performance, when it's designed to run on 87...

It's not at all "complicated" to me, in the least. I understand all of it, completely. I just build these things based on what I know, and have learned, then run the gun. I don't have functional issues with my builds. I use my own combination of recoil system parts, I check the gas tube length, and I measure the gas port diameter. If anything is off with the gas tube length, I fix that. If anything is off with the gas port diameter in the barrel - I drill it. My recoil system never fails me (now), not once, ever (after I learned why the first one was completely FUBAR'd and jacked-the-fuk-up - FROM a reputable manufacturer). I build functional guns, and they run, right out of the gate, everytime. That's only based on learning that there are manufacturers out there that don't know what it takes to make a "functional gun." My first rodeo with a carbine recoil system was my last - I dove head-deep into learning WHY it fucked up, and got hip-deep into recoil systems. At that point, I had my own answers, and never looked back. You stated yourself that it ran before. You need to look at what you changed, to make it into a non-functional rifle...

How is she assembling guns, like this?... 😁

You never, ever need "a bigger safe." You just need "another safe." It's as simple as that.

Your gun ran fine with a rifle-length buffer and spring, before, and the issues have cropped up now? Start with a buffer weight of 5.4oz, and see where you go from there. H2 weight is 4.6oz. JP Rifles are awesome at race-gun shiit. Are you trying to build a competitive race-gun - or an operational gun?... Start with an operational gun, then do what you want, piece by piece. I'm here to help you, not battle you. Your gun doesn't work right now. I'm trying to get your gun to work, then you can experiment. Comprende?...

Faxon has a limited edition run of Titanium Nitride PVD coated barrels out now. They're GOLD. Check it: https://faxonfirearms.com/rifle-barrels/limited-edition/?_ke=eyJrbF9lbWFpbCI6ICJyZ3JoYXJ0bGV5QGhvdG1haWwuY29tIiwgImtsX2NvbXBhbnlfaWQiOiAiS2pSUWl1In0%3D @MikedaddyH needs one of these, for a very specific gun!...

Start this in it's own thread, instead of tagging a reply to a thread that last saw life on 4 May 2013. Kudos for the reasearch, big time, but your question stands alone. Start a new thread, guy. Brand new. Only your question.

In a very, very minimal way... by the way...
