So now the LR .308

OK, without the rear takedown pin installed, does everything look correct? Gaps all line up? close up all the way? If no, maybe takedown pocket not deep enough. If yes, I've seen slotted rear takedown holes, no big deal. Takedown is the "Give" when aligning the 3 points of 80% frames, front pivot and extension tube the other two.

I'm thinking Toolcraft. I'm gonna call Heavy Buffers for the tube, spring, and buffer. I

Toolcraft Yes.

I like the Armalite recoil kit.

Progress - A little oil, a delrin drift, and a plastic coated hammer were all it took to mate things up! 😬 Are the pins tight? YES, especially the rear. But with a couple of in and out moves its loosening up. I'll work it some more tonight. The fit is excellent IMO. No movement anywhere whatsoever. It locks up like a champ. Here are some pics.

 

Mated

Aero fit to the lower

Tang - the fit is much better than it looks. No light passes through anywhere

Gas tube - nice machining on the upper

My only question here is it the correct spring and buffer for a DPMS build? Other threads have said that Armalite and DPMS approached things differently. DPMS using a stiffer spring and a lighter and smaller sized buffer to work with AR15 parts.

If you use the armalite recoil system the gun will run providing the gas port is the right size. I have built 2 308 pistols using the armalite parts and all I had to do was get the proper amount of gas to the recoil system for them to run well. Takes the guess work out of the equation.

The ArmaLite recoil system works very well with DPMS. The distinction is that ArmaLite did it first, and very well, which is well demonstrated by the fact that their recoil system will work well in a DPMS.

Thanks guys. I was stumped on this reading posts, vendors listings, etc. That said, I'm  sucker for the A2 that Albroswift mentioned.

Shows out of stock but call them. Usually if you call they will hook you up.

Looking good! Almost smell the burnt powder.
