Ok yeah that makes sense as there is a lot of variables at play. The jp setup is 5 ounces which seems heavy but from reading on it it could possibly work. But that is correct I believe the .308 is about an inch shorter maybe more due to the bcg being longer. Do you have a carbine length tube that you are gonna use for that buffer?

Yes, luckly I found a complete lower kit. Pre crazy prices. I've been toying with the pistol idea since last year.

I ended up buying complete buffer system kits, rifle and carbine. Both buffers are shorter than AR-15 parts. Not sure about the springs. I just used what came with the kits.

I just bought a matching set that was a blem set for 189.00, my son paid for everything else. Aero Precision BCG, kak shockwave tube/brace, CMMG LPK, Muzzle brake, and handguard rail. Still waiting in a barrel.i think we are at about 600 into it now.

What buffer system kits did you use for the carbine? Also do you happen to know the weight of the buffer in the carbine kit?

That blade brace might be a bit "pokey"

Yeah I have one on a 556 pistol. I know theres a lot more recoil with a 308 but its gonna be my son shooting it. If he doesn't like it, then he can replace it. He will be a man 25 MAY 21.

A couple years ago I did a 7.62x39 rifle bling build. Had this cool anodized, skeletonized stock with matching grip. They both were replaced after 1st range session. Too edgy. Would have been fine for 223...

My dust covers came in. And so did some Hexmags. Hopefully I'll get time to assemble this weekend. I ended up with an extra nitride bcg, if anyone is interested. Oh make that 2 bcgs. One standard dpms. The other has dual ejectors- enhanced? gen2?
