Glock 17 slide and internals. Lower parts kit for 80% lower. Still waiting for the spring that holds the takedown lever in on my g23 build. Damn thing is here somewhere but I can't find it. Those little springs are out of stock almost everywhere.
More Grendel mags and Glock mags for the 2new pistols.
Was going to buy some more Grendel ammo on Gunbroker. The American Gunner Grendel ammo I paid $139.00 for 200 rnds last spring got to over $3.00 a round on an auction. NO THANKS. Don't need it that bad.
The PSA bcg,'s are dpms pattern. Ballistic Advantage barrel fit in my PSA upper just fine. Rail was dpms high from local gun store. Yes Aero is easier to find stuff that works. The PSA upper will probably only fit a PSA lower.
Glad you got it running right. I think the only thing on my PSA that is still original is the upper and lower receiver and take down pins. And the bolt carrier group but it has a different ejector now.
Also check the ejector face. Is it square or rounded ? My creedmoor had to have a rounded ejector before it would run right.

Just use whatever recoil system and stock you prefer. The uppers barrel length has nothing to do with the stock configuration as long as the gas port and tube are set up properly.
Unless you are going to suppress it you don't need an adjustable gas block. Just get the rifle running right and tighten everything down good and tight and be done with it.
I dimpled the barrel for the gas block then just snugged up the set screws. If you want a thread locker on the gas block use Rock Set. Locktite will loosen with heat and the gas block gets hot.I have reused gas tube pins getting them out just requires the proper roll pin punch.
At my buddy Dutches house. He is a class 3 dealer and manufacturer. We were talking about the 40mm pump grenade launcher a while back. Here are pics of the 1 he has.
