WTS a few complete uppers. If interested send me a PM as email from this forum will not reach me. Shipping is $15.
BCA 10.5 inch 6.5 Grendel upper, BCA nitrided 1:8 twist barrel with pistol length gas system, low profile adjustable gas block, 9 inch Diamondback free float MLOK handguard, A2 flash hider. Complete with bolt carrier group and charging handle. $300
This upper can be considered new with no blems but it does have 14 rounds through it to tune the gas system to lock the bolt back on steel cased Wolf using a standard weight 3 oz carbine buffer.
For $275 I can substitute the Diamondback free float rail for a plastic hand guard with a set screw gas block to retain the handguard.
A “dissipator” style system like this makes it much easier to get access to adjust the gas block without carrying around an additional Allen wrench to remove the rail. I personally like the comfort and additional insulation the M4 hand guards provide more than the rail after the barrel heats up, and with the HBAR barrel profile and short length, the accuracy difference is unnoticeable. I have a set of green handguards shown in the pic but also have some black hand guards that were cut for an AA piston setup as well if you prefer. If you have your own handguards you want to use subtract $10, or if you have another setup in mind I can also remove the forward gas block and handguard retainer to subtract another $20.

Next I have a YHM 11.5” 7.62x39mm upper with a YHM 7.62 marked receiver, YHM 11.5” 1:10 light profile chrome lined carbine gas barrel, YHM 9” lightweight free float hand guard, AIM surplus 7.62x39 NiB BCG and CH. Test fired to confirm bolt locks back on empty mag. 1/2x36 TPI muzzle. No muzzle device installed but I have a Smith Vortex that will fit for $75 and a 5.5” extended FH for $25.

Finally I have a YHM 7.62x39mm marked upper with a 18” 1:9.5 nitrided light profile midlength gas barrel threaded 5/8x24 with an A2 flash hider, 15” MLOK lightweight free float hand guard, AIM surplus 7.62x39 NiB BCG and CH. Test fired to confirm bolt locks back on empty mag. It locked back on standard 125 gr supersonic as well as 220 gr subsonic brown bear. Smooth shooting with the midlength gas and the long 18” barrel gets a few extra FPS and reduces noise just a bit while still remaining light and handy. If you prefer a shorter length handguard I also have a 12 MI MLOK handguard and can also replace it with standard plastic or MOE handguards and a pic rail gas block
