Picked up an upper and decided I wanted to do a 300 Blackout instead.
Unfired PSA upper. 1:7 twist, 18" barrel. 15" Midwest Industries MLok handguard.
Looking for a pistol upper first. If not a rifle upper will work. I have a BCG and charging handle if your upper has one.
Value is $270...
Parts needed for pistol build. I have a AR 9mm block type lower and a side charging upper. Just need part to complete the build.
AR-15 9MM barrel, 7 to 9"
Hand-guard/rail prefer M-Lok. No quad rails. 7"
BCG for 9mm AR, needs to work with glock mags
Lower parts, want something like Strike...
