    Hi guys been looking for a 300 upper and looking for suggestions. I want to run suppressed mostly. Been looking around and can't seem to find "the one". Thanks in advance.

    I have three core15 uppers in .300 blackout. I'm keeping one. They are **** hot, accurate, solid and I love the stopping power of the .300 bolted up to a .223/5.56 lower. Oh, and my 10 year old is absolutely confident with it.

    Thanks for the reply. Core is one brand I was looking at.
    CMMG was the other. Still undecided.

    I just saw PSA is now selling 300 uppers, they were in stock yesterday and now they're gone. Does anyone have one?

    As mentioned, I have two I'd consider selling. Both are Core15 chambered in .300 BLK. Forged 7075-T6 M4 Flattop Uppers, 16" 416R Stainless barrels, bead-blasted, 1:8 twisties, 5/8"x24 tpi, Surefire flash hider, low-profile gas blocks, CORE15 V.2 Hardcore Billet Charging Handles, Chrome lined 8620 Steel MPI BCG's. Neither have been fired.

    One has a Midwest Industries floating battle rail, the other has MOE furnitue (black).

    Email me @ jeffrey.cooper@hp.com if you're interested.

    Mine is PSA. Shoots subs/supers un suppressed. My can is pending for another 6-8 months.
    I have a PSA lower to mate with it.

    Some people have issues with CMMG and cans. Others swear by them.
