    Why an AR pistol? Why not just run a 300BLK rifle, like I did? 2350-2400fps with Hornady Custom 110gr VMax ammo and 3/4 MOA. No need to deal with the accuracy issues that come from not shouldering a pistol.

    If you really want a shorter barrel, go SBR with it. A 10.5" or longer barrel will qualify for the 29"> requirement as part of FSA2013.

    Ok, ok 6x45 not for you . Enough for deer, but not maximized for .223 casehead.

    .277 Wolverine and .300 B'O will give essentially same ftlb, comes down to SD vs Diameter, aka tastes great vs less filling.

    The 7.62x40 will add another 100fps or a bit more over the Black Whisper , but gives up possibility of effective subsonic. Aka apples vs peaches.

    OR , disregard your pile of .223 brass, 7.62x39 ammo is cheap.
