I'm waiting for my Form 1 to clear, and I'm curently weighing my options for an SBR upper for my Bushmaster.
The Form 1 lists 10.5" barrel length and 5.56 as caliber, so I need to conform to this for the initial upper. Since I'm planning to use it subsonic/suppressed, I have to have 1/7 twist. Also since 5.56 subsonic doesn't typically cycle the action, I'm thinking about an LAR left-side charging receiver (OPS-4). Also going to have to have a YHM QD flash suppressor (for my YHM 7.62 Phantom).
Now I'm also thinking about a .300 BLK upper (after L1A1Rocker's liver of sulfur GD post). Probably going with a Delta Company Arms Delta-43 upper (9" barrel, LAR OPS-4 right-side charging upper, Samson rail). Also going to need a YHM QD flash suppressor (also for the YHM 7.62 Phantom).
These will be going on my Bushmaster lower (which is going to be getting a Timney trigger). I'm leaving the full-stock on it (don't really like AR telescoping stocks).
Probably going with EoTech for the sight.
