Bushmaster is now offering an upper for the .300 BLACKOUT (aka 300 BLK or 300 AAC BLACKOUT) cartridge. The uppers use a light contour barrel with a black Melonite coating. Barrel length is 16″.
The AAC Blackout 51T ratchet mount flash hider is used on these uppers. The upper receiver has a flat top with Picatinny rails for mounting a wide range of optics and iron sights. The gas block is low profile and does not have a built in front sight post.
The handguard is a quad-rail allowing for the addition of many different accessories such as a white light or laser. MSRP is $869. In current market conditions, prices could be higher than the MSRP, assuming Bushmaster ships these in any quantity.
