Brownells BRN-180 SCNR 300 BLK 9" Upper Receiver Assembly

Brownells sells this BRN-180 SCNR as a complete upper receiver assembly chambered in 300 Blackout, with a 9 inch barrel and a black finish. It is the whole top half of the gun with the barrel in place, not a stripped receiver that still needs parts.

A 9 inch barrel keeps the build very short. Barrel length on a rifle is regulated, so make sure your finished configuration is legal where you live before you assemble it, and confirm the lower receiver you plan to use is made to accept a BRN-180 upper.
