Seller's Comments and Description:
For sale is a BRN-180 upper receiver for an AR-15, along with a picatinny stock/brace adapter. The upper receiver will fit on any standard AR-15 lower receiver and can be fired with the stock/brace folded or detached depending on preference. Comes with a 2-position adjustable gas system for use with a suppressor, which in my experience works fantastic. Specs: Caliber: .300 Blackout Barrel Length: 10 inches Muzzle Threads: 5/8x24 Color: Black I've only shot roughly 300 rounds through this upper, and it is in great shape. DUE TO A LARGE NUMBER OF UNRELATED SPAM CALLS, I WILL ONLY CONTACT INTERESTED FOLKS THROUGH TEXT. THANK YOU.
