Brownells BRN-180™ Gen2 - An Introduction

What happens after you start the "ARevolution" with a new gas piston AR-15 upper receiver? You improve on it, of course! Brownells new products team leader Paul Levy introduces the new BRN-180™ Gen2 upper receiver. Everybody who has a "Gen1" can relax: the original BRN-180™ is an outstanding upper. It's just been made even better. The original BRN-180™ short-stroke gas piston system remains unchanged, except now ALL Gen2 uppers come with the BRN-180S™ adjustable gas block. The handguard attachment system has been greatly simplified. Now, you loosen ONE screw and slide the handguard off the rifle. When the screw is tightened, it actually presses the handguard against the receiver. No matter how many rounds you fire and how hot the upper becomes, this handguard will not move - good news if you have your laser or other sight mounted on the handguard. Almost from the moment the original BRN-180S™ was released, folks were clamoring for a .300 Blackout chambering.... And here it is! The BRN-180S™ in .300 Blackout comes with a 10" barrel and 5/8"-24 tpi muzzle threads. Begs for a suppressor, doesn't it?

WARNING: Never attempt to disassemble or reassemble a firearm unless you are absolutely certain that it is empty and unloaded. Visually inspect the chamber, the magazine and firing mechanism to be absolutely certain that no ammunition remains in the firearm. Disassembly and reassembly should follow the manufacturer’s instructions.
