Brownells Gen2 BRN-180 Uppers – First Look

Brownells announced the next generation of its BRN-180 uppers, including the much-anticipated version chambered in .300 AAC Blackout, perfect for use with a suppressor.

Brownells Gen2 BRN-180 Uppers – First Look

Launched at SHOT Show 2019 in Las Vegas, Nevada, the BRN-180 uppers combine features of the classic AR-180 with modern upgrades such as a full-length Picatinny rail and a free-float M-LOK handguard.

All BRN-180 Gen2 uppers are ideal for folding stocks or braces as the recoil mechanism is totally contained inside the upper.

The BRN-180 Gen2 updates include a new method of securing the handguard and adjustable gas blocks for all barrel lengths to optimize suppressor use.

The newest model has a 10” barrel chambered in .300 AAC Blackout, well-suited for a building a BRN-180S pistol or a registered short barreled rifle.


The other Gen2 BRN-180 uppers are still chambered in .223 Wylde to maximize accuracy potential with both 5.56 and .223 Remington ammunition.

Shooting 600 Yards with .300 Blackout

The .300 Blackout cartridge was developed to provide greater effectiveness than a 9mm at short and medium ranges when fired from a short-barreled suppressed firearm. Just because the cartridge wasn't designed to go long doesn't mean Rifles & Optics Editor Tom Beckstrand won't take it there, using a large-format pistol, no less. Armed with SIG Sauer's 9-inch-barreled MCX Virtus Pistol loaded with Black Hills' 125-grain TMK ammunition, Beckstrand attempts to ring steel at 600 yards with help from Hornady's 4DOF ballistic calculator in this segment of “Long Range Tech.”

Former U.S. Navy SEAL Jeff Gonzales, president of Trident Concepts, joins G&A contributor Kimberly Heath-Chudwin to discuss guns, training and gear, including Blackhawk's TecGrip holster that can make pocket carry more successful.
