New for 2019: Brownells BRN-180S Upper Receiver

posted on April 17, 2019
Fans of the AR-18 and AR-180 enjoyed the SHOT Show 2019 release of the Brownells BRN-180, an AR-18-inspired upper receiver that uses the same self-contained operating system as Eugene Stoner's original design. This rids the upper receiver of the need for a buffer-tube extension, and the Brownells BRN-180 also features modernized components, like the M-Lok-compatible handguard and the flattop upper receiver equipped with a Picatinny optics rail. In mid-2019, Brownells built on this new offering with the launch of the company's short-barreled BRN-180S.

"The reaction to our 2019 SHOT Show announcement of the original BRN-180 was one of the largest, most-positive we've seen," said Brownells Director of Product Management Paul Levy. "The most-common request from customers was for us to come out with a short-barreled version of the BRN-180. Thanks to PWS and FM Products, we were able to do that."

Like its big brother, the Brownells BRN-180S is equipped with an M-Lok handguard and a flattop Picatinny rail. However, instead of a 16-inch barrel, the BRN-180S is equipped with a 10.5-inch barrel that's compatible with all standard AR-15 lower receivers. This allows consumers to construct AR-pistols with a folding pistol-stabilizing brace or, with NFA approval and a tax stamp, a short-barreled rifle.

Unlike the original BRN-180 upper receiver, the short-barreled model is outfitted with an adjustable gas system with clear markings for suppressed and unsuppressed use. The barrel is chambered for .223 Wylde and features a 1:8-inch twist rate. Other features on the upper receiver include twin internal guide rods, a polymer ejection-port cover, three-prong flash hider and reciprocating charging handle. The suggested retail price on the BRN-180S is $799.

High-Tech Handloading

I now keep all my ammunition-creation data on a computer. Sure, I’ll make notes when working up a new load or tweaking an existing one, but ultimately my data is stored digitally. Since my loading room is only steps from my computer, the transition from written to digital data has been easy for me. Now that I’m using the handloading app from RCBS, it’s even easier, and it also makes recreating my favorite loads when I’m at the loading bench more convenient.
