Brownells Launches BRN-9 Complete Upper Receiver

Brownells customers can quickly assemble a 9mm AR-15-style firearm with the BRN-9, Brownells’ newest BRN Series Complete Upper Receiver, in stock and shipping now.

A self-contained upper receiver chambered for 9mm, the BRN-9 is blowback-operated, works blanked or blanked without adjustment, and fits any standard AR-15 or BRN-180 lower receiver.

Because the top does not require a set of shocks, it works easily with a folding stock like SBR or without a stock like a pistol. For the 9mm SBR configuration, all NFA standards apply.

The BRN-9 is compatible with both 9mm bottom loaders and common 9mm magazine well adapters, including those from Glock, Sig, Colt, CZ Scorpion, and MP5.

The top retains the deadbolt closing feature and is powered by the latest round deadbolt that holds the bottoms open. The non-reciprocating charging handle can be switched to either side.

The barrel is 5.5″ long and has 1/2″x28 muzzle threads. The integral Picatinny rail makes mounting optics or scopes easy and simple.

The BRN-9 top is listed on as SKU 430103679 and retails for $550.
