The BB9 is the optimal “truck gun”, predator/varmint hunting, and target shooting pistol. The small size, ease of use, and 9mm caliber allow you to maneuvre your weapon easily and quickly. When designing the BB9, our team saw there was a product missing in our line up. We wanted to recreate the image of an AR9 pistol, and our BB9 is the perfect option. Our team has used it for Texas predator hunting to take down pigs, coyotes, and bobcats.

Our 9 MM

The SBA3 is a five-position adjustable, versatile brace with an ambidextrous QD sling socket. Made in the USA.
The Brace Built Drogheda grip was crafted for the BB9, machined from 60 series billet aluminium in Garland, TX. Textured with vertical lines on the edges, with 7 cut out notches on the back and five on the front for optimal grip.
Oversized ambidextrous charging handle featuring a laser engraved Brace Built logo.
Upper is skeletonized to take off weight and relieve gas and feature eight slots on the right side.
Oversized mag release, machined in house from 6061 aluminium billet.
Our BB9 is compatible with any Glock 17 & 19, 9mm magazines. We have used Glock, PMAG, and ETS. Orders come with one translucent, orange 31 round ETS mag. It holds up exceptionally to outdoor elements and easy to see ammo left in the magazine.
The A2 birdcage decreases muzzle flash and compatible with a 1/2″ x 28″ threaded barrel. Giving a clean finish to the BB9.

For those who would like to replaces the A2 birdcage with a suppressor or other muzzle device, the birdcage is Loctite! In order to remove the A2, you must use a source of heat, like a heat gun to loosen the seal.
