SB Tactical SBA3 Brace

The SB Tactical SBA3 is an adjustable pistol stabilizing brace in FDE finish included with this kit. It is compatible with mil-spec diameter buffer tubes and offers an adjustable fit across multiple positions. The SBA3 pairs directly with the Davidson Defense mil-spec carbine buffer tube included in this bundle.

Davidson Defense Buffer Tube and Armaspec H3 Buffer System

The Davidson Defense carbine buffer tube is 7075-T6 aluminum with a Type III hardcoat anodized exterior and an internal dry film coating. The dry film coating reduces internal friction across the buffer tube channel. The tube uses standard AR-15 receiver extension threading and is compatible with mil-spec AR-15 lower receivers. The Armaspec H3 Sound Mitigation Buffer Gen 3 is a captured buffer and spring assembly with a polymer guide rod base and adjustable internal spring weight, weighing 5.6 oz as a single-stage drop-in replacement. The H3 weight configuration is compatible with forced reset trigger setups on the AR-15 platform. The US Tactical mil-spec steel receiver end plate and standard AR-15 carbine castle nut complete the rear hardware group for the lower receiver.
