Description

The Dirty Bird Industries SBA3 Lower Build Kit includes everything needed to finish your AR Pistol Lower Receiver using the ever popular SB Tactical SBA3 Stabilizing Brace. This kit includes the Dirty Bird enhanced Lower Parts Kit which features our 5-star rated Nickel Teflon Single Stage Trigger Group. This trigger features honed and polished engagement surfaces, a slick and durable Nickel Teflon finish and finely tuned trigger / hammer spring rates.
