Purchase the Dirty Bird SBPDW AR-15 Lower Build Kit here!

The Dirty Bird Industries SBPDW Lower Build Kit includes everything needed to finish your AR Pistol Lower Receiver using the ever popular SB Tactical SBPDW 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. This means you get a smooth trigger pull with very little take-up and a crisp clean break at 5 – 5.5 pounds. Additionally you’ll get an enhanced polymer trigger guard and an extra takedown / pivot pin detent and spring in case one gets lost during installation. The kit also includes the Dirty Bird AR-15 True Mil-Spec Carbine Receiver Extension / Buffer Kit. This popular buffer kit features a true Mil-Spec 6-Position Receiver Extension (buffer tube) machined from American Made 7075-T6 Aluminum, 3oz Carbine Recoil Buffer w/ steel counter weights, a chrome silicon buffer spring, hardened castle nut with staking cuts and mil-spec end plate.

Because there are so many grip options on the market and shooters are so different in their preferences, we’ve opted to simply include an A2 pistol grip as a part of the kit. This gives you something that is perfectly functional but doesn’t really add to the cost of the kit and enables you to choose whatever grip you’d like for your build.

Each component in this kit, down to the springs and detents are sourced from the best of the best and they’re all 100% American Made.
