This complete AR-15 lower build kit delivers ambidextrous functionality through a milled ambi bolt catch slot with included ambidextrous bolt catch kit and ambidextrous safety selector, paired with a forged 7075-T6 aluminum serialized lower receiver. The Gauntlet Arms polymer stabilizing brace provides high strength construction with integrated sling loop in black finish. Built around black hardcoat anodized finish and complete pistol buffer components, this kit supports left and right handed operation for AR-15 pistol platform builds requiring enhanced ambidextrous controls with durable polymer brace design.
The lower receiver features a milled ambidextrous bolt catch slot that accepts the included ambidextrous bolt catch kit, allowing both left and right handed shooters to manipulate the bolt catch and release without shifting grip or reaching across the firearm. The ambidextrous safety selector extends this left and right handed functionality to fire control, enabling shooters to engage or disengage the safety from either side of the receiver. This dual ambidextrous configuration supports complete weapon manipulation regardless of shooter handedness or shooting position. The factory milled bolt catch slot eliminates the need for aftermarket machining or adapter components.
The Gauntlet Arms polymer stabilizing brace is constructed from high strength polymer in black finish for durability and reduced weight. The integrated sling loop provides traditional sling attachment without additional hardware or mounting points. The polymer construction offers impact resistance while maintaining reduced weight compared to metal alternatives. The brace interfaces with pistol buffer tubes designed for AR-15 and AR style pistols.
This kit includes a heavy duty pistol buffer tube designed for AR-15 and AR style pistols, standard carbine buffer weighing 3 oz, AR-15 carbine recoil spring in spring steel, US Tactical Mil-Spec receiver end plate with phosphate finish for corrosion resistance, and castle nut in black. The pistol buffer tube configuration supports pistol brace attachment for AR-15 pistol builds. The Davidson Defense lower receiver is forged from 7075-T6 aluminum with black hardcoat anodized finish for protection against wear and corrosion. The receiver is serialized and ready for federal firearms transfer through a licensed dealer. The AR-15 lower parts kit includes all internal components needed for lower function along with ambidextrous safety selector.
Follow safe handling and manufacturer instructions. Ensure compliance with all applicable laws. Lower receiver is serialized and subject to federal firearms transfer requirements through a licensed dealer. Verify compatibility of ambidextrous bolt catch with your specific upper receiver and bolt carrier group before installation.
