Spike's Tactical Crusader Lower Receiver

The Crusader STLS022 is a hard coat anodized aluminum lower receiver with distinctive Crusader shield engraving and bilingual selector markings. The receiver accepts standard AR-15 pattern magazines and works with standard mil-spec fire control components. Multi-caliber marking means it's ready for any upper assembly you pair with it.

You get the complete fire control group with curved mil-spec trigger, hammer, disconnector, safety selector, all required pins, detents, springs, magazine catch assembly, bolt catch assembly, trigger guard, and buffer retainer. A mil-spec A2 pistol grip in black rounds out the lower receiver components.

Pistol Buffer System and Brace

The Davidson Defense pistol receiver extension is precision-machined aircraft-grade aluminum with type II anodized finish. It's 7.375 inches long and accepts standard carbine or pistol-weight buffers. The kit includes a standard 3-ounce carbine recoil buffer with polymer impact pad and a made-in-USA carbine recoil spring. The Gauntlet Arms polymer stabilizing brace mounts directly to the receiver extension in a fixed position and includes an integrated sling slot for attachment options.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Lower receiver not included. Verify brace legality in your jurisdiction before purchase and use.
