Lower Receiver

The Spike's Tactical Calico Jack lower receiver is a forged 7075-T6 aluminum receiver finished to MIL-A-8625F Type III Class 2 hard coat anodize standards in black. The Mil-Spec pattern receiver carries multi-caliber markings and the Calico Jack-specific selector markings of Parley, Argg, and Plunder engraved on both sides of the receiver body. The receiver accepts standard Mil-Spec AR-15 components throughout the lower.

Lower Parts Kit and Buffer System

The complete Mil-Spec AR-15 lower parts kit covers the full internal lower component group, including the fire control group, magazine catch, bolt catch, and all associated pins and springs. A Mil-Spec A2 style pistol grip in black covers the grip interface. The Mil-Spec heavy-duty AR-15 6-position carbine buffer tube in aluminum, standard AR-15 carbine recoil buffer at 3 oz., and standard AR-15 carbine recoil spring made in the USA form the complete buffer system at the rear of the lower. The US Tactical AR-15 and M16 Mil-Spec receiver end plate and AR-15 carbine castle nut lock the buffer tube down cleanly at the rear of the receiver. The Magpul DT carbine stock in FDE reinforced polymer made in the USA fits directly onto the Mil-Spec carbine buffer tube and closes out the rear end with an adjustable length of pull secured by a dual tension auto-engaging friction lock controlled by a single ambidextrous adjustment lever, a slim ergonomic profile with a sloping cheek weld, a non-slip rubber butt pad with optimized curvature, a rotation-limiting integral QD sling socket, and a rear 1.25-inch sling loop that together give the builder two sling attachment options built directly into the stock body. The DT is compatible with CTR cheek risers on fully extended stocks or rifles without rear-facing charging handles. The FDE color of the Magpul DT stock provides a contrasting finish against the black anodized lower receiver, giving the lower build a two-tone exterior from receiver to stock.
