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 MOE RL carbine stock in black reinforced polymer fits directly onto the Mil-Spec carbine buffer tube and closes out the rear end with an adjustable length of pull, an integrated sling slot for sling attachment without additional hardware, and the slimmer and lighter body profile of the MOE RL variant compared to the standard Magpul MOE. The all-black finish across both the lower receiver and the Magpul MOE RL stock gives this lower kit a clean and consistent exterior from receiver to stock.
