Spike's Tactical Crusader, Multi-Caliber, Enhanced LPK, Magpul MOE Grip & CTR Stock, Black, AR-15 Complete Lower The Spike's Tactical Crusader complete lower receiver is a fully assembled AR-15 lower that is ready to pair with the upper of your choice. It is built on Spike's forged Crusader receiver, with the Crusader logo on the magwell and Pax Pacis, Bellum and Deus Vult selector markings, and it is assembled with Spike's Enhanced Lower Parts Kit, a Magpul MOE grip and a Magpul CTR stock, all in black. Every Spike's complete lower is assembled, inspected and tested by the Spike's Tactical lowers department. The specifications and tolerances are the same as the lowers Spike's uses on its own complete rifles, so you get a factory-built lower without sourcing and fitting the parts yourself. The receiver is forged from 7075-T6 aluminum with a MIL-A-8625F Type III Class 2 hard coat anodized finish and is marked Multi for caliber. Add a complete upper in 5.56 NATO/.223 Rem, .300 Blackout or another AR-15 caliber and you have a complete rifle.

Shipping FFL required (serialized receiver) Enhanced Lower Parts Kit Spike's Enhanced Lower Parts Kit upgrades the parts that matter most on a lower. The Spike's Tactical Battle Trigger replaces a standard mil-spec trigger, the Gen 2 billet trigger guard gives more room for a gloved finger, KNS anti-rotation pins keep the trigger and hammer pins from walking, and the ambidextrous safety can be worked from either side of the rifle. Magpul Furniture The lower comes with a black Magpul MOE grip and a black Magpul CTR stock. The CTR rides on a 6-position mil-spec buffer tube with a castle nut and staked latch plate, so the stock stays secure while you adjust length of pull. A 17-7 stainless buffer spring and Spike's ST-T2 buffer complete the recoil system. Engraving Note The Crusader complete lower does not include the bible verse engraving. Spike's Tactical reserves that engraving for its complete Crusader rifle. Spike's complete lowers are built to order.

The forged Crusader lower receiver fully assembled with Spike's Enhanced Lower Parts Kit (Battle Trigger, Gen 2 billet trigger guard, KNS anti-rotation pins, ambidextrous safety), a black Magpul MOE grip, and a stock assembly with a 6-position mil-spec buffer tube, castle nut, staked latch plate, 17-7 stainless buffer spring, ST-T2 buffer and black Magpul CTR stock. No upper receiver is included. Which uppers does it work with? It works with standard AR-15 upper receivers. Because the receiver is marked Multi, you can run 5.56 NATO/.223 Rem, .300 Blackout or other AR-15 calibers with the matching upper and magazines. Is the safety ambidextrous? Yes. The Enhanced Lower Parts Kit includes an ambidextrous safety selector. What buffer does it use? It comes with Spike's ST-T2 buffer and a 17-7 stainless buffer spring in a 6-position mil-spec buffer tube. What does it weigh? 1 lb. 15 oz. as built. Do I need an FFL to buy it? Yes. The lower receiver is the serialized part of the rifle and is legally a firearm, so it ships to your local FFL dealer for transfer. See how buying a firearm online works.
