Spike's Tactical ST-15 Crusader 5.56 NATO Custom AR-15 Rifle – 16" Threaded Barrel, Skeletonized M-LOK Handguard, Crusader-Themed Engravings
Spike’s Tactical built the ST-15 Crusader to stand out, and this custom example goes a step further with a 15-inch Battle Arms Development skeletonized M-LOK handguard and faith-inspired selector markings. Chambered in versatile 5.56 NATO, it combines a forged 7075-T6 aluminum receiver set, mid-length gas system, and government-profile 16-inch barrel for reliable performance in a lightweight, maneuverable package. Laser-etched “Zombie / Killer” dust-cover art and a knurled thread protector add finishing touches that make this rifle both functional and visually distinctive.

The Crusader-marked lower receiver features selector legends in both English and Latin—“WAR / GOD WILLS IT / PEACE” on the right side and “BELLUM / PAX PACIS / DEUS VULT” on the left—along with a Crusader shield logo that ties the theme together. These factory engravings are crisp and deeply cut into the anodizing for long-term durability.
A mid-length gas system balances recoil impulse and reliability, while the government-profile 16-inch barrel is threaded 1/2x28 and protected by a knurled cap, ready for the muzzle device of your choice. The bright, sharp bore confirms minimal round count.
The lightweight 15-inch Battle Arms Development handguard is machined from 6061-T6 aluminum, skeletonized to reduce weight, and offers full-length M-LOK slots for straightforward accessory mounting. Integrated top rail sections align seamlessly with the upper receiver for continuous optics placement.
An adjustable six-position polymer stock lets you fine-tune length of pull, measured at 10.5 inches on the shortest setting. The rifle retains a classic A2 pistol grip for a familiar, secure hold.
