Spikes STR5525M2D Crusader 223 Rem,5.56x45mm NATO 14.50" No Magazine Black Hard Coat Anodized 6 Position Magpul CTR Stock

The Spikes STR5525M2D Crusader in .223 Remington/5.56x45mm NATO is a purpose-built fighting rifle engineered for operators, law enforcement, and serious enthusiasts who demand reliability under demanding conditions. With a 14.5-inch chrome-moly vanadium barrel featuring chrome lining and mil-spec phosphate coating, this carbine delivers the ballistic efficiency of the 5.56 platform in a compact form factor optimized for close-quarters and mid-range engagement.

The upper receiver is machined from 7075-T6 aluminum alloy and topped with a free-floating 12-inch M-LOK rail that accommodates modern optics, lights, and other tactical accessories without binding. Pre-mounted Magpul MBUS backup iron sights provide co-witness height compatibility with most combat optics. The lower receiver includes a low shelf design with RDIAS compatibility for those who require it, along with quick-detach attachment points for slings and support gear. The mid-length gas tube features black nitride coating inside and out, enhancing corrosion resistance during extended field use. The Magpul CTR stock in the 6-position configuration allows length-of-pull adjustment for different body armor profiles, gear configurations, and shooter preferences. Hard coat anodize finish protects the aluminum surfaces from corrosion and abrasion typical of patrol, training, and tactical environments.

This rifle serves law enforcement patrol units, military support roles, and civilian operators who prioritize a balanced, lightweight platform without compromising durability or modularity. The 14.5-inch barrel with 1/2"x28 threading accepts common muzzle devices—flash hiders, compensators, and suppressors—enabling users to tailor the carbine for specific mission profiles. At 13.8 pounds, the Crusader maintains reasonable weight for extended carry while delivering the accuracy and ergonomics expected from precision-manufactured AR-platform components.
