The C XV series combines Core-15’s mil-spec foundation with upgraded components. Forged 7075-T6 receivers wear a Type III hard-coat anodized finish for durability and corrosion resistance.
A 16-inch chrome-moly steel barrel is nitrided for extended service life and threaded 1/2-28 TPI, ready for muzzle devices or suppressors. Direct-impingement operation keeps parts common with standard AR-15 patterns.
The factory Midwest Industries free-float aluminum handguard removes barrel contact, helping maintain accuracy while adding M-LOK slots, picatinny rail sections, and quick-detach sling sockets. A single-point QD end-plate offers additional sling options.
Furniture is mission-oriented: a six-position collapsible stock sets length of pull as short as 10.25 inches, and an Israel-made FAB-Defense AGR-43 grip improves control with an ergonomic, textured profile.
With its early “GTOC” serial, clean bore, and turnkey accessory setup, this Core-15 C XV stands out for collectors and shooters seeking a dependable, feature-rich AR-15.
