Combat Armory CA-15 300 Blackout Rifle 16" M-LOK

Combat Armory CA-15: Purpose-Built for Subsonic Performance

The Combat Armory CA-15 represents a thoughtful approach to modern rifle design. Built entirely from billet 7075-T6 aluminum and finished with hard-coat Type III anodizing, this rifle delivers the durability expected of a Mil-Spec platform while maintaining the precision tolerances that serious shooters demand.

Barrel and Gas System

The 16-inch 4140 chrome moly vanadium barrel is finished in Melonite and chambered in 300 Blackout—a cartridge that excels in both suppressed and unsuppressed applications. The carbine-length gas system pairs with a low-profile .750 gas block for reliable cycling. An A2 flash hider comes standard.

Ergonomics and Modularity

Key features include:

• Free-float 15" M-LOK handguard for superior accuracy and accessory mounting
• Ambidextrous safety selector for both left and right-handed shooters
• MIL-STD charging handle and forward assist
• Pistol-length buffer tube configuration
• 1/2x28 muzzle threads for suppressor compatibility

What You Get

This is a complete, ready-to-shoot rifle. Every component meets military specifications, and the rifle ships with a 30-round magazine. Whether you're building a precision rifle or a tactical platform, the CA-15 provides a solid foundation.

The 300 Blackout chambering makes this an excellent choice for hunters, sport shooters, and those seeking a versatile, quiet-capable platform.
