ArmaLite M153GN18 M-15 Competition 223 Rem 18" Barrel 30+1

The ArmaLite M153GN18 M-15 Competition delivers precision shooting performance with an 18-inch barrel optimized for accuracy and velocity retention. This competition-focused rifle combines ArmaLite's proven M-15 platform with specialized components that enhance long-range capability. Built for serious competitors who demand consistent shot placement and reliable function through extended shooting sessions.

What Makes This Different

The 18-inch barrel length strikes an optimal balance between velocity and maneuverability, providing approximately 150-200 fps more velocity than standard 16-inch barrels. The hard coat anodized receiver finish resists wear and corrosion better than standard mil-spec coatings. Competition-grade components throughout the rifle reduce variables that affect accuracy, while the Luth-AR MBA-1 adjustable stock allows precise length of pull customization for consistent cheek weld and sight alignment.

Key Features
