Complete Kit for Seamless Conversion

The UXR Conversion Kit includes a precision-machined 14.5″ barrel with a 1:7 twist rate optimized for stabilizing heavy 300 Blackout projectiles. The kit comes with a properly tuned gas system, ensuring reliable cycling with both subsonic and supersonic ammunition without requiring adjustments.

Superior Engineering and Durability

Primary Weapons Systems is renowned for their innovative firearm solutions, and this conversion kit exemplifies their commitment to quality. The barrel features a nitride-treated surface for enhanced corrosion resistance and extended barrel life. The gas block is securely pinned to prevent shifting during rapid fire, while the gas tube is constructed from high-grade stainless steel for maximum durability under sustained use.

Why Choose 300 Blackout?

The 300 AAC Blackout cartridge offers significant advantages over traditional 5.56 NATO rounds. With proper ammunition selection, you can achieve:

• Excellent terminal performance on medium game
• Reduced noise signature when using subsonic ammunition
• Minimal over-penetration concerns for home defense scenarios
• Compatibility with standard AR-15 magazines and lowers
• Effective performance from shorter barrels without excessive muzzle blast

Technical Specifications

The 14.5″ barrel length strikes the perfect balance between maneuverability and ballistic performance. When paired with a muzzle device that brings the overall length to 16″ or more, this configuration remains compliant with federal regulations while providing excellent velocity retention. The 1:7 twist rate ensures optimal stabilization for bullets ranging from 110 to 220 grains, making this conversion kit versatile enough for any 300 Blackout application.

Installation and Compatibility

This conversion kit is designed for straightforward installation on most mil-spec AR-15 platforms. Basic armorer’s tools and mechanical aptitude are recommended for proper installation. The kit maintains compatibility with standard AR-15 handguards, allowing you to retain your preferred rail system or upgrade to a new one without compatibility issues.
