The Fusion receiver is machined from 6061-T6 aluminum and hard-anodized clear, giving a durable, corrosion-resistant finish while keeping weight low. Its integral 20 MOA Picatinny rail provides immediate optics mounting without additional bases.
A 12.5-inch carbon-fiber-wrapped stainless barrel delivers rimfire accuracy with rapid heat dissipation. The barrel is threaded 1/2-28 TPI for suppressors or muzzle devices and maintains tension for consistent point of impact.
The 10-inch free-float aluminum handguard offers ample M-LOK slots plus an Arca dovetail, allowing users to attach bipods, tripod clamps, or other accessories exactly where needed without adding unnecessary weight.
A single-stage trigger, right-side cylindrical charging handle, and Magpul MOE pistol grip (Flat Dark Earth) give familiar AR ergonomics. The skeletonized chassis keeps the pistol SBR-ready for those who choose to register and add a stock.
Compatibility with Ruger 10/22 components means owners can tap into a vast aftermarket for magazines, triggers, and internals, tailoring the pistol to match their specific shooting style.
