22 ARC Platform and Caliber Focus

The 22 ARC is a modern intermediate cartridge designed specifically for AR-15 platforms. It delivers velocity and ballistics between 5.56 NATO and 6.5 Grendel, making it ideal for medium-range hunting and precision shooting. The 1:7 twist rate in this barrel is optimized for 22 ARC projectiles, ensuring stability across the full range of available ammunition weights. This kit uses standard AR-15 upper and lower receiver dimensions, so it integrates seamlessly with existing AR-15 accessories and components.

Freefloat Handguard and Accuracy

The 17-inch M-Lok handguard is mounted independently from the barrel, which means barrel harmonics aren't affected by grip pressure or shooting position. This design reduces point-of-impact shift and improves consistency shot to shot. The quad rail sections at the front provide mounting points for tactical accessories, and the integrated QD mounts on both the handguard and stock give you flexibility for sling attachment and weapon positioning.
