.223 Wylde Caliber Advantage

The .223 Wylde chamber is designed to safely fire both commercial .223 Remington and military 5.56 NATO ammunition. This gives you flexibility in what you can shoot without sacrificing accuracy or safety. The 1:7 twist rate stabilizes a wide range of bullet weights, from lighter varmint rounds to heavier 77-grain match ammunition.

Free-Float Handguard Design

The 12-inch KeyMod handguard floats freely from the barrel, meaning the barrel doesn't contact the handguard at all. This isolation improves consistency shot to shot because barrel harmonics aren't affected by pressure from the rail system. The anti-rotation tabs keep the handguard locked in place without needing set screws.

Mid-Length Gas System Performance

Mid-length gas systems strike a balance between carbine and rifle-length designs. You get slightly softer recoil than a carbine system while maintaining reliability with a shorter sight radius. The micro low-profile gas block keeps your rail space clear for optics and accessories without adding unnecessary height.

USA Manufacturing

Key components like the bolt carrier group and recoil spring are made in the USA. The barrel, gas tube, muzzle brake, and upper receiver meet quality standards for reliable long-term use.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Lower receiver not included.
