Lock Into Your Glass with Non-Reciprocating Side ChargingStandard rear charging handles force you to break your cheek weld, drop your shooting stance, and yank a handle right underneath your optical plane to cycle the action or clear a malfunction. This premium system features a fluid side lever that stays completely stationary while firing. This means zero moving parts near your support hand and smooth, instant manual cycling while keeping your eyes tightly locked onto your target through the optic.
Flawless Hybrid Performance via the 223 Wylde ChamberThe specialized 223 Wylde chamber brings bolt-action accuracy to a semi-automatic platform. It features a tighter, more precise throat geometry than a standard 5.56 NATO block while safely containing the higher pressure curves of military-grade ammunition. It allows you to cycle commercial .223 Remington match ammo or standard 5.56 duty rounds interchangeably with peak precision.
Match-Grade Stainless Steel PrecisionStepping up to the 18-inch barrel configuration unlocks a massive velocity and trajectory advantage over standard carbines. Machined from premium stainless steel, this barrel delivers superior structural concentricity and tight sub-MOA precision groupings. Paired with a fast 1/7 twist rate, it is perfectly optimized to rotationally stabilize heavy tactical and match-grade projectiles (such as 62gr, 69gr, and 77gr loads) across extended distances.
