Key Features

Premium Match Stainless Steel: 16-inch barrel machined from high-grade stainless steel to deliver superior concentricity, enhanced throat life, and tight, sub-MOA precision groupings.
Versatile 223 Wylde Chambering: Specially designed hybrid chamber profile optimizes accuracy and pressure curve dynamics for both .223 Remington and 5.56x45mm NATO cartridge selections.
All-In-One Hardware Package: Consolidates your rifle project by grouping a premium mil-spec lower parts kit, complete standard BCG, charging handle, and an adjustable stock and buffer tube system under a single part number.
Smooth Mid-Length Gas System: Calibrated with a low-profile gas block to supply excellent dwell time, lowering component wear and softening the overall recoil impulse for rapid, flat follow-up shots.
Fast 1/7 Twist Rifling: Precision-rifled profile engineered to provide exceptional rotational stabilization for heavy grain tactical and match-grade projectiles (62gr, 69gr, and 77gr).
Free-Float Slim M-LOK Handguard: Enhances intrinsic accuracy by isolating barrel harmonics, providing an expansive top Picatinny rail and clear M-LOK attachment slots for grips, lights, or bipods.
