Arriving complete with a true left-handed Bolt Carrier Group (BCG), full Mil-Spec lower parts kit, and an adjustable rifle buttstock assembly, this kit strips the technical guesswork out of converting your stripped lower into a high-performance match rifle.

True Southpaw Safety and Sightline ClarityStandard right-handed uppers force left-handed operators to shoot straight through a cloud of high-pressure exhaust gas, unburnt powder, and flying spent casings. This mirrored left-ejection receiver routes all debris entirely to the left, keeping your path of vision flawless so you can maintain total downrange situational awareness.
Lock Into Your Optic with Non-Reciprocating ControlTraditional rear-charging handle systems force you to break your cheek weld and move away from your target to clear a malfunction or cycle the weapon. This premium system upgrades management to a fluid, side-charging interface where the handle remains completely stationary while firing. You get clean, optimal clearance for large tactical optics and the ability to track your shots seamlessly without moving parts cycling near your support hand.
Match-Grade Stainless Steel BallisticsStepping up to the 18-inch barrel configuration unlocks a massive velocity and trajectory advantage. 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.
