• Builders who need ambidextrous controls for either-hand operation
• Riflemen prioritizing accuracy with heavier projectiles via the 1:10 twist

Mid-Length Gas System Balance

The mid-length gas system strikes a balance between the shorter carbine and longer rifle configurations. It cycles reliably while reducing felt recoil compared to rifle-length systems. The stainless steel gas tube resists corrosion, and the micro low-profile gas block keeps the rail system clean and unobstructed.

Freefloat Handguard and Mounting Flexibility

The 19-inch freefloat handguard isolates the barrel from external pressure, which helps maintain consistency shot to shot. MLOK slots give you mounting flexibility for accessories. Quad rails at the front provide traditional rail space if you prefer that mounting method. Ambidextrous QD points at front and rear let you secure a sling from either side.

Premium Nitride Bolt Carrier Group

The Recoil Technologies nitride BCG handles .308 Win, 6.5 Creedmoor, and .243 Win interchangeably, giving you platform flexibility down the road. Nitride finish resists corrosion and reduces wear on internal components compared to bare steel.

Complete Lower Parts Kit and Buffer System

This kit includes a Recoil Technologies .308 mil-spec lower parts kit, eliminating the need to source individual trigger components, hammer, disconnector, and selector parts separately. The AR-10 carbine extra-power buffer spring is 17-7 stainless steel and made in the USA, designed to handle the heavier recoil impulse of .308 Win.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Lower receiver not included. BCG and charging handle are included in this full build kit.
