Perfect For

• Shooters building a mid-range precision or tactical .308 platform
• Hunters seeking a reliable intermediate-distance rifle setup
• Builders who want a complete upper and lower assembly solution
• Those prioritizing accuracy through freefloat barrel design

Precision-Focused Upper Assembly

The 18-inch barrel paired with the freefloat M-Lok handguard creates a stable platform that isolates the barrel from handguard contact. This design minimizes harmonic interference and supports consistent shot placement. The 1:10 twist rate handles standard .308 Winchester loads effectively across a broad range of bullet weights.

Complete Lower Assembly Ready

This kit ships with the Recoil Technologies lower parts kit, a 6-position buffer tube, 17-7 stainless steel buffer spring, and a collapsible stock with integrated cheek riser. The mil-spec heavy-duty buffer tube and extra-power buffer spring manage recoil impulse reliably. All components assemble into a functional lower receiver once mated with a stripped LR-308 lower.

Mid-Length Gas System Reliability

The mid-length gas system uses a .750-inch gas block and stainless steel gas tube sized for smooth bolt carrier cycling. This configuration balances reliability with manageable recoil and is optimized for standard .308 Winchester pressures. The Guntec multi-port compensator at 5/8x24 thread helps manage muzzle rise during rapid fire.

Billet Upper and Premium BCG

The billet LR-308 upper receiver features DPMS low-profile dimensions and Type III hardcoat black anodize for durability. The Recoil Technologies nitride bolt carrier group is rated for .308 Win, 6.5 Creedmoor, and .243 Win, providing flexibility if future caliber changes are considered.
