From the manufacturer

Reduced-weight bolt/carrier assembly helps tame felt recoil on a JP or DPMS or Remington AR-style .308 rifle (LR-308 pattern only). Carrier features the same type of weight-reducing cuts found on the original JPBC-3 AR-15 bolt carrier to give the same benefits your .308. Wide carrier rails have extra bearing surface to improve bolt alignment and reduce wear. Comes with a complete JP EnhancedBolt(TM) (also available separately), designed to stand up to high-heat, high-impact use. Carrier key is already installed and staked. Available with QPQ or polished stainless finish. Mfg: J P Enterprises
