The JPBC-4BA is a JP Enterprises low mass bolt and carrier for .308 AR-pattern rifles. A lighter carrier reduces recoil impulse and muzzle movement, which helps with fast follow-up shots. It is aimed at competition and tuned AR-10 builds. Compare it with your existing part or the manufacturer's parts diagram to confirm it matches your firearm before ordering.
