J P Enterprises Ar-15 Low Mass Bolt Carrier Assembly. Lightweight, stainless steel bolt carrier has significantly lower reciprocating mass than a standard mil-spec carrier for softer recoil impulse on competition rifles. Helps limit felt recoil to get you back on target for fast follow-up shots. Lightening cuts reduce weight without sacrificing strength, and the forward assist serrations have been omitted for competition use. Extra-wide carrier rails have extra bearing surface to improve bolt alignment and reduce wear. Comes with carrier key installed and staked, and features a dust cover notch. For best performance and to minimize impact wear, use only in rifles with J.P. Low-Mass Recoil Buffer, Speed Hammer, and Reduced-Power Spring Kit, all

J P Enterprises 308 Ar Enhanced High Pressure Bolt Completion Group.

Some rifle manuals even record the maximum recommended load data beyond the functional range of these rifles. Unfortunately, these issues will persist until the manufacturers of ammunition realize that an AR platform requires a unique pressure curve to allow for both accuracy and reliability. Manufactured to the exacting standards of our standard bolt offerings, the High Pressure EnhancedBolt des
