The JP Low Mass Operating System With HP Bolt is designed for weapon systems that have adjustable gas systems. The low mass carrier allows for a lighter recoil impulse especially when your gas system is tuned to perfection. As a complete BCG this component is cross compatible with DPMS and Armalite pattern rifles. However you should never mix the two types of parts when not buying a complete BCG. Be aware that just because this BCG comes with a high pressure bolt, it is not guaranteed to function with over pressurized cartridges.
The LMOS is compatible with both DPMS and Armalite, but you should never mix the two types of parts when not buying a complete BCG.
