Overview
JP Enterprises Small Frame Variable Mass Bolt Carrier Group (BCG) with Enhanced Bolt.
Designed for gas-operated AR-15 platforms, including difficult setups such as suppressed rifles and exotic caliber chamberings, where mass regulation can improve reliability.
The Variable Mass Operating System (VMOS) carrier provides additional reciprocating mass and tunability. Combined with JP’s Silent Captured Spring, multiple masses are exchangeable to tune operating system weight.
