Cycling problems? The VMOS brings the discipline your rifle needs.
For difficult setups like suppressed rifles and exotic caliber chamberings, some degree of mass regulation is required for optimal performance. This is especially true in the absence of an adjustable gas block. Residual gas and excessive fouling can grind your rifle to a stop.
One size never fits all when it comes to gas-operated rifles. The Variable Mass Operating System (VMOS) carrier ensures reliability through additional reciprocating mass but provides more custom tunability. Combined with our Silent Captured Spring, multiple masses are exchangeable to perfectly tune your operating system weight.
The EnhancedBolt is compatible with any AR-15 platform using a Mil-spec bolt carrier and sub-components.
Package includes carrier, bolt assembly, cam pin, firing pin, firing pin retainer pin and instruction sheet.
