  • Product Description

    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.

    This heavy version of the large-frame VMOS carrier includes one steel and two tungsten weights, which can be exchanged for lighter steel weights. Package includes carrier, and instruction sheet. Requires DPMS-pattern bolt, firing pin and cam pin.

    Features:

    • Enhanced tunability of operating system
    • Guaranteed reliability of difficult configurations
    • Overcomes all fouling build-up
    • Roller-burnished bore for frictionless operation
    • Rock-hard QPQ finish provides remarkable natural lubricity
    • Extremely smooth cycling with proper lubrication
    • Increased bearing surfaces for slower wear and longer component life
    • Longer cocking pad for optimal reliability
    • Additional forward assist serrations for one full inch of travel

    Compatibility:

    • The large-frame VMOS™ carrier uses the same steel and tungsten weights as GEN 2 Silent Captured Spring units. Only the forward two masses are reconfigurable. The rear-most steel mass cannot be exchanged.
    • This carrier will not cycle with a standard buffer retainer plunger installed and should be used only with a Silent Captured Spring.
    • Because the JP Law Tactical Folder Silent Captured Springs require use of a buffer retainer plunger to work, they are also not compatible with this VMOS™ bolt carrier.
