The new VMOS bolt carrier from JP Enterprises is a modular carrier that gets rid of the necessity to change the mass of your Silent Captured Spring, or having to tune your adjustable gas block. This carrier is made from 416 stainless steel which is a very rugged durable steel, on top of this the VMOS carrier has been Melonite treated. This treatment heightens the carrier's lubricity, generally meaning less preventative maintenance. This carrier will allow you to tune the weight/mass to perform perfectly with your setup. This is the standard weight/low mass version of the BC-7, as it allows you to go with a weight similar to the LMOS up to a standard weight. The BC-7H2 allows you the same tuning features, but with Tungsten weights for a higher mass. This is perfect for shooting suppressed or a hot cartridge like a 6.5 Creedmore.
