VBS

Image

Variable Buffer System

Description PRICE
The VBS is a Variable Buffer System consisting of three buffer spacers. When installed in the MAX-11k, the rate of fire can be easily changed to 750, 950 or 1140 RPM.

The 750 RPM rate of fire is achieved by installing a single buffer spacer, two buffer spacers achieve a rate of fire of 950 RPM and three increase the rate of fire to 1140 RPM.

These rates of fire were achieved with Winchester 115 gr. full metal jacket, round nose ammunition. Ammo that has heavier or lighter bullet weight or is more or less powerful will have a different rate of fire.

While the VBS was designed with the intention of being used with our MAX-11k upper receiver, it can also be used with a stock M-11/9 to vary the rate of fire.

The VBS easily installs on your bolt assembly by simply installing it between the rubber buffer and the back of the bolt assembly. It is securely held in place with the ejector rod.

The VBS-3 is priced at $30.00 and includes three spacers. Individual spacers can be purchased for $10.00 each. #420
