Bolt-action accuracy. Gas-system repeatability.

Our Precision Gas System is a proprietary action that gives a semi-automatic rifle the consistency of a bolt gun. A free-float barrel and a monolithic chassis hold the point of impact fixed across long strings of fire.

Engineering

What keeps it consistent

Three subsystems hold the point of impact fixed as the rifle heats and cycles.

Free-float barrel

The first actual free-floating barrel on a gas gun, using the patented PGS System. The barrel contacts nothing but the chassis, removing the pressure points that quietly pull rounds off the point of aim.

Precision Gas System

Bolt-action consistency with gas-driven cycling, so accuracy holds across strings of fire rather than degrading shot to shot.

Monolithic chassis

A single rigid platform locks the action in place and gives every optic and accessory a true, repeatable reference.
