Our original and most widely used chassis, the Evolution offers a lightweight yet durable stock solution for most popular receivers on the market. Its new octagon MLOK™ handguard allows a structurally rigid forend with minimal weight to help offset barrel weight. Will accept any MLOK™ accessories. Cooling vents provide uniform cooling for the barrel during long strings of fire. The Evolution chassis is machined from solid 6061 T-6 aluminum allowing direct bolt-on application with no gunsmithing or setup required by the user. A multi-point radial cut inlet allows the receiver to sit in the chassis stress-free for utmost accuracy (no V-block). The integrated detachable magazine system allows the use of AICS style detachable magazines.
*WEIGHT: Starts at 34 ounces. Varies slightly based on inlet. (Weight does not include grip or buttstock)
