Our original and most widely used chassis. The XLR Evolution chassis offers a lightweight yet durable stock solution for most popular receivers on the market. Its new octagon M-LOK™ handguard allows a structurally rigid forend with minimal weight to help offset barrel weight. The handguard will accept any M-LOK™ accessories. Cooling vents provide uniform cooling for the barrel during long strings of fire. The Evolution chassis is machined from solid 6061 T-6 billet 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.
Comes with a M Lock QD mount and M lock 6 slot rail
