This new chassis system, machined from 6061-T6 billet aluminum, is the perfect start for your Ruger® 10/22® build. This is a lightweight model weighing only 12oz. Perfect to fit AR-15 style buffer tube stocks, and other AR-15 and M16 style grips and accessories. Special attention was taken to allow you to use multiple AR-15 style grips. M-Lok slots are located at 3 positions for your ability to mount whatever you want. Our chassis features a trigger group set screw, which hides in the grip to allow a secondary point to lock down your receiver and barrel. We have a free floating barrel system that allows several different barrel lengths, up to .92" diameter, and allows a maximum 1" suppressor to be used on a minimum 3" barrel.
