ATOM Chassis

  • The ATOM rifle and pistol chassis system!

    Create the ultimate rifle or pistol chassis with XLR's new ATOM chassis. Designed with everyday shooters and hobbyists in mind, the ATOM makes for a great rifle chassis or bolt-action pistol chassis. With its compact, lightweight, and modular design the ATOM excels as your everyday truck gun or lightweight mountain rifle.

    The all-new ATOM features the same built-in bubble level and machined in RRS 1.5" dovetail (Arca-Swiss) in the forend as the Element 4.0 chassis.

    Precision machined bolt-action rifle and pistol chassis

    Machined from solid 6061 T-6 billet aluminum, the ATOM chassis has the same multi-point radial cut inletting that eliminates the need for traditional V-Block or Glass Bedding. This style of 'bedding' has proven to increase accuracy and repeatability beyond traditional bedding or inletting methods. Mounting your action into our rifle or pistol chassis only requires a torque wrench and few minutes of your time.

    ** Expected extended lead time due to high product demand. Lead times are 15-20 week for all chassis orders. We appreciate your patience. **
