XLR is a U.S. based manufacturer of world-class rifle chassis, components, and accessories. The company manufactures the renowned Element, Evolution, Carbon, and Envy chassis systems for professional shooters, tactical shooters, and hobbyists alike. All XLR chassis systems are manufactured in the U.S.A. and are machined from 6061 T-6 billet aluminum. XLR chassis feature a multi-point radial cut inlet that mirrors your receiver, creating a perfect chassis to action union. This inlet method eliminates any external stresses commonly found in traditional or v-block stocks. This style of 'bedding' has proven to increase accuracy and repeatability beyond traditional bedding or inletting methods. Mounting your action into our chassis only requires a torque wrench and few minutes of your time. What makes our chassis systems so unique is the use of our adjustable buttstocks. Renowned for their large range of adjustment and usability across numerous platforms, including AR15 style rifles. XLR buttstocks allow the shooter to truly fit their rifle to their build and shooting style. Making your shooting experience more enjoyable, accurate and repeatable.
