We took the rifle chassis to the next level with our XLR Carbon chassis system. Lightweight, strength, and modern style best describe the Carbon chassis. Its edgy look does not lose form to function as it utilizes our multi-point radial cut inlet for optimum accuracy. The 15.5" octagon shaped carbon fiber handguard is vented to provide uniform barrel cooling as well as M-LOKâ„¢ accessory mounting locations. The 6061 T-6 billet aluminum receiver block has been skeletonized to reduce weight and add style. As with all XLR chassis, the Carbon chassis is a direct bolt-on application with no gunsmithing or setup required by the user. The integrated detachable magazine system enables the use of AICS style detachable magazines.
