Recommended Upgrade:

RC-QD Retainer Cover & QD Sling Mount – For handguards with a sling loop cut, we recommend adding the RC-QD Retainer Cover and QD Sling Mount. This upgrade reinforces the cutout, restoring handguard rigidity, protecting against burns from the steel handguard retainer, and providing a modern QD sling attachment point for convenience.

HG-RM Rigid Mount – If you're mounting a laser or other zero-dependent device, the HG-RM Rigid Mount is essential. This upgrade anchors the handguard to the barrel, creating a solid mounting platform for accessories. It also enhances the overall feel of the handguard, providing a more rigid experience. Multiple sets can be used for customized rigidity. Note: Adding this accessory eliminates the free-float design, which may impact long-range accuracy.
