The Badger Ordnance IMUNS installs into any Accuracy International Chassis 2.0 (except AS 50’s), replaces the current bipod mounting block and allows the use of clip on night vision devices such as the A/N PVS-22, A/N PVS-24, A/N PVS-27 or other devices like thermal imagers or fusion devices. The IMUNS has a side accessory rail that allows the use of laser aiming devices such as the ATPIAL/DBAL and all other issued aiming lasers. The mount retains the bipod socket for the AI bipod and also allows for the use of a Harris style bipod. No permanent modification is required. Weight: 12.0 Oz.
