The Gray Ops Thumb Rest/Thumb Rail is designed for the popular MPA BA Chassis system and allows shooters to use their off hand to help stabilize the rifle in improvised shooting positions. Designed to go on the left side of the chassis, the Gray Ops Thumb Rest provides and ergonomic position for shooters to apply pressure to the front of the MPA chassis, while the Thumb Rail replaces the picatinny rail located on the top of the MPA Chassis' night vision bridge. Combined, the Gray Ops Thumb Rest and Rail give the shooter multiple options to help secure and steady the rifle when faced with barricades and improvised shooting positions.
