When mounted to your existing bolt catch, the Phase 5™ Extended Bolt  Release v1 (EBRV1) helps clear jams and double feeds efficiently during  magazine reloads while allowing faster operation. The release feature  allows the shooter to swipe the toggle in the downward motion with the  trigger finger to release the bolt and chamber the next round, greatly  decreasing reload time.
Rugged construction for increased durability even under extreme conditions.
