The Engage tactical pistol grip (EPG16) provides a combination of fit and function unparalleled by the originally supplied M16/AR15/M4/HK416 pistol grip. The finger swells are textetured and the grooved backstraps provide a positive grip surface with wet or gloved hands. There is a secure watertight storage compartment with plug retention for one handed storage access. A customizable storage sled with quick access tab diminishes all rattle.
