The Geissele Hi-Speed Service Rifle trigger is designed for High Power Service Rifle competition. It is an approved trigger for use in NRA and CMP High Power matches including sanctioned competitions such as Excellence In Competition and the National Trophy matches. The Service Rifle trigger’s adjustability and exclusive 5-coil trigger spring allows for a heavier 1st stage pull weight and lighter 2nd stage weight to give outstanding control and precision while still meeting the minimum trigger weight requirement of 4.5 lb.
