The Geissele Hi-Speed National performance trigger comes with 3 sets of springs referred to as: Service Rifle (for NRA High Power Service Rifle competition shooting), Designated Marksman Rifle (for tactical and combat applications) and Match Rifle.
Service Spring Set
The Geissele Hi-Speed Service spring set is designed for NRA High Power Service Rifle competition. A trigger with this specification is officially approved for shooting in National Trophy, NTIT and Excellence In Competition. One of the criteria for weapons used in these types of competitions is a minimum trigger pull weight of 4.5 pounds. The Service Rifle Trigger kit includes a 5-wound trigger spring that provides 4 pounds of resistance on the first stage. This makes the second-stage breakthrough light and precise.
DMR Spring Kit
The Designated Marksman Rifle springs are designed for tactical and military shooting. The heavier weight on the 2nd stage helps when shooting in high-stress situations.
Match spring set
Match springs dedicated to NRA High Power Rifle competitions that use tuned AR-15 carbines. With the ability to significantly reduce the trigger weight, you get excellent shot control. The full-power cocking spring ensures a certain primer pickup, regardless of the ammunition used, which is especially important when shooting elaborated ammunition.
Note: The Geissele Hi-Speed National mechanism is not compatible with Sig MPX/MCX carbines and PCC AR15/M4 weapons.
