Geissele Hi-Speed National Match Trigger Set - Large Pin 05-150 covers three distinct trigger configurations in a single purchase — Service Rifle, Designated Marksman Rifle, and Match Rifle spring sets are all included. This Geissele National Match trigger is fully adjustable. First and second stage weight distribution, total pull weight, over-travel, and sear engagement can all be tuned to the shooter's preference rather than locked to a fixed factory setting. The Service Rifle configuration meets CMP's minimum 4.5 lb pull weight requirement and is approved for National Trophy, NTIT, and Excellence in Competition matches. The DMR setup runs 3.0-5.1 lbs total for tactical and military use where pull weight isn't regulated, while the Match Rifle spring set drops as low as 1.9-3.4 lbs for pure precision work. A full-power hammer spring imparts more kinetic energy into the firing pin, producing more consistent primer ignition — especially useful with AR-10 based platforms or less common cartridges.
