The Geissele Hi-Speed Match Universal is a fully adjustable two-stage match trigger for AR-15 and M4 pattern rifles, fitting Mil-Spec lower receivers that use .154 in trigger and hammer pins.
The match shooter's laboratory — Geissele's Hi-Speed Match Universal is a two-stage trigger you tune to the discipline.
The Geissele Hi-Speed Match Universal (05-181) is the adjustable flagship of the line: a true two-stage match trigger whose first-stage weight, second-stage weight, sear engagement and overtravel can each be tuned to your discipline and preference. The Universal configuration is the versatile centre of the Hi-Speed family — equally at home in service rifle, precision and long-range match builds.
Adjustability at this level demands Geissele's machining, and gets it: hardened, precision-ground components hold your settings shot after shot, and the pull quality across the adjustment range stays glassy. This is the trigger for shooters who know exactly what they want a break to feel like.

What the Hi-Speed Match Universal fits
Drop-in fit for AR-15/M4 pattern lower receivers with Mil-Spec .154 in trigger and hammer pins, including UK straight-pull AR-15 builds, where a tunable two-stage break rewards the deliberate, aimed shooting the platform is used for here. Large-pin receivers are not compatible — confirm your pin size before ordering. Set-up rewards patience: tune at the bench one adjustment at a time with the rifle unloaded, verify sear engagement and safety function, then confirm on the score sheet.
