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.
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.

£5 tracked UK delivery on every order via Royal Mail Tracked 24. Our products are ordered in from the manufacturer rather than held in UK stock, so please allow 7 to 10 business days (Monday to Friday, excluding bank holidays) from the date of your order for it to reach you. Tracking details are emailed on dispatch. UK delivery only.

It is a drop-in fit for AR-15/M4 pattern lower receivers using mil-spec trigger pins. Some receivers use large-pin or otherwise non-standard holes, so confirm your pin size before ordering. If your lower is an unusual pattern, <a href="/pages/contact">contact us</a> with the make and model and we'll check.
This is Geissele's fully adjustable two-stage match trigger: pull weight, sear engagement and overtravel can all be tuned rather than being set at the factory. That makes it the one to choose if you want to dial the trigger to a discipline or to your own preference over time. Fixed-weight models such as the SSA family are simpler and need no setting up.
Work one adjustment at a time, in small increments, and function-check the rifle thoroughly after every change, including safety and hammer-follow checks with the bolt cycled by hand. Only adjust with the rifle unloaded and the magazine out. If you are not confident carrying out those checks, have a gunsmith set it up for you.
If you compete or shoot precision and want to fine-tune the break, the adjustability earns its keep; for a general-purpose carbine, a set two-stage is usually easier to live with. Have a look at the wider <a href="/collections/geissele-automatics">Geissele Automatics</a> range to compare, and our <a href="/blogs/buying-guides/ar-15-trigger-guide">AR-15 trigger guide</a> explains single versus two-stage in plain terms. Nothing extra is needed to install beyond your existing trigger pins if they are in good condition.
Triggers are dispatched from the United Kingdom with £5 tracked UK delivery in 7–10 business days, and tracking is emailed to you when it ships. If it turns out to be the wrong fit for your lower, see our returns policy or <a href="/pages/contact">contact us</a> and we'll help sort it.
