Centurion Arms LLC Match Grade Competition Trigger Group gives you a smooth, consistent, two-stage pull, with a clean break and little-to-no pre- and over-travel. It’s built with a fit, finish, and attention to detail found in very few AR triggers, let alone one at this price-point.
Each Centurion Arms LLC Match Grade Competition Trigger Group is machined from hardened A2 tool steel (NOT MIM parts!) to precise dimensions, then micro polished to eliminate “creep” during the pull. Finally, the hammer and trigger in each Match Grade Competition Trigger Group gets an ultra-hard, self-lubricating Nickel Boron coating, to ensure an extremely smooth pull.
Hardened A2 tool steel hammer, trigger, disconnector
Ultra-hard Nickel Boron coating on hammer / trigger
Ultra-grade stainless steel music wire springs included
Drop-in fit in standard AR-15 lower receiver
Pins included (.153″ dia.)
Centurion Arms LLC Match Grade Competition Trigger Group has the two-stage pull preferred by precision rifle shooters. It gives you excellent control that lets you “stack” the trigger then pause before you completing the pull through the second stage.

Works.
Works as described. It's definitely a "carrot" break vs a "glass" break. Feels ALOT better then a Larue. The MBT-2S was the most gritty trigger I've ever felt. I would buy these all day long over that hot garbage.
USNice trigger for a good price.
United StatesSolid
Solid two stage- good for a duty style weapon, where you don't want to worry about an AD. Made by a top military contractor- and re-branded by quite a few companies. I have the original non-branded version (was a little cheaper). Comes with the "red" trigger spring, and a mil-spec hammer spring. I've also tried it with a mil-spec trigger spring, which did not add any noticeable weight to the total pull weight. No matter which springs you use, it's a clean crisp pull on both stages. To increase crispness- use tier 1 pins (FN, Colt, etc). Good stuff!
USNice trigger
Very nice trigger. Easy to install
USThe AST is a GREAT trigger!
Once my gunsmith installed the two I bought - one in a 24" barrel Creedmoor AR, the other in a 224 Valkyrie AR - the difference was STARK. The trigger breaks CRISP every time...and since it's NuB coated throughout it will break like that for the life of the units. Can't do better than something that is ALWAYS the same aa when you installed it!
