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.

    This trigger is Wonderful! Comparable to triggers that cost $150.00 more! I have used these on several AR15 builds and my customers are very pleased! Great job!

    WOW! I absolutely love this trigger! I recently installed it into one of my AR builds. The finish, the feel and the action of this trigger is second to none. Highly Recommended!

    Outstanding value for the money. Zero trigger creep, very clean second stage break. On par with Geissele SSA.

    This is a really nice feeling trigger. There is a little second stage take-up before the break, but it is extremely smooth. It's easy to learn this trigger. For the price, its a bargain. Recommended!

    Hands down the best 2 stage mil-spec trigger under $200 period . Nice smooth take up & clean break .The quality is amazing as everything Centurion does so if you're reading this you obviously are on the right track .

    I'm pleasantly surprised by this trigger, the AST has a short take-up with a very predictable wall that has the slightest hint of stack before release and a short, quick reset. I've used the SSA, SSA-E and MBT2S triggers and the AST trigger pretty much performs on the same level as the G triggers, but at a much more reasonable price. Going forward, I'll be using Centurion's AST in my Rifles.
