The ALG Defense Advanced Combat Trigger (ACT) is a premium upgrade for AR-15 rifles, designed for shooters seeking the trusted reliability of a mil-spec trigger with enhanced smoothness, sharpness, and corrosion resistance. Featuring a pull weight above 5.5 lbs to meet M4/M16 military specs, the ACT improves upon standard triggers with HardLubing—ALG's advanced electroless nickel plating process using Boron or Teflon to deliver superior wear resistance, low friction, and excellent corrosion protection. Ideal for law enforcement, duty use, or value-conscious builders, the ACT maintains stock geometry for consistent function while offering a refined single-stage trigger experience.

Nice trigger
by Shane Portier
Wanted a better option to my stock trigger and this fit the bill nicely. A lot cleaner feeling and easy to install. Primary arms is great with shipping and is always the first place I look for items.
Very nice for the price
by Joey Graff
Very smooth pull and break. Primary arms was fast just don't use FedEx for shipping though, they tried delivering 3 time at 1pm! I finally had to drive 45 min to closest pickup location.
Great trigger for the money

Really nice trigger.
by Jesse Reich
Very happy and can't beat the price.
Outstanding Trigger
by J. Tapley
Title says it all. This trigger has an extremely smooth pull. It's short just like the mil-spec. It's not a competition trigger but it's probably the best trigger you'll want for duty and self defense purposes. Let's just say the trigger will break better than most can shoot.
Great price and solid trigger
by Mark Noe
This trigger is solid. Purchase with confidence. As always Primary arms shipped quickly. Solid company!
Worth twice the price
by Josh W
This trigger is much smoother than a standard one. There is no creep, no gritty feeling and just a hint of over travel. The reset will take a little getting use to, it's very positive but just feels different. Overall this is a quality product and I highly recommend them for a defense type rifle.
awesome upgrade
by PATRICK KRAMER
This trigger is a bargain for the dramatic improvement over a basic mil spec trigger. Its not a match trigger, but I didn't want/expect that anyway.
Great value
by Josh
This trigger has a great fit and finish and the pull is smooth. Not a 2 stage match trigger like I have in a long range ar15 but exactly what I was searching out for my "battle" rifle set up.
