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.

- Smoother and sharper trigger pull than standard mil-spec triggers
- Maintains original sear geometry for high reliability
- Nickel-Boron plated trigger for high surface hardness and wear resistance
- Nickel-Teflon plated hammer and disconnector for smooth, low-friction operation
- Pull weight approximately 6.0 lbs (mil-spec compliant, 5.5–9.5 lbs)
- Trigger and hammer made from 8620 alloy steel; disconnector from 1070 high-carbon steel
- Full-force hammer spring ensures reliable ignition with all ammo types
- Corrosion-resistant mil-spec springs
- 4140 Chrome-Moly steel trigger/hammer pins; oversized for reduced trigger group play
- Standard installation with no need for matched parts or special tools
- Complies with U.S. military requirements for M4 Carbine triggers
- Assembled in the USA

ALG Defense Combat Trigger
by Charles Millo
Nice trigger and easy to install. I also used the KNS non rotation pins instead of the stock pins. The trigger pull is #6 to #6.2 according to my scale.

I've tried the Spike's and WMD NiB trigger group and the ALG is far better than those.
ALG ACT trigger
by Brad Smith
It was easy and fast working with Primary Arms for this item. Trigger works great!
Great for milspec
by Mark
If you're building an AR or just want a crisp, light for milspec trigger look no further. It's not a light trigger, not a match trigger, not a 2 stage trigger. It's just a nice milspec trigger, and the price reflects that. Love that it comes with trigger/hammer pins, and even a guide pin to install the trigger/hammer pins.
Worth every Penny.

If you dont mind a 5.5 lbs pull, I have not found a better trigger for the $.slight take up. good break (that may be snobby but thats the only reason its not 5 star). undetectable (if any) overtravel. quick reset. And smooth the whole way through.
Wow, that is NICE

I used this trigger to replace a stock AR trigger that was smooth but had lots of creep. The result is a lighter trigger pull and no creep. I'm very pleased with the results and would like to purchase this trigger for all of my ARs. Intalation was easy and the directions clear.
