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.
Features:
- 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

Awesome trigger for the money
Best for the money.

I replaced my Ruger SR556C stock trigger with a ALG. OMG why can't Ruger use a trigger like ALG? Even bigger bonus is the ALG hammer isn't eating up my firing pin anymore like the Ruger hammer was.
these triggers are great for the money

This is the best trigger I have out of all my AR rifles. Smooth and perfect release. Could not ask for a better trigger. I will buy more as needed. Lots of rounds down range!

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.
excellent value

If you want something better than a parts kit trigger start here. I have 2 of these with several thousand rounds through them and they are as consistent today as the day I bought them.
