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.

- 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

ACT
by Ryan S.
Fast shipping as always from Primary Arms. I was debating between spikes tactical trigger and this one. After a bunch of research I finally decided on the ACT trigger. I had it installed in less then 10 minutes. I even put a reduced spring kit from Wolff on it. I didnt have to but, I heard it makes an amazing combo. On the first pull I immediately noticed a huge difference. I had a dpms trigger kit. By round 60 it started to feel even smoother. If I had to guess the poundage on the trigger I would say it breaks at 4.5 to 5 lbs. The pull is like a hot knife through butter and breaks so crisp. I can look through my scope and have the trigger break and the scope actually stay on target. Groups are sub 1" at 100 yards. I could not be happier. For me this trigger is the perfect combat trigger. If your looking for an upgrade for your ar platform at a price that wont break the bank and still have amazing performance. This ACT trigger is for you!!!

Easy install and 100 times better than factory trigger.
Love it so far
by TS
don't have a ton of rounds through it yet but I like how much smoother this is than a standard mil-spec trigger. BCM makes great products but I've found their standard triggers to be horrible. For the money this is a great buy and worthy upgrade methinks.
Act trigger
by William Cotter
Bought this after installing a factory trigger that came with the LPK. That one was terrible to say the least. The ACT trigger was the best thing I ever bought for this build. What a difference. If your looking for a nice single stage trigger pull , look no further than alg act trigger !
