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

Great company and service.
Almost perfect
by ScottsBad
Good trigger, better than stock and comes from a company of unquestionable pedigree.Would like to see a slightly lighter spring set for a lighter pull. Although the springs they provide seem to be of very good quality.Reliability is the number one job of a trigger and this one will probably prove to be highly reliable over the long term.Appears to be very good quality overall with a nice finish. Wish these came with every parts kit.

For 65$. This trigger cannot be topped. Exceptionally smooth trigger. It even comes with a 4.5# spring as well as mil-spec spring which is awesome.
