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

good prices fast service
by Bill G.
Bought an ALG trigger on sale. Great price and fast reasonable shipping. Had to pay tax cuz i'm in Texas, but still better than buying for any other vendor.
Good upgrade
by Kevin Matlock
Better break and without the grit of a standard mil spec trigger.
ALG ACT trigger
by Trevor Bready
Awesome trigger for the money. Clean, crisp break. Installed it with 4 lb JP springs. I can't see spending $200+ on other units when this one works so well.
Great milspec replacement trigger
by Loren Bradford
Awesome trigger at a great price. For anyone wanting to keep a semi-milspec trigger feel you won't find anything better.

Geissele trigger on a budget!
by Daniel S
ALG products are a total favorite. All of the great geissele features and perfection at prices that don't make you cry. This trigger is a wonderful mid level trigger for those who want far better than stock performance without the big price tag.
Great trigger for the money
by Garry
A much improved trigger over the one that came with my LPK. The pull weight is comparable to the standard trigger, but much smoother with a cleaner break. I now have one in two rifles, and for hunting and shooting steel, this Tigger is a great investment for the money. Five stars for the value and primary Arms service
ALG (the non-Geissele Geissele)
by S. Karg
ALG triggers are worked at Geissele so you know it's a quality product. This is a very nice, predictable trigger with plenty of adrenaline and stress induced error left in the pull weight. Bill Geissele's wife offers a quality product at a competitive price. Oh, and Primary Arms rocks!
