Triggers

The way we see it, there are three options.

The first is a DIY method requiring you to replace the trigger group springs with lighter ones like JP Enterprises makes. If you can remove and install the trigger assembly, this is an easy job.

There are also drop-in replacement triggers available from several manufacturers. Timney and Chip McCormick both make excellent units that are easy to install and are a huge improvement over the stock trigger.

The best and most reliable method is to have a gunsmith install install the trigger for you (We at Fighting Sheep Dog are stocking dealers for Timney and ALG/Geissele).

Avoid filing or stoning on the engagement surfaces of the hammer and sear. These parts are surface hardened and if too much material is removed, they will be ruined and can cause major malfunctions.

One of the often-overlooked, yet vital component of an AR is the trigger. In fact, second to looking through the front sites, pulling the trigger is often one of the first things you do when picking up an AR in a gun shop, at a show, or admiring the one your friend just got.

But alas, all triggers are NOT created equal.

Let’s look at some of the key components of a trigger, and what to look for the next time you fire a shot.

Key Components of an AR-15 Trigger:

  • Trigger
  • Trigger Pin
  • Trigger Spring
  • Disconnector
  • Disconnector Spring

So what makes one trigger different from another?

Most triggers are made from steel. They can be Duracoated to any color you choose. They pull (on average) between 6-12lbs. MOST standard triggers are guilty of “creep” – the amount of trigger movement before the hammer falls. They also may not have a smooth action…and smooth = fast.

That’s why we sell ALG/Geissele Nickel-Teflon Coated AR-15 Triggers.

So What’s So Great about an ALG/Geissele Nickel Boron Coated AR-15 Trigger?

  1. The ALG Defense ACT trigger pull is smoother and sharper than a stock trigger. This is accomplished by polishing the sear surfaces smooth and HardLubing the trigger components.
  2. Sear geometry has not been changed from the standard profile so the high reliability that the stock trigger is known for is unchanged.
  3. Trigger and hammer are made from true 8620 alloy steel military specification castings, correctly carburized, quenched and tempered for high surface hardness.
  4. Disconnector is 1070 High Carbon steel properly Austempered into the spring range of hardness.
  5. Springs are corrosion resistant and meet military specifications.
  6. A full force hammer spring is used for positive ignition of all type of ammunition.
  7. Trigger and hammer pins are improved over stock mild steel by using 4140 Chrome-Moly steel that has been quenched and tempered. Pins are centerless ground to a fine finish and a diameter 0.001” larger than stock to reduce play in the trigger assembly while retaining a slip fit into the weapon lower receiver. Both pins are Nickel-Teflon coated.
  8. Pull weight is above the U.S. Military minimum pull weight of 5.5lbs but does not reach near the upper limit of 9.5lbs. Generally, the pull weight is about 6.0lbs.
