ALG Defense QMS & ACT Triggers - Tuned by Geissele

[John Hwang]

ALG Defense Quality Mil-Spec (QMS) - $45

The ALG Defense Quality Mil-Spec (QMS) Trigger is designed for those shooters where tradition, value and regulatory concerns are of primary importance. The pull of the QMS is very similar to a standard mil-spec trigger, however the majority of the associated grittiness of the stock trigger pull has been removed while the well known reliability of a stock trigger remains. The pull weight is not lower than the M4/M16 minimum weight specification of 5.5lbs.

**Tuned by Geissele Automatics**

Performance Advantages for the Shooter:

• The ALG Defense QMS trigger pull is smoother and sharper than a stock trigger. This is accomplished by honing the sear surfaces smooth while not removing metal below the valleys of the stock surface finish.
• Sear geometry has not been changed from the standard profile so the high reliability that the stock trigger is known for is unchanged.
• Trigger and hammer are made from true 8620 alloy steel military specification castings, correctly carburized, quenched and tempered for high surface hardness.
• Disconnector is 1070 High Carbon steel properly Austempered into the spring range of hardness.
• Springs are corrosion resistant and meet military specifications.
• A full force hammer spring is used for positive ignition of all type of ammunition.
• 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.
• 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 6.5lbs.

Advantages for the Armorer:

• The ALG Defense QMS trigger is an enhanced standard trigger so maintenance and installation procedures are unchanged.
• There is spare parts commonality between the QMS and stock triggers
• Trigger assembly parts may be interchanged between triggers, there are no matched sets.
• Since it is a trigger meeting the U.S. Military trigger specifications for the M4 Carbine, the ALG Defense QMS can be substituted for lower performing stock triggers while still staying in compliance with Unit or Departmental requirements.

ALG Defense Combat Trigger - ACT - $65

The ALG Defense ALG Combat Trigger (ACT) is designed for those shooters where tradition, value and regulatory concerns are of primary importance. The pull of the ACT is very similar to a standard mil-spec trigger, however it is sharper and the grittiness of the stock trigger pull has been removed while the traditional reliability of a stock trigger remains. The pull weight is not lower than the M4/M16 minimum weight specification of 5.5lbs.

**Tuned by Geissele Automatics**

Performance Advantages for the Shooter:

• 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.
• Sear geometry has not been changed from the standard profile so the high reliability that the stock trigger is known for is unchanged.
• Trigger and hammer are made from true 8620 alloy steel military specification castings, correctly carburized, quenched and tempered for high surface hardness.
• Disconnector is 1070 High Carbon steel properly Austempered into the spring range of hardness.
• Springs are corrosion resistant and meet military specifications.
• A full force hammer spring is used for positive ignition of all type of ammunition.
• 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.
• 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.

Advantages for the Armorer:

• The ALG Defense ACT trigger is an enhanced standard trigger so maintenance and installation procedures are unchanged.
• Trigger assembly parts may be interchanged between triggers, there are no matched sets.
• As a trigger meeting the essential U.S. Military trigger specifications for the M4 Carbine, the ALG Defense ACT can be substituted for lower performing stock triggers while still staying in compliance with Unit or Departmental requirements.

Note about HardLubing:
HardLubing is ALG’s term for electroless Nickel plating with an integral modifier to the base nickel plate. Either Boron or Teflon is used to enhance surface hardness, wear resistance and corrosion resistance and also create favorable tribological properties of the trigger components. Testing has shown that differential coating of the trigger parts contributes to the sharpness of the ACT’s single stage pull. The trigger component is plated with Nickel-Boron which has a high surface hardness combined with excellent wear resistance. The color is a pleasing matte light grey that may be painted on non-functional surfaces if the shooter so desires (such as the trigger bow that is visible outside the lower receiver). The hammer, disconnector and trigger/hammer pins are plated with Nickel-Teflon which combines a low coefficient of friction with good wear resistance. The Teflon impregnation colors the metal a mottled, greyish/green. Parts coated with Nickel-Teflon cannot be painted. Both coatings are highly corrosion resistant eliminating the oil seal of traditional phosphated firearm components.

All I have to say about Amy Geissele's new ACT trigger is...awesome. I compared it to two other mil-spec triggers. All three are identical being that they all came from the same supplier. But Bill Geissele really worked his magic on these and comparing them, it was night and day.

Just so I can cut to the testing, if you want more tech spec info, you can download the product specs here ALG Defense


Packaging was well sorted. Trigger components came completely assembled. Trigger and hammer were separated by a moisture absorbing sheet that seems to keep things lubricated too. It also helps to keep the parts and contact areas from getting dinged up by each other through fulfillment and shipping.




At first comparison, the ACT parts feel super slick vs. the standard mil-spec kits. Bill Nickel-Boron plated the trigger and Nickel-Teflon plated the hammer. It has tempered Chrome-Moly pins and quality springs. ALG includes a slave pin and grease too. Everything is corrosive free. Pull weight is light for a combat trigger. My friend has the digi trigger weight scale so I was not able to measure it yet, but it does feel like a lighter 5-6 lb pull. Initial pull is so incredibly smooth...and bam. Clean break. There is nothing "squooshy" about it. It's just a great single stage trigger.




Luckily, my client friends' own a medical district campus that is also home to a police training/firing range. With the help of a SWAT friend and another competitive marksman, we compared my best mil-spec trig group up against the ACT in my 14.5" 416 upper on a semi-auto clone lower. Aimpoint T-1. No muzzle break, just a Surefire FH556. Same Federal ammo used for each shooter. The goal was simply to compare the triggers with rapid fire 5-shot groups.




A few other cops wanted at it, mostly because the test host was a 416. But everyone was thoroughly impressed with the ACT triggers smoothness and clean break. They have restrictions for upgrading their duty rifles, but everything about the ACT is mil-spec, so they will be looking to get approval.

It's really is a fun trigger to shoot fast. And @ $65, I can upgrade a few rifles for the price of a higher-end comp trigger. Shoot, I think I already sold some at the PD range.

SWEET!

It's very sweet!

Looks like a great trigger. I want one for my OA.
Any possibilities to get them in europe?

Took it out again and tested a Surefire and BattleComp brake. Both brakes work great and either one with the ACT feels competitive enough for rifle matches coming up. Can't wait!

Hi jhjfdf
Contact Bill Geissele. He might be able to point you in the right direction. I know a friend who shoots internationally in the UK said he knows a guy who has a G-trigger, so they're getting over there somehow.

[jhjfdf]

You can get Geissele triggers in europe...but for example the Super 3 Gun (SD-3) costs 435 Euro here....and thats too much

Usually the shipping costs are 50-100 dollars...so i would prefer a store where i can buy some other stuff( magpul,rails...) so it pays off to order.

[jhjfdf]

Received a email from Amy Geissele...they dont ship outside US

The ACT:

We put an ACT into a gun last night. Not that thrilling yet. I hope it improves with a little use. But that said, it's still a solid single stage trigger. The creep is still there, it's just not gritty. We'll live fire it soon. If you handed my the rifle to shoot and I didn't see the color of the trigger, I wouldn't know that it wasn't a GI trigger at all.
