Hi all, I just installed my new ALG ACT trigger. I used the spring that was installed (the lighter 4-1/2# one), there is a second choice in the package, a spring with about 6# pull.

My question is, before I go to the range, which spring should I use? I know if I have light strikes I can change to the stronger hammer spring (which will eliminate them), but I don't want to waste a trip to the range with the wrong spring.

What is your recommendation for my first trip to the range with the new trigger?

Hopefully the lighter one works well as it feels really good!

Thanks in advance,

Rick

4.5 should ignite any primer IMHO. I would go with that. What ammo are you shooting? Some brands are known to have harder primers.

Wolf Gold 55gr, Speer Gold Dot 64gr, American Eagle 223 55gr and American Eagle 556 62 gr. are the range ammos I use. All brass cased.

My understanding is all but the 556 are factory new. The 556 American Eagle might be factory re-loads, but I don't know for sure. I have found it is sometimes real hard to know what you are buying when it comes to ammo, as a lot of descriptions are kinda vague.

American Eagle is Federal and is not reloaded it is factory new, some of it is loaded at Lake City ammo plant and is not as "polished" as commercial ammo might be. Also some of the Lake City might be rejects that do not meet military specs but should be safe and functional.

The weighted springs only affect trigger pull weight and not hammer strike force, this is assuming the only difference between the two is which spring is installed on the trigger itself.

My personal preference is the 4.5# trigger since it is a good compromise between range use and field use. Anything lighter can be a problem is something gets stuck in the trigger guard while pushing through brush and what not and it's light enough for better accuracy at the range.

Not to say a 6# wouldn't work but the heavier the trigger pull, the harder it is to maintain shooting fundamentals and getting the tightest groups possible.

The ALG ACT trigger has only one trigger spring. There are TWO options for the hammer springs, and the lighter one reduces the [I]trigger [I] pull from 6 pounds to approximately 4-1/2 pounds. This info is per the instructions sheet that accompanies the trigger directly from ALG.

On a side note, I only have one other modified trigger on any of my long guns, on a tactical Ruger 10-22 I have a 2-1/2# pull Brimstone trigger, that breaks like a glass rod. This ALG trigger feels just as smooth and breaks more like a peppermint stick at a pull that is not quite as light as the 22LR. (I don't have a pull gauge). Overall, I am quite impressed with this trigger. It is everything I need for a rifle to be used for field plinking and home defense. For anything other than match shooting from a bench, I'd highly recommend the ACT trigger.

Interesting that they change the trigger weight via the hammer spring instead of the trigger spring. Since ALG is associated with a company of high regard like Geissele (owned by Gessele's wife), there should not be a problem with light strikes then.

When I go to upgrade my 10/22 trigger, I'm going to go with a KIDD trigger since I can get one in 4.5#. I don't plan on competing with it, so don't feel the need for a lighter trigger but if I ever get into competition, I may think differently since the smallest measurement difference can be the difference between winning a match and not.

For what it's worth I use the lighter 4.5# purple spring in a couple of my rifles and haven't had any problems with FTF.

If you ware worried just take both springs and a punch to the range it's a 2min job to switch them.

What are the odds?
I just installed the same trigger in my AR yesterday too.
I went with the 4.5lb spring.

How do you like it? I'm more than thrilled with mine. Now if only I don't have any light strikes, I'll be in heaven.

Thanks for all the input. I really value your information on this board. Speaking of boards, this one seems to be the best one for me, as the other one, "ar15.com" seems to be just too technical for my tastes.

I've tried it with snap caps so far. It is a definate improvement.

You guys might want to try out a trigger adjuster too, it's basically a set screw that goes through the grip screw that you can adjust to take out all of the creep and reset travel from the trigger. Paired with an ACT it's probably as good of a Mil-Spec style single stage trigger as you can get. I have one of these with my ACTs and it really gives an unbeatable trigger for the money.

WOW! How does this thing work? Sounds like it might be worth looking at since I've never heard of it before.
