So I was buying some other items and thought I'd give the ALG QMS trigger a try. Relatively inexpensive and makes no claims to be a target or match trigger, just an improvement over the typically long and gritty pull of most stock triggers.

I'm probably telling you something you already know, but the improvement is vast. The pull is not actually lighter, it is advertised as not being lower than 5 1/2 pounds. However, there is very little take up and no noticeable over-travel. I'd compare it to a mid to low end bolt rifle trigger. If you can manage the stock trigger on a Ruger 10/22, this will feel like a dream.

If i were building another target or varmint rifle, I'd spend the money on a Geissele. For a general use rifle or carbine, I think I've found my new default trigger. Now I've got to order a few more and install them on the rest of my rifles.
 
My brothers BCM came with an ALG trigger. Very smooth, crisp trigger. Just right for a general purpose carbine, as you said.
 
How do they compare with these?

Got one coming for 30 bucks shipped. Good reviews...hope they are as good.

It should be comparable, maybe the PSA being a little better depending on your luck. (for the ALG QMS. The ALG ACT wins every time.)

ALG has two triggers, the QMS is a tuned Mil-spec trigger, the ACT is a tuned Mil-spec trigger that has been treated with NiB to have less friction.

The PSA is coated with NIB, but I do not think they put nearly as much effort into tuning it as the ALG. Mine have been almost as good as the ALG ACTs (FAR better than stock) but others have gotten trigger sets with bad geometry. So if a PSA has good tolerance stacking, it is excellent. If it has bad stacking, pretty much every ACT sold will be better.

I have 3 ACTs and 3 PSA coated trigger sets installed. I cant tell which is which unless I handle the guns side by side.
 
You'd be surprised what a lot of rounds and some grease will do for a gritty GI trigger...

The enhanced triggers (ALG ACT, BCM PNT, SIONICS Enhanced, etc.) are the shortcut to the same end result.... a decent trigger.
 
I've shot rifles with enormous round counts. Some owned by me and others owned by our rich Uncle Sam. Enormous being tens of thousands of rounds and multiple barrels and bolts. Wear does improve things, but it will not reduce take up and over travel. Those two items are far more important than pull weight or gritty feel. If every rifle came with a trigger like the ALG, I suspect aftermarket sales would be halved, at least.

I agree completely with the grease, though. Most people squirt some CLP or oil in the FCG and call it good. That works, but grease is where it's at when it comes to trigger mechanism.
 
And for those who know what they are doing: whether it is a Spikes enhanced or ALG or PSA enhanced plated trigger a few minutes with a hard Arkansaw or 1500 grit diamond small tapered slip stone takes down the little micro hooks and imperfections that still come on these triggers' sear contact areas without breaking thru the plating and after cleaning a drop of Slip 2000 EWG to the pins and bearing surfaces gives 100% improvement over out of the box !
 
All of my ARs have the ALG triggers, one has the ACT and the rest (4) have the QMS.

IME/IMO they are worth the extra money. The ACT is 5.5 pounds and the QMSs range between 6 pounds and 6.5 pounds. All of them have very little to no creep.

The stock triggers that the ALG triggers replaced ranged from 7 pounds to 9.5 pounds and all of them were gritty, creepy, and inconsistent regardless of how much grease was used or how much dry firing/live firing was done.

Just my .02,

I haven't had a chance to shoot it yet, just dry fire. I picked up a set of JP Enterprises 3.5T springs, the "enhanced reliability" with red hammer spring. Lots of stuff on the net about reduced weight package with yellow hammer spring. Not so much with the red. I'll give an update in a few weeks when I can burn a few hundred rounds of M193 and check reliable function with the combination of ALG trigger and JP red hammer spring.

I put the springs in after my original post. The pull is noticeably lighter and take up and over travel are unchanged. However, the break loses a bit of the crispness. More of a very short "roll off" than a crisp break. I'll leave the springs in long enough to check reliability, but am already considering putting the ALG supplied springs back in the rifle, before I've even fired a shot. We'll see what the range time tells me.

I prefer a slightly heavier but crisp break than slightly mushy. I'm also not willing to give up reliability. I'll post an update later this month when I can evaluate the combination with actual shooting and determine if reports of light strikes with the yellow hammer (3.5 kit) spring are also an issue with the red (3.5T kit).
 
I shot the rifle this past weekend with the ALG trigger and JP springs, specifically with hard primer NATO M193 ammunition. No light strikes after 200 rounds. But I'll probably put the ALG supplied springs back in just because I prefer the crisper let off.
