Same here...super impressed with the ALG triggers and even more so by their price.
I talked a buddy of mine into using the ACT in his latest build. I've pulled that trigger a number of times and I've fired a couple mags through the rifle. I'm so impressed I decided to build a hunting and short/mid-range varmint lower around it...just something I can use around the property to dispatch critters. I have Geissele's SD-E in one rifle, and I've owned another with their SSA trigger, so I'm not new to Geissele's work. For $45 or $65, I'll probably never run a mil-spec trigger in anything again, even temporarily.
I think these two ALG single stage mil-spec (type) triggers will most likely replace the SSA in my future builds...the SSA is nice, but I think I could learn to use the ACT just as effectively. The SD-E, on the other hand, isn't going anywhere. It's a great precision trigger, but heavy/predictable enough that I'm really not afraid to use it when I'm hunting.
