Allow me to throw my two cents worth in.
I am a self processed trigger snob. Unfortunately, I'm also a poor trigger snob which really sucks because a Geissele SSA costs 240 bucks, and a Timney two stage will run you about $200.
Fortunately, there's an less expensive alternative which I'll get to in a minute.
While I've always appreciated a smooth, glassy trigger on my handguns, it never was a big deal for my rifles, but I never was much of a rifleman before.
A few years back, Dennis from Dragon Leatherworks asked me if I'd take a Geissele SSA trigger in exchange for a year's worth of advertising and I said you bet, so he sent the trigger along which I immediately installed in my only AR and promptly fell in love with.
My next build, I kept the milspec trigger that came with the lower parts kit and that rifle became my spare until I sold it, because I just couldn't stand to shoot that trigger after shooting the SSA.
I put together a carbine after I moved here and because it was pretty much a house gun, I put the milspec trigger in that one too. It did the job, but wasn't anything I'd take out to the range after zeroing it.
Then Woody told me about LaRue's Tactical MBT-2S trigger. It was supposedly as good as a Geissele, but was only 90 bucks, so I ordered one for the carbine. That was right before Christmas. Unfortunately for me, the rest of the world heard about them about the same time, so it was six fucking weeks before I got my grubby little hands on it. Waiting six weeks pissed me off so bad that I swore I'd never buy another LaRue again.
Then I put it in my carbine. Oh Dear Lord, it was fucking sweet!!! It's a 2 stage trigger like the SSA with a take-up weight of of 2.5 pounds before you hit the wall, then an oh so crisp and clean 2 pound pull weight before the trigger breaks, 4 1/2 pounds total, compared to a shitty gritty 6-8 pound pull for a milspec trigger. I'm not fucking kidding here, guys - it's that nice.
So much for never buying another LaRue again. I've got them in all my ARs now (except for the one with the Geissele), and I'll never put another one together unless I have a LaRue to put in it.
Tom, one of my readers, shot me an email a few months ago asking my advice on a good, affordable trigger and I told him about LaRue. He now has them in all of his ARs as well. Yes, they're that good.
Be advised that neither the LaRue nor the Geissele triggers are target triggers. They're both advertised as tactical triggers, so while there's others that have a lighter trigger pull, these are designed so that you can take up the slack and hold it while on target without having an accidental discharge and shooting a motherfucker before you mean to.
And now for the good news: Not only have the price for them dropped another 10 bucks to $80, their shipping time is down to about a week or ten days from the time you order it until you have it.
So, if you'd like to have a really nice trigger for your AR but just can't bring yourself to shell out $240 for a Timney or a Geissele, give LaRue a shot - pun intended.
