CMC trigger. Flat or curved?

Friggs · Jul 10, 2014

Hello,
I am thinking about getting a CMC trigger for my 15-22. (Yes I know about the pins being to short. Thanks to you folks.) But my question is what is the difference between a flat trigger and a curved one. Most very gun made comes with a curved trigger. So what is up with the straight ones? Are there advantages? Thanks for the help.

For me the flat triggers are elegant as hell and something you just don't see very often.
As far as advantages, I like how it "breaks" and something that is unique.

I really like the flat triggers, even more when they're Geissele.

I'm more into curves.

Jerry Miculek uses a curved on his Ar's because he says it's easier to get a straight pull. Can't argue with Jerry!

My problem with straight triggers is the difficulty of keeping the trigger finger in a consistant position on the trigger.

On the other hand, a straight trigger makes it easier to put the finger tip at the very end of the trigger, lightening the perceived trigger pull.

I've discovered that my arthritic old fingers don't lend themselves to flat triggers.

With a hinged trigger like the AR, the curve just makes sense.

On a trigger that moves perfectly rearward with no arc, a flat trigger is fine. But I don't like them either way.

The first part of June, I bought a CMC 3.5 lb trigger(curved) for my AR 15(not a S&W) from Brownells. It came with anti walk pins that have small allen head screws that screw into the end of the pins. When installed on my AR, the pins protrude just slightly and have some play in them if pushed with a finger. Looking at them , they look to have maybe .150" protruding. I'm thinking maybe these pins would work on the 1522.

I'd bet it's more of a marketing fashion idea than anything based on physics. If everyone else makes curved triggers then the straight ones become eye-catching and different. Just think of how many products in history have been wildly successful ONLY because they were cosmetically different than an identical product.

As for the CMC trigger, it's a great product and I doubt you'd ever notice a difference between the straight and curved trigger whichever you choose.

I think straight triggers look somewhere between ugly and goofy.

But I much prefer the feel of the straight- no contest. To pull a standard AR15 curved trigger, my finger is overcurled- which makes it harder to smoothly pull it straight back. The flat face of the straight trigger fixes this very nicely.

I came to this discovery when I was trying to decide between a Geissele SSA-E and an SD-E for an AR build. I was going to go with the SSA-E, because and AR ought to have a curved trigger. But then I pulled out my 15-22 (which has an RRA NM in it) and my 522 (stock flat trigger) and pulled them both just comparing trigger shape. I asked my wife to do the same. We both quickly settled on the straight SD-E, looks be damned. It feels fantastic every time I pull it (and I can't even see it when I'm using it

).

Search SSA-E vs SD-E, and you will see lots of opinions about flat vs curved.

Ewww, I just searched on the CMC flat trigger. That is very likely the worst looking AR trigger I've ever seen- makes the SD-E look quite lovely by comparison.
