Looking for some experience/advice here.
Have a new S&P AR. Nice piece, but not totally happy with the trigger. It's got kind of a long pull. Not slack or takeup, but just a long travel, and a little rough when I first got it. Pulled it out, polished the sear and stuff. Smoother, but obviously, doesn't change the travel (or creep?)
Thinking about new trigger group or a drop-in, but hate to spend money on something that I can't try out first. Anybody got a favorite? Looking for a nice short, crisp release, of course.
Thanks.

For two stage. ALG makes a decent trigger for under $50 QMS or $70 ACT for better one. Geissele Hi-Speed Match Rifle Trigger is top of line, runs about $300. Timmy and couple others fall in between. Rock river NM runs $120 and is pretty good.
If you like single stage, JP triggers are pretty nice and run just under $200, breaks like thin glass rod.

Thanks, Robert. Couple other questions, but first, I typo'd in my first post. What I meant to say is that it's an S&W M&P, not an "S&P." In particular, this one is an M&P10 (the 7.62). Is the AR15 trigger the same? They look the same, but don't know if they have bigger springs for the 308 or if there are any other differences, or should I be able to put one of these fancy AR15 triggers in it?

When I first got my M&P-10 I went through the same thing. Polished
everything, lighter springs - all the things that make a AR-15 trigger
better. I was able to improve it quite a bit except it wouldn't light
off mil spec ammo. The primers are too hard for the light springs.
Most of the aftermarket trigger manufacturers have a different models
for AR-10's. I have lots of experience with AR-15 triggers. Like
RobMT I like Timney and Geissele but have not tried them in the 10.
The single best thing you can do for the $$ is a grip screw trigger
adjuster. It takes out most of the creep and lightens the pull. Easy to
install but takes a little patience to adjust properly. You can actually
adjust out all of the creep and get the pull to < 3# but the trigger won't
reset. So you have to keep backing it off until it functions reliably.
I've used both NicTaylor00 and Joe Bob models and they both work.
Remember to loc-title and they'll work fine. I have at least six of them.
My M&P-10 is at a crisp 5.5#.

Replacing the springs, will help with pull weight, for AR10 models, you want at least red hammer spring, grey is slightly heavier http://www.jprifles.com/buy.php?item=JPS3.5T - JP
JP trigger has adjustments for sear engagement and over travel, be aware that both JP and adjustment screw, to reduce sear engagement, require filing safety flat and disconnector, for full adjustment. They also can cause doubling, if you're not careful and reduce sear engagement too far.

Thanks Robert. Did check out a video on installing the screw and can see how those factors could be issues. Might look at a decent 2-stage drop-in. Trouble is, if I like it, I'll want to put one in all ARs. Ka-ching. $$$

Problems occur with the grip screw adjuster when it is set too light.
When it's cranked down all the way it will be just like a $230 Geissele
but will only function as a single shot. Once you feel that it's hard to go
back. You just have to justify the $200 +/- for a real trigger vs $10-15 for
the screw.

If we relied on logic, justifications, rationality, good sense, return on investment, or any of those other silly principles, we probably wouldn't have most of the cars, trucks, guns, tools, etc.
I watched the video on putting in one of the grip screw thingies and he was replacing the trigger spring as well -- so of course out comes the whole group. If you're not going to replace any springs, it looks like you wouldn't have to take anything apart except to replace the grip screw. Is that right?

Ordered a couple of those grip screw trigger stop adjuster thingies, so will try that approach before spending real money. Report to follow at some point.

After the trial and error part of the initial adjustment I've learned to
screw the small set screw in all the way and count the revolutions. Just
like the jets on an old carburetor. Then you take it all the way out and
apply the loc-tite. Screw it all the way in again and back it out the
amount you counted.
I ended up with a lighter power trigger spring and an extra power Wolff
hammer spring. As I mentioned before if you only shoot factory or hand
loads you'll be fine with factory or lighter power springs. I have a couple
tins of Australian mil surp ammo with hard primers that I sometimes
shoot. Without the heavy spring it would only light 3 out of 5.

Good advice. Thx, Dog. Will try this and experiment a bit, then decide if I want to do any spring swapping.
