Hello all,

i am a new smith and wesson mp15 sport owner although not entirely new to this platform.

i used a colt m4 a3 when i was in the army for a number of years and two combat deployments so the ar platform is familiar however i have never ventured into the realm of upgrading and what not.

i bought the m&p 15 sport after careful rebiew of many aspects and decided to fit my purpose it would be fine after all through all my time in the army not once did i use the forward assist and even with the ejection port cover they still get dirty.

now since i have owned the rifle i have put around 100 rounds through the rifle i have an aimpoint red dot for a sight. at 50 yards i am consistantly putting independance 55 grain fmj bullets into around a 1.5 inch group with the occasional group under one inch. i feel that a better trigger may help me in tightening up the groups or an optic with magnification so i have decided to do both.

i have already decided on the optic so that leads me to the question of my opening post here on this forum.

i am looking for m&p 15 owners who have upgraded their trigger and would like to share brand specs and any helpful information and suggestions you might have.

thanks in advance for replies and advice,
Josh

Congrats on your new 15-Sport & welcome aboard!

The top tier triggers: Timney and Geissele. I never hear a bad thing about any of the triggers in their line. My only issue is the price. What's your budget? If you're looking for a good combat trigger, ALG defense makes a very crisp combat trigger that won't break the bank.

I have two AR-15's. My home built AR-15 is equipped with a Rock River Arms National Match 2-Stage trigger. My 15-Sport is equipped with a Rock River Arms 2-Stage Varmint trigger. Take up the slack, hit the wall, pull and the trigger breaks. The Varmint trigger is lighter, but difference between the National Match 2-Stage and the Varmint is barely perceptable. Both have KNS Precision Gen2 anti rotation pin kits installed.

I paid around $99 each for the RRA triggers. The KNS anti rotation pin kits were each $30.

The RRA triggers and KNS anti rotation pins were among the last things I installed on both my rifles. I wish I had done it sooner.

thanks for the info i have thought of timney because i have a timney in a Remington 700 just did not know if they made ar triggers.

budget is of no concern i could have easily chose another ar but like the weight and the slick look of the sport
 
You should also look at the Wilson Combat TTU. Mine is a single stage 4 lb..however they also make it in 2 stage if you happen to like that mode.
They are a bit more costly, but IMO well worth it.
 
after looking at the timney tonight i may have to buy one it is not the two stage and it is 279 dollars.

how much is the wilson?
 
Geissele ssae. 2 stage. I paid$179. Primary arms has them for $230. I've seen them for$199 there on sale.

Geiselle ssae 2-stage (as AR-Getsome pointed out) has been my favorite so far. Although after reading JaPes post, I am going to have to try out a RRA 2-stage on my next build (love to price point!), especially for a CC purpose build.
 
Or if you are handy. I just pull the trigger and lightly pollish the parts. You'd be surprised and what you end up with and it only cost time. I've yet to swap out any trigger in any of my MSR's.

I've polished a few AR-15 combat triggers. I pair them with JP Enterprises Yellow reduced power springs, and it isn't bad. I know oneyeopn has it down to a science.

No matter how good I got at polishing a trigger, I couldn't get the same results as an aftermarket 2-Stage trigger. I've shot an ALG defense combat trigger, and that one was better than a standard polish.

...anything is better than a brand new stock combat trigger.
 
I think you'll be happy with the Timney. I have the Timney 3lb and the only, and I do mean ONLY, thing I wish was different was that I had the skeletonized one lol. For super accuracy I've always heard two-stage was the way to go, but I've never had trouble with a single. I'm not near as proficient a shooter as a lot of the guys here, but with my Timney I can definitely still feel the breaking point. I had really good results with the "15 minute trigger job" and polishing, but still prefer the Timney.

In my younger years (40+ ago),I was taught by one of "the good ol' boys" and never looked back. It is time consuming doing it right. It's one of the first "fine tuning" things I do to a new weapon. Saved a lot of money over the years on triggers. :)

I've traded notes with Grover about it in the past. Seems he's picked up the knack for it too. :)

Yup. You and Grover are the ones that gave me the impetus to learn to polish a stock AR-15 combat trigger. I'll admit to ruining the first one I tried because I was too eager in my stoning. I had a stainless trigger polished to perfection. I still have it in my parts bin.

I use mild/light grit paste and (the dreaded) Dremel with a buffing wheel.

I'll admit stoning has taken me too close to the point of no return in the past. That's why I went to the buffing paste and Dremel. Slow and easy.
 
I have a Geissele SSA in my 5.56 and SSA-E in my .308. Great triggers and no need to buy KNS pins. In fact Bill Geissele himself doesnt recommend them. If you like two stage triggers these are awesome! If your looking to spend less the ALG defense are a good option. My PWS rifles came from the factory with these.

I also use the buffing (I think it's cotton with some sort of reinforcement threads) and different compounds. I've found aluminum or chrome rim polish works great.

Another trigger I've spent a little, and I do mean little, time with was the CMC single stage. You can get them in single and two-stage, and curved or flat for you 1911 guys. I still don't get the point of the flat trigger tho. They're pretty nice drop-ins and the guy told me they come with anti-rotation pins so that's a plus.

You can do the 15 minute trigger job (15 Minute Practical Trigger Job for the AR-15) or the $.50 trigger job (Junk Yard Genius.com AR-15/M-16 Pages, page 1.), or a combination of both, and you will improve the stock AR trigger pull. But these modifications will never match a custom aftermarket trigger, like Timney, Geissele, etc. The stock AR trigger geometry pulls the hammer back slightly, at the end of the trigger pull. The custom trigger's geometry is different, and only releases the hammer, and does not pull it further back, which allows for a lighter pull and crisper break, along with other improvements to the pull.

One thing I have found that helps the stock AR pull, is a dab of anti-seize grease on the contact surfaces of the sear face and the hammer. A very small amount is all that is needed. It works like the expensive sear lubes sold at the gun shops and parts distributors. I've tried all kinds of oils and greases, and the dragging/gritty pull remains or returns. Using the anti-seize eliminates this issue. It is very inexpensive at the local auto supply. I use Permatex brand #133A in a 1 oz. tube. This tube will last forever, and is under $5.

I have one of Grovers Triggers in my Carbon AR15... really like it... just a bit over 4lb pull and nice and smooth..

I also have a CMC in my 15-22 and it ROCKS... Hits like a Mule and just over a 3lb pull... Perfect for my Slidefire..
When i got the CMC I put the Timney in my S&W Sport... made a HUGE impact on my Accuracy for sure... Great Trigger for sure

I think between the Timney and CMC I'd go CMC... I tried it in the Sport for a Range trip, and I tell ya, that heavy hammer hit is Awesome...
