My next project to improve the new M&P 15T rifle that I just purchased is replacing the trigger. The stock trigger isn't awful, but I'm looking for something that has less pull, better feel, and crisper break so I can shoot out to 200 yards with precision. I have a Savage 10 Stealth rifle with the Accutrigger and I love it. Unfortunately, I don't think I can get that trigger from Savage and drop it in on my M&P 15T. Any ideas on a trigger that would be similar to the Accutrigger from Savage? Pros and cons of single stage vs. two stage? Any tips or tricks in removing the stock trigger and installing a new one? For right now, I'm leaning towards the Geissele SSA-E...I just have to convince the wife to let me drop another $240 just for the trigger.

Just out of curiosity, what did you pay for this rifle? How did it compare in price with the SAINT, the Colt OEM 1&2?
I just recently bought an AR STONER trigger from MIDWAY, but, I imagine you are looking for something a lot better. Stay tuned, there are some very knowledgeable members here that will give you great advice.

I paid a little more than $960 for the rifle at Tombstone Tactical here in Phoenix, AZ. I believe the Colts were about the same price, maybe slightly more. The Saint was about a $100 cheaper. I look at an inexpensive AR STONER trigger but I wanted something drastically different than the stock trigger. The upside to the AR STONER trigger was that I could purchase it and my wife would never know. I can't slip the Geissele purchase by her as easily!

You might want to look at the LaRue MBT2s. It's a very good 2 stage, and if you don't have to have it right away the price is 124.95 + shipping.

They aren't cheap but Geissele and Timney both make superb triggers for the AR15.

The Timney is a single unit drop in trigger and as a result is very easy to install. As for the quality of the Timney Single Stage I have the 3 lbs. version (actually measures at 3.5 lbs.) in 3 of my AR15's and they are very close to the single action trigger on a cocked S&W revolver. Meaning no pre-travel or creep that you can feel at all, apply enough pressure and the rifle will fire. Now some will claim you shouldn't install a light single stage trigger in a semi automatic rifle for fear of a "bump fire" event but IMO the AR15 just doesn't kick hard enough for that to be a concern. Note, if you really do think a 2 stage trigger is essential Timney just released a 2 stage drop in trigger for the AR15 and based on my experience once to take up the pre-travel it will behave quite like their single stage trigger.

The Geissele is also very highly thought of and does come in a lot more versions for the AR15, so many you really need to consult with a Geissele expert to determine what is best for your needs. BTW, by versions I mean the pre-travel is offered in different lengths and weights, they offer single stage triggers in a variety of weights, and IIRC they also offer triggers with a shorter than normal reset for competition shooting events. The Geissele is also NOT a single drop in unit, it's basically a bag of parts containing the Trigger, Hammer, Sear, and springs. As a result installing the Geissele is a lot more "fiddly" than dropping in a Timney trigger. Which is why my rifles all have Timney Triggers, because I just am not as patient as I should be and fiddling around trying to get springs compressed and parts correctly aligned tends to have me throwing things.

I shoot offhand out to 200yds. Mostly practice with steel. No precision paper shooting. Generally warm climate (no gloved shooting).

My preference is single stage. I chose the Wilson Combat TTU 4lb. Well designed self contained... no adjustment screws to fiddle with and 1911 style half-cock notch for safety. Clean crisp break and short fast reset. Here's a review. I haven't gone through 10,000 rounds just yet... but so far this trigger has lived up to everything I've read.Wilson Combat Tactical Trigger Unit (10,000 trips of the trigger)

I've got a Timney 686-S single stage 4lb in one my .22 AR platforms. It's ok but feels mushy compared to the WC.

---- Everyone has their own budgets and priorities... but IMO the trigger is among the last places to try to save a buck at the expense of not getting the trigger ya really want, whatever that might be.

I have used a couple of ALG ACT triggers and was very satisfied with the results. They have a hair over 5 pound pull weight with my gauge but are very smooth and clean on the break so they feel much lighter and the price is very reasonable so you can try one and not be out much at all.

I use CMC drop in triggers in all my better quality AR builds. I purchase them when I find them on sale. I have found them as low as $125 which is a fantastic bargain. In my opinion a performance trigger should be the first upgrade made to any AR with a Mil Spec trigger. Midway has the CMC's on sale right now for an OK price. I like that the CMC triggers come standard with the anti-walk pins included.

The Rise Armament RA-140 is also a great 3.5lb drop in trigger for less than $125. There is no appreciable difference between the CMC and the Rise Armament trigger so it's the best overall value in terms of bang for your buck but you should look at adding KNS pins for your install. Given the performance of either of these triggers I would never consider spending more than $150 on a trigger upgrade, but that is just me and a smooth 3.5lb single stage trigger works for my needs, yours may vary.

Take a look at the Rock River two stage triggers offered by AR15Sales.com, they come in clean 4 I/2 and a 3 1/2 bound pulls shipped for less than a hundred dollars. I have three of the 4 1/2 lb. units and they are well worth the money. Haven't found a better deal so far.

The Geissele triggers come mostly assembled. Not as easy as a drop in, but not difficult either. I've installed three of them, including the SSA-E. Will be using one for AR number 4.

+1 for the CMC drop in unit. I installed the 3.5# unit in my Sport last year and love it. Easy install, crisp break and single stage.

I just put in a Gisselle SSA-E in my RRA Predator. The installation was pretty straightforward. See YouTube for specific instructions and details. The trigger pull is not much lighter than the RRA OEM match trigger, but I think the SSA-E would be a big improvement over most AR 15 stock triggers. Willyboy

I have a couple of Velocity Triggers. They drop in and are available in several pull weights. They are NP3 coated. The guy who makes them used to work at Timney.

The preference between single stage and two stage triggers is going to be a personal preference, if one has a preference at all. I don't have a preference myself as long as the pull weight is good and the travel feel is good.

I have a Geisselie SSA in my M&P10 and love it, if that is the price point you are interested in. Timiny and CMC are good suggestions as well.

If you don't want to spend that much, the ALG suggestion is a good one too.

My birthday was a couple of weeks ago. MIDWAY sent me a discount coupon and I used it to buy a AR STONER trigger for my current AR build I am working on. Small world, huh?

I have the Wilson Combat TTU in both my 15 and my 10. It satisfies all of my wants plus has that added automatic safety. Sold on them for sure! $270 I think?

I'm going to be the contrarian here and say that I really like the stock trigger on the M&P-15.

I use my M&P-15 for target shooting at ranges 225 meters or less, self-defense and putting meat on the table when my Savage isn't readily at hand. I am NOT a precision target shooter.

But the way I look at it, if I'm going to drop $240 on a trigger, then I'm already more than half-way towards another AR. And I'd much rather have two ARs with less than ideal triggers than one AR and a box of left-over parts.

Best of both worlds, save some money but still have an excellent, excellent trigger. Geissele G2S.

I'll agree with that option. I put the Geissele SSA-E in my first AR, and the G2S's in the next two. They were on sale at Midway at the time, which made them a better deal.

I put in a 4 lb single stage Timney trigger ... like shooting a complete new rifle

well worth the $

I bought the 3lb version and it is exactly 3.5lbs with the lyman gauge. When I called their tech support, it was actually the owner I spoke to and he kept telling me my gauge was off in spite of the fact it measures my other trigger Geiselle SSA E to 3lbs perfectly.

What's yours at?

;lol...on the half way to another AR but you could also be half way to a better shooter with a better trigger. I have shot mine with the stock trigger and it really gets annoying because the shots tend to have a huge shotgun pattern. Ever since changing out my groups at 100 yards is about the size of a golf ball. Not exactly a moa but for me close enough

Considering a golf ball is 1.680in in size.. I'd say that is very good..

If you consider that distance, and how LITTLE of a movement/change in the riffle position, which would be in the thousandths of an inch to make a projectile impact a fair amount off from the last shot, Yeah, that's nothing to sneeze at..


Were you shooting off a bag, or?

Even if so, If the Stock/rear of the riffle moved even the slightest!, that would greatly effect the point of Impact..

sorry if I am drifting a bit here, but if someone were to plant a dial gauge to the front area of the riffle and another to the stock area, then play back the shot in slow speed, I think it would be surprising how much movement takes place a nano second before the primer is struck, even with a very nice high end trigger.
then if you calculate that movement, by that distance, what may seem like a next to nothing movement, can move the impact around quite a bit..

You called the owner to complain about a +0.5lb variance? Likely he was right, it is your gauge, but either way I doubt you could feel the difference between 3 and 3.5lb in the same trigger. Seem like you just wanted to whine about something. As for the "huge shotgun pattern" with a standard milspec trigger, sounds like you need to practice more.

Go check Mr Gunsngear's review of the M&P Sport 2 and take note of his huge "shotgun pattern" using the standard trigger.

I would. He paid $190 for a 3lb trigger, got a 3.5lb. Ain't like it was a gift. Love the way some of you like to passive aggressively tell people they can't shoot. That make you feel good or something?

I as shooting off a bag with another bag near the rear stock is that legal?...lol.....I am bet if i used a sled i would get MOA...But I am also using PMC XTAC and my Sport II is not floated. On occasion I would get a flier that would go way up or left. I am also using a Vortex Strike Eable 1-6 so its' easier to keep the groups smaller

Well, I called the owner because the trigger says "3.0" and it was not. My Geissile SSA-E using the same lyman gauge registers 3.5lbs as the trigger is advertised so I doubt my gauge is off. I have read others and seen utube where the Velocity Triggers were supposed to be 3.0lbs but were not.

And Arnoob,. truth be told I have never shot my AR15 with a stock trigger because I dump the mil spec even before I go to the range so I have no idea if my shots would be a shotgun pattern. But I do know I do not like the fact the MP Sport II has a lot of creep and it is also a bit heavy. The creep would push my sight picture down and possibly cause body movement. That said, the only triggers that ever been to range was the replacement. I was just estimating that if I used a stock trigger my groups would be loose. I think I could compensate by taking up a lot of the creep and then aiming and shooting but that takes more time

I am not happy about a 3.0lb advertised trigger that is actually 3.5lbs but I am still satisfied because my Geisselie SSA-E is 3.5lbs and twice the price so the $139 I paid for my Velocity I will take that and run. I could send it in to get them to look at it but 3.5lbs is fine. Will I ever buy another Velocity? Maybe maybe not.

If I was buying a trigger for a specific trigger pull weight, it is advertised to be that specific pull weight, and it isn't, I would be unhappy. It's different if it's advertised to be about or withing a certain range, like say an ALG. But if I'm paying $100+ for a trigger advertised to be a specific pull weight, it better pull at that weight.

Well the Velocity is obviously not a top shelf trigger and by me sending it in to get looked at, I feel is only going to lead to more aggravation. The 3.5lb is still not so bad so will just leave it. Had I bought a Geissile different story, I would have been making a fuss

Don't listen to me, like my name says I'm a noob. Whatever makes you happy man, if you don't like the standard trigger more power to you swap it for whatever you like, but stating the standard milspec trigger produces "shotgun pattern" groups is just not a true statement.

I dropped in a Geissele SSA-E...the install was very simple. The hammer pin was a little tricky to get lined up, but the entire process took me less than 10 minutes. I got to test it out today and I have to say, it was money well spent. With the Hornady Black ammo, I was able to get 1 inch spread at a 100 yards. Thanks to everyone for the different options and information!

Thanks for the good read.. I'm sold on the WC/TTU.
