Timney Triggers are one of the best investments you can make in your AR-15 rifle.

Timney's trigger upgrade will provide you with a smooth, consistent and predictable single stage trigger break. By eliminating the slack and inconsistent break a standard trigger gives you, the action feels more similar to a traditional bolt action than a combat rifle. If your accuracy suffers wide target groups, this drop-in trigger can help shrink group sizes.

Drop-in triggers require no gunsmithing, fitting or adjustment. It simply installs using your rifle's original hammer/trigger pins; Timney's proprietary design eliminates pin walkout, which can weaken your receiver walls.

The default weight is set to three pounds at the factory, but can also be adjusted to four or four and a half pounds. When using a .22LR conversion kit you may want to go with a four pound or higher trigger pull.

NOTE: For use in a polymer lower, a special plate is required which can be obtained directly from Timney at (623) 223-1111.

"Purchased this trigger and love it. Took no time installing into my Bushmaster lower. Took out to the field to shoot, and found the disconnector was locking the hammer back even when trigger was pulled.Easy fix, there is a screw you can adjust the disconnector to get it to fire correctly, with a bit of Loc-Tite and it fires flawless."

"I just installed this Timney 3lb ar-15 trigger group into my CMMG lower, on which I use an Alexander Arms 6.5 Grendel 19.5\" barrelled upper. I am no Camp Perry Champion, but I have been shooting and reloading and competing for years and I can feel zero creep in this trigger group. There is no take-up either. The release is ultra crisp, the reset is quick and precise. In summary, better than I expected after reading some other reviews."

"I bought this trigger after countless hours at the range trying to dial in my Bushmaster. It seemed no matter what ammo I used the accuracy was marginal at best. After installation (10 minutes) I went to the range. I should have purchased this trigger when I got the rifle. It now has the trigger pull and the accuracy of a varmint rifle. If you like to shoot your AR you will love it after you install this trigger."

"This was a great addition to my Bushmaster Carbon 15. The stock trigger was mushy with a gritty feel. Hard to get good groups with such a trigger. The Timney was easy to install and breaks like the proverbial glass rod. It was definitely worth the price."

"This is a very nice drop in trigger. Easy to install, breaks crisply and no malfunctions yet. My only complaint, it isn't adjustable."

"I'm not sure what the deal is with my situaction, but the trigger will not drop in low enough into the lower of my Bushmaster to allow the trigger/hammer pins to be alighned?I was on the phone with Kevin (3times) of Timney, and he advised me to tap it into the lower (slight punch marks now on the trigger), then the pins did tap in (nicking the bushings slightly). But it wouldn't funtion? Again Kevin advised me to heat up the set screw to loosin the loc-tite, and adjust it. I did this, and after adjusting it 3 times, ever so slight from 1 end to the other in adjustment, it still doesn't work. CTD won't take it back because I've altered it as per tech and printed instructions. Timney says send it to them (my $ ) and they'll try it? At this point I've lost confidence in this trigger, and I'm out off $200 + tax. This ain't no squirrel gun, it has a more important purpose! If You buy it, and have trouble, best to return it. I suspect the trigger is slightly too wide or my reciver is slightly too narrow, either binds the group so the hammer won't throw?"

"I have installed Timney 3# small pin AR-15 drop-in triggers into 3 Bushmasters and 1 Stag Arms carbine rifles and never had a problem both with the installations and functioning thereafter. For the money they are probably the best and give long-term repeatable reliability in operation. One just has to follow their written instructions with attention to what you are doing and installation should not be any problem."

"Very easy to install. Works great. The only down fall is that you will end up spending a lot more on ammo because it is so much fun to shoot. This will make you a much better shooter. I am using a Smith & Wesson M&P-15 with iron sights, and I am keyholing the crap out of the target at 50 yards. I am getting another one for my M&P 15-22. Really good stuff. A must have."

"This is a great trigger group. My AR now feels better than my trusty old Rem 700 - crisp, clean, and no travel. Now I have to get one for the 700. Helped to increased accuracy at long ranges."

"Only four bullets cause i havnt fired it yet but installed like a dream 15 min tops went right in my Bushmaster no problem. The pull is crisp, clean and way better than the stock 8 pound pull."

"Popped this into my Colt AR-15 A2 HBAR that I bought in the late '80s. It's always been a great rifle but had a rather \"crunchy\" trigger. What a difference this trigger makes! I took it to the range yesterday and hit nearly everything I aimed at. I still need to see how it does on a paper target but I'm sure it will be impressive!Installation was very easy although the small locking screws were a bit tricky to get past the springs. It made a big difference in what was already a fine rifle. I couldn't recommend it more."

"great trigger if the bolt action feel is what your going for. timney is known for great triggers 1 warning before you buy make sure your trigger pins are the right size. when you install make sure you torque down on the set screws if you are not buying a set of anti drift pins. the trigger has a crisp clean break with no take up. trigger reset is clean and audible. easy install. but if set screws are not torqued down trigger will rock back and forth and give you a bump fire and possibly loose a trigger pin. recommend blue locktite on set screws if not already there."

"DO NOT try to install this trigger in a Colt H-BAR type AR since it did not fit mine. Colt has a block in the lower housing that will prevent the trigger from going into position. After the failed attempt on the Colt, I installed it into a Bushmaster AR and it went in just fine. No problems, except I have not had a chance to test the trigger, and that is the reason for the 4 bullets (probably not fair since everyone else has given it great reviews). It does seem to operate just fine, but I'm still not convinced a different trigger will make that much difference in the accuracy. I hope so."

"I have helped a lot of people install other triggers, but besides the easy installation, this trigger is a shooter's absolute dream. EXTREMELY CRISP if you like the precision feel. This is my latest of many Timney triggers. All my long guns will have them eventually."

"This thing is solid. I had mine in in less than 30 minutes while chasing a 2yr old. Take your time, follow the directions and you shouldn't have any issues with installing it. It works just as advertised. Single stage and it breaks clean, minimal reset. A trigger upgrade should always be one of the first things you do to a rifle."

"Bought this for my Sr-556 Ruger Ordered it. Price was very competitive. Delivery was quick. Watched a video on you tube for a couple of minutes. Got to work at it and was done in 20min. Not bad for a red faced old fat man with failing eyesight and the shakes. I can tell by dry firing it that it's going to be awesome. Crisp and light. Taking it to the field in the next couple of days. Can't wait."

"After reading reviews I thought this trigger would be better, to me pulls harder tha 3 lbs, haven't put a gage on it, and has to much travel and doesn't seem smooth or break like it should. I've been reading reviews from all over and I see I'm not alone on this."

"Installed today on my new Ruger AR-556. Easy install after watching You Tube video. Feels great. Breaks like thin ice. Can't wait to get to the range."

"In a word...Sweet! Just put it in my Barrett REC 6.8 spc. Good, tight fit. Relatively easy if you read the instructions, and follow them. The break of the trigger is just right. Night and day over the old unit. Can not wait to get to the range!"

"Absolutely the best AR15 trigger for the price. Dropped this trigger in my Bushmaster lower mil-spec receiver, so easy. Light, crisp action adds accuracy to my rifle for superb scope shots. HIGHLY RECOMEND...!"

"Night and day difference from stock trigger on my DPMS Bull 24. Crisp and clean. Perfect for all around bench and hunting. May be a tight heavy for precision target shooting, but that's not why I bought it. I needed a new trigger with minimal creep, and this one does great. Already improved the MOA which was already very good. EASY drop in trigger took me 5 minutes to install."
