Exclusive Wilson Combat engineering enables a durable, 4 lb., ultra-crisp trigger pull without any fine tuning or adjustment. Reduced, positive trigger reset guarantees a quick follow up shot on target. The unique hammer geometry enhances reliable ignition with military and surplus ammunition of all types while a 1911 style half-cock notch allows the TTU to meet or exceed military specifications for drop safety. Pre-assembled, CNC machined trigger housing contains H13 heat-treated trigger, hammer, sear and a stainless steel spring for trouble-free installation. Bullet Proof designed and extensively tested by shooters for shooters, the new Tactical Trigger Unit has raised the bar for drop-in AR triggers.

Wilson Combat AR-15 Tactical Trigger units will reliably function in any standard USGI style AR style lower receiver with standard GI trigger pins of .154” diameter regardless of caliber, including 7.62/.308 length AR receivers.  

  • Colt brand rifles made for commercial use between 1991 and 2009 will generally have a proprietary trigger pin size of .169” and are not compatible with any Wilson TTU.  
  • Colt rifles produced with pinned-in sear blocks are not compatible with any Wilson TTU.
  • Wilson Combat TTU is not compatible with the Bushmaster ACR.
  • The MR556 and any other AR style rifle with a firing pin safety mechanism in the bolt carrier is only compatible with the TTU 3G (TR-TTU-3G)or Two Stage Models (TR-TTU-M2).
  • With .22 LR AR conversions or complete .22LR caliber  AR-pattern rifles it is recommended that the standard single stage TTU (TR-TTU) or two stage TTU (TR-TTU-M2) trigger be used along with high or hyper-velocity ammunition for best reliability.
  • The TTU is compatible with the S&W MP-10 .308 AR but the rifle's ambidextrous bolt catch must first be removed to install the trigger unit.

Because of the short, fast reset of the TTU, always use a firm grip and solid hold when shooting from the bench or prone to ensure that bump firing does not occur.

Great trigger for an HK
I had a competitor trigger that starts with G. in my HK. It wasn’t that much better than the stock trigger. I bought one of these and I liked it quite a bit better. Will be buying another for my other HK.
the best
Have this trigger on two rifles and is amazing. Long range excellent, run and gun excellent. Breaks like a glass rod and short positive reset. Couldnt ask for more. When I can afford will get a third for my last rifle. Have tried the rest and then sold on ebay.
S&W 15-22 with TR-TTU-M2 LOVES ELEY Yellow Box .22s!
According to the Wilson Combat TTU website: “With … complete .22LR caliber AR-pattern rifles it is recommended that the standard single stage TTU TR-TTU or two stage TTU TR-TTU-M2 trigger be used along with high or hyper-velocity ammunition for best reliability.” I installed a TR-TTU-M2 trigger in my S&W M&P 15-22. I shot the gun in 50 foot indoor bench rest club competition for 10 weeks. I fired a total of 140 rounds of .22 Long Rifle 40 Grain Lead Round Nose Eley Yellow Box Target Ammunition, Muzzle Velocity 1085 fps. I had ZERO FAILURES of ANY KIND, EXCEPT: My best match score was a 92/100 with 6X. How can anybody hit 6/10 X and score 92 you may ask? Well, I was 77 years old and only competing for the second year and …??? Oh, Yeah! What everybody else wrote AND trigger is GREAT!
I have at least 6 of these trigger groups!
The first three rifles that I purchased were Bushmaster Varminters. These two had 2 stage Frank White design triggers. Having experienced the feel of the standard military or production triggers, I decided that all of my AR builds would have 2 stage triggers in them. I wanted a wholly contained trigger group that would eliminate pin walk or rotation and found Wilson Combat TTU-M2 trigger unit was what I seemed to be looking for. Im really impressed by the design! The primary sear being on an extension of the hammer and the secondary sear on the bottom of the hammer. In my opinion and that of others who have shot my rifles, these triggers are great. I now know just when my rifles are going to fire. No more contemplation of just when the rifle is going to fire. Take up the first stage, then concentrate on the sights. Im sold on these triggers. I also use Wilson Combat parts in my 1911. Ive never had any problems. They also back up what they manufacture. Thanks Wilson Combat!
Awesome Trigger Pull, Super Easy to Insall
Wow, I bought two TTU-M2s to upgrade both my S&W M&P 15, and also my DPMS Oracle AR-10. My DPMS had a terrible factory trigger pull, and my S&Ws factory pull was very average and ordinary. But boy oh boy, both have nice crisp and smooth trigger pulls now. The TTU-M2 makes both rifles so much easier to shoot. I was really impressed how easy the unit is to install too. It was childs play, really. I highly recommend this trigger.
No doubt, the very best.
Got my trigger unit and had it in the rifle extremely fast and easy. What a sweet piece of engineering. Cant wait to see what it does to my 6.8SPC groups. Great people to deal with, I have used their 1911 components for years, first time on rifle. Not last though.
Just installed in my Stag lower, took 3 mins, because I took my time, WOW. I just built upper with a Wilson Combat barrel. First time at a short range and .5 MOA at 100 yards with 55gr PMC. Cant wait to get to the long range with some Match ammo. Def worth every penny. Nick and the rest of WC are exceptional and his advice was dead on....
2-Stage trigger review
I recently purchased and installed a WC 2-stage trigger assembly in my AR. Installation was straight forward and quick. I did a side-by-side comparison once installed against the Geissele trigger in my other build and Ive got to say, the Wilson Combat trigger wins hands down! Great product, easy installation and exceptional service.
finishing touch on an ar-15
i have owned firearms since i was 9 yrs old. im now 63. i have customized various firearms but have never worried about the trigger unit until now. i own a bushmaster ar-15 that i have tricked out some but wanted to go farther and completely finish the firearm and this trigger unit has really impressed me i absolutely love the pull and action of this unit. now long range shooting with this 20 inch bbl bushmaster will be a dream. it was already very accurate but now there will be absolute dead on shooting. you cant go wrong with these products,very pleased. happy shooting! it will be for me.
Great trigger
I am not mechanically inclined but I had no trouble installing this trigger. After installing on a Sig 716 my groups improved immediately. The trigger has half of the pull weight of the original trigger which is over 7 lbs. Looking forward to another trip to the range. It breaks clean and has no creep or overtravel that I can feel.
Nice and Crisp
Love the feel of the two-stage trigger, the mushy feel of mil-spec trigger is gone. Definitely recommend.
Great AR Trigger
Installation was very easy and the trigger is extremely smooth. Will be putting these in all my future AR builds.
Easy install, Instructions were perfect. Crisp smooth trigger. Fast delivery!
comp 2 stage AR trigger
Excellent product. Crisp light trigger release. Took 5 min to install. Pins were a little difficult to line up on reassembly but not too bad. Best way to seriously improve accuracy with you AR
Awesome Trigger
I have never had a trigger other than stock OMG this trigger is incredible, It breaks so crisp with very little effort, my groups are now less than an inch apart!!! highly recommend it.
Great trigger
I own several Wilson 2 stage triggers and I felt it time to comment. They are, simply, great. Easy to install and a gem within the rifle. I appreciate the simplicity and durability of the unit. Be confident in the fact that they user non-adjustable. They dont need to be. As perfect a product as Ive ever owned. Match it to a Wilson, or any other top quality barrel, and - simply - never look back.
2 Stage TTU
Excellent product. Crisp light trigger release. Took 5 min to install. Pins were a little difficult to line up on reassembly but not too bad. Best way to seriously improve accuracy with you AR
Clean and Crisp
Installed the TTU on my new Colt MP4 today. What a difference a good trigger makes and this is a great one! Easy to install with quality fit and finish. Buy one and watch your groups shrink. Far better than the factory trigger.
Best Upgrade for your AR!
I just bought my first AR on a budget. My first upgrade was this TTU 2-stage trigger. After the ten minute installation, I headed to the range. Now, my groups are as tight as my range buddies with their high dollar ARs. Ive had it installed for a few months, and it performs like a champ. Worth every dollar. I have no regrets about this purchase.
Fastest Trigger Job Ever!
Thanks again Wilson Combat! This is my third TTU and my first match version. The two-stage pull is perfect and the let-off is exquisite. I dont know how you do it, but keep doing it!
Two Stage Match Trigger
Thanks again Wilson Combat! This is my third TTU and my first match version. The two-stage pull is perfect and the let-off is exquisite. I dont know how you do it, but keep doing it! FORGOT TO ADD THAT I JUST PURCHASED MY FOURTH TTU!
A solid tactical 2-Stage
This trigger is setup on my 3Gun rifle and it is amazing. It is slightly heavier than my Jewel two-stage that I have on my high power service rifle ARs, but a Jewel trigger isnt tactical, the TTU is. Installation was rather straight forward, though I had to really push it down to get the lower pin-hole to align installation time: 5min. The trigger design is absolutely superb. The trigger comes assembled and truely drop-in ready, while the design allows a reliability rate that would imho be mil-spec or above. There are a lot of triggers out there, but some designs increase the chances a malfunction if the gun is abused or used outside of normal range conditions. This trigger is a typical two-stage with a very brief take up, then a crisp break on the second stage. The Army Marksmanship Unit AMU guys that teach SDM at Ft. Benning use two stage triggers on their guns and for a good reason: two-stage triggers can improve your shooting. The two stage allows the shooter to place pressure on the trigger and time exactly when the weapon is fired. By having the initial pressure on the trigger you can eliminate the bump that can occur from going from no pressure to firing on a single stage. Rapid firing is fast as the trigger resets very quickly and catching the trigger will turn it into a single stage for rapid fire drills. I will say that I still get some trigger freeze trying to shoot more than 5 rounds of rapid fire. Pretty much I just need to time my trigger movement with my shooting speed. If your looking for a reliable trigger that has match grade performance this is the trigger for you.
Great 2-stage trigger
Installation was easy. Short take up. Second stage breaks clean. I will be getting one for my other rifle. Thanks Wilson Combat!
Best Ever
First 2-Stage trigger I have purchased from Wilson. Will certainly buy more. Easy to install and works very smooth. Light, concise pull. Great product!! I highly reccommend.
Easiest Trigger job! EVER!!
I installed the Wilson TTU M2 in my AR15 a couple days ago, all I have to say is WOW!! It went in like it was made for MY AR. Installed, it makes shooting my AR like shooting a match rifle. A crisp break, like a glass rod breaking. No slop, no over travel, just BANG when I pull the trigger. Thank you Wilson for making a great product!!
5-Star Tactical Trigger System
This great product has it all! Fairly priced; easy to install. I needed to do the additional step of removing and reinstallation of the safe/fire selector lever on my DPMS AR-15 to complete the easy install. Great hunting trigger.

Sweet, smooth pull-A good value!
Great Trigger, Super Easy install, no problems. Ignites everything...the two stage has a short, smooth takeup that is super crisp with a strong reset. I like the fact that it is self-contained for cleaning and maintenance. Great job WC! I feel like this trigger is a good value since I could easily install myself on the kitchen table!
