Exclusive Wilson Combat engineering enables a durable, 5 - 5 3/4 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.

best upgrade for my AR
When I rebuilt my AR I didnt go cheap this time. I replaced the major components with quality parts like BAD lightweight barrel, SAI BCG, captured buffer spring BAD enhanced pins. When the TTU mil/le arrived it dropped into the AR and installation was 100% easier than a non-modular unit. Trigger reset is better than any other trigger I have tried POF, CMMG, mil-spec I have let my buddies shoot this AR and each one of them have ordered some type of TTU trigger. The MIL/LE is perfect for the type of shooting I do. Its crisp, reset is awesome, travel is short. I highly recommend this trigger!!!
Have installed TTUs in two of my ARs. Absolutely the easiest and best triggers that I have ever used!! Which is what I would expect from a Wilson product. Great triggers. Well worth the bucks. Thanks
Excellent Design, but not compatible with Sig 716 .308
Ive purchased and used 6 of these wonderful triggers. I love a good single-stage trigger. Through a recent experience, Ive learned that Wilson Combat did not test this trigger in the Sig 716 rifle. The Sig 716 is a mass produced .308 AR platform rifle made in the USA with more sold than all other .308 AR platform rifles. Unfortunately, this trigger is absolutely not compatible with the Sig 716. Before you order, be certain to ask Wilson Combat if they have tested this trigger with the rifle you plan to use it for.
Crisp, clean, no c....
After watching the install video provided on WC website this trigger went in to my DPMS LR243 with ease. This trigger installs and functions as described. CRISP, CLEAN, NO CREEP. Highly recommend.
great trigger
this is my first wilson combat purchase and first drop in trigger and it works great. nice and crisp, perfect fit and function in my spikes lower w/ kns pins. i will be getting another for my 300 blackout setup soon
Perfect for gloves or cold weather.
Got my new TTU LE-MIL and it dropped right in with zero issues in 2 minutes..perfect trigger pull for my duty rifle, especially when wearing gloves or in cold weather. One thing i really like about the TTU as opposed to the G trigger is that the modular construction makes cleaning a snap. A+++ Wilson!
