Wilson Combat AR-15 Single-Stage Tactical Trigger Unit

An all-new single-stage trigger unit that is easily user installed in any AR pattern rifle in less than 1 minute. 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. Bullet Proof designed and extensively tested by shooters for shooters, the new Tactical Trigger Unit has raised the bar for drop-in AR triggers.

Note:

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.
