Wilson Combat TRTTUH2 Tactical Trigger Unit Two-Stage Howe Steel Black

The Wilson Combat TRTTUH2 or simply referred to as TTU, is a cutting-edge, single-stage trigger unit that you can conveniently install in any AR pattern rifle within a minute. Its effective design by Wilson Combat promises a robust, 4lb, ultra-sharp trigger pull, with no need for meticulous tuning or adjustments. The TTU assures a reduced, positive trigger reset for a swift follow-up shot on targets.

This product's unique hammer design increases dependable ignition with various types of military and surplus ammunition. It also includes a 1911 style half-cock notch, allowing the TTU to either meet or surpass military standards for drop safety. The TTU comes in a pre-assembled, CNC-machined trigger housing including H13 heat-treated trigger, hammer, sear, and a resilient stainless-steel spring for a hassle-free installation process.

Designed with precision and rigorously tested, the Tactical Trigger Unit has set a new standard for drop-in AR triggers. Wilson Combat AR-15 Tactical Trigger Units will function reliably in all standard USgi style AR-style lower receivers with regular GI trigger pins of .154" diameter - this applies to all calibers including 7.62/.308 length AR receivers. Meanwhile, they are not compatible with Colt brand rifles produced for commercial use between 1991 and 2009 as these usually have a proprietary trigger pin size of .169", any Colt rifles with pinned-in sear blocks, or the Bushmaster ACR.

The Wilson Combat TTU will only be compatible with the MR556 and other AR style rifles that have a firing pin safety mechanism in the bolt carrier when you utilize the TTU 3G (TR-TTU-3G) or Two-Stage Models (TR-TTU-M2). In instances where .22LR AR conversions or complete .22LR caliber AR-pattern rifles are used, it is advisable to use the standard single-stage TTU (TR-TTU) or two-stage TTU (TR-TTU-M2) trigger with high or hyper-velocity ammunition for utmost reliability. Lastly, the TTU can operate with the S&W MP-10 .308 AR, but the rifle's ambidextrous bolt catch needs to be removed prior to trigger installation.
