The TTU M2 trigger offers an impressive pull of between 4 - 4.5 lbs. without any need for alteration or tweaking. This reliable and sturdy trigger can be relied upon to provide reliability when you need it most! It also has a reduced reset for rapid follow up shots and its unique hammer geometry ensures reliable firing with all types of military and surplus ammo. Plus it meets or exceeds drop safety standards due to its 1911-style half-cock notch. 

Constructed with H13 heat-treated trigger hammer sear and a stainless steel spring for straightforward installment our pre-assembled CNC machined housing will ensure bulletproof reliability. Developed by shooters for shooters after rigorous tests the Tactical Trigger Unit has firmly established itself as one of the best drop-in AR triggers available on the market today.

Compatibility Notes:

• 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 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.
