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.
