Wilson Combat Trttu Tactical Trigger Unit Single-Stage Steel Black

The Wilson Combat TRTTU Tactical Trigger Unit is a drop-in AR-15 trigger designed for a crisp, reliable single-stage break. It delivers a 4 lb trigger pull with no tuning required and a reduced, positive reset for quicker follow-up shots. The TTU is a pre-assembled CNC-machined trigger housing consisting of an H13 heat-treated trigger, hammer, sear, and a stainless steel spring to simplify installation. It is intended to function in any standard AR-15 style lower with GI trigger pins of .154 diameter and is compatible with calibers including 7.62/308-length AR receivers. Note: The TTU can be installed in the S&W MP-10 .308 AR; however, the rifle’s ambidextrous bolt catch must be removed first.
