Frequently Asked Questions

How do you install a Wilson Combat TTU trigger on an AR-15?

Begin by clearing the firearm. Remove the upper receiver, then the standard trigger components. Install the self-contained Wilson Combat TTU by aligning its pins with the receiver holes and securing them. Finally, reattach the upper receiver and perform a function check.

What is the difference between a single-stage and two-stage Wilson Combat TTU?

A single-stage TTU provides a continuous pull to fire. A two-stage TTU has an initial lighter pull followed by a second, crisper stage before hammer release. Installation is similar, but the two-stage requires the hammer to be open before housing the unit.

What tools are needed to install a Wilson Combat TTU?

The primary tool required for installing the Wilson Combat TTU is a punch. This is used to remove and install the hammer and trigger pins that secure the trigger unit within the AR-15 lower receiver.

Why is a function check important after installing a new trigger?

A function check is critical after installing a new trigger like the Wilson Combat TTU to ensure safety and reliability. It verifies that the hammer releases correctly, the disconnector engages and releases properly, and the safety mechanism functions as intended.
