Upgrading your AR-15 with a WOT Trigger (Wide Open Trigger) can dramatically improve your firing speed and overall shooting experience. If you’re an AR builder looking to install this popular forced reset trigger yourself, this step-by-step guide will walk you through the process safely and efficiently.

Before starting, ensure that the WOT Trigger is legal in your area and that you have the proper tools and knowledge to handle firearm components.

  • Punch set

  • Small hammer or mallet

  • Needle-nose pliers

  • Screwdrivers (flat and Phillips)
