Standard Heatshield Installation Guide

Step 1: Begin by removing the barrel from the shotgun. Once removed widen the front clamp on the front of the heatshield 1/8” and slide the heatshield over the barrel and slide to the rear. Bend the rear tabs to clamp tightly onto the barrel using a cloth to prevent scratches on the heatshield.

Step 2: After reinstalling the barrel, slide the heatshield so that it touches the receiver, except on the Winchester which needs to be kept ½” from the receiver.

Step 3: Tighten the front clamp around the barrel.

Step 4: Install the provided (2) 6-32 x ¾” socket head cap screws and hex nuts and tighten securely.
Note: Slide the forend to check for any interference between the forend and the heatshield. File tabs or forend as required.
