Just perfect

The hardest part for me was getting the old screw on my takedown loosened. After I got that off it was 30 seconds to screw this adapter on. Sits in a great spot; no issues working the pump.

It took like 5 minutes to install the dual rail adapter on my Maverick 88. Now, I just got to figure out what to attach to it, lol.
Love it!!!

Installation was quick and easy. I mounted one of my pistol lights. It works great and is easily accessible. Still need to shoot it with the light mounted, but don’t expect any issues.

Fits perfectly on my Maverick 88. Very solid, no wobble, and feels like a quality product. Mounted a streamlight Big-Face light onto the rails with no issue. Thank You, Defender Tactical!!
