Works Great!

Easy way to add a rail to my new Mossberg! Make sure your magazine cap nut is tight then just put this over the top and tighten down the nut! Held solid for me through several rounds of buckshot. I’m looking forward to my next DT product.

Super easy install, quality part, great service from Defender Tactical.

Must Have!!!

This is a must have item!!! Look, fit, and feel is perfect! Extremely well made! Fits better than most factory parts! Highly recommend! 5 Stars!!!

Top shelf

I’m glad I waited to find this product, this is top shelf. The ease of installation and the options with the three mounts, is fantastic. I mounted the Olight Balder Pro R. This is by far top a top of the line set up.

Shockwave 12

Quick shipping. Easy installation along secure fit. Was able to install Crimson Trace w/ red laser and light on bottom as I intended. Very good product for the 12 gauge Shockwave.
