Solid mount

I wanted a way to mount a Bull Dot (makes shooting from the hip and actually hitting your target a breeze) for my Shockwave. All the other mounts I found looked like bent, flimsy metal or over complicated rail systems that I had no interest in. This mount exudes quality and was a piece of cake to mount. Put the Bull Dot right where I wanted it and also allowed the use of my sling. This is the 3rd item I've bought from DT and I love every single 1 of them. Patiently waiting for a heat shield and probably something else I didn't even know I needed. Lol!

Awesome well made piece

Easy install and very well made product. Nice fit and function.

Great customer service!

Due to my own lack of attention I lost/misplaced the swivel stud that mounts this kit. I emailed DefenderTactical about getting a replacement. The very same evening I received a response that they would happily send me a replacement at no charge. In summary the quality and fit of this kit is great, but the customer service is awesome!
