Easy to install/practical

Paired perfect with my new OLIGHT PL X giving an ambidextrous feel yet compact enough to keep everything streamlined.

Stellar Manufacturing

The Tri-Rail is VERY well machined, and takes seconds to install. This is a no-brainer addition from an American manufacturer that will last a lifetime.
I now have multiple DT items on my 590A1.
Phenomenal customer service. Just do it!

So much room for accessories

Got a light, a touchpad and a sling mount on this thing!

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.
