Helpful Positive Review Great product poor Shipping Package by Miguel Diaz, Verified Owner, October 15, 2023
The MDT arca rail is good but the shipping was very bad. Please, if you can, send this in a cardboard box and not in a plastic envelope. I received the product with a few scratches and I don't have time to return it now.

Helpful Positive Review Installed on MDT XRS Chassis by wildcatgoal, Verified Owner, October 14, 2020
Installed the longest one on my MDT XRS chassis which I use (with the Savage sitting inside of it) in PRS Tactical class. Once installed, it's never budged and is holding up well. The supplied hardware seems to be high quality and doesn't strip.

Helpful Positive Review Howa Oryx replacement part by Pfdr, July 28, 2020
Bought for a Howa Oryx, too long of a wait for the mdt part. Great fit and finish. Works like a dream with an atlas bi-pod. Arca is a must have! Picitinny and keymod have their place but that is not on my hobby gun. Fit and install fast and painless.
