Hi.. I'm making a mk18 clone and I was wondering if the Daniel Defense DDM4/ SLiM/ Lite Rail III Hardware Pack work with this rail? thanks Expert Answer

I liked it by Buck, August 31, 2020
Pretty easy to install with proper tools. Machined well. The receiver and hand guard rails line up perfect. I like how the anti roll/twist feature of the guard is machined into the guard. Weight is good.

Love Midwest Industries by TwoToneT, Verified Owner, January 17, 2026
I’ve used several Midwest Industries rails for various builds. However this lates uses a Wilson Combat bullet upper and the anti-rotation tabs do not allow the hand guard to work with this thicker receiver. Just something to note. Will still use them...
