So I really like how solid these things mount up to the rifle.
But the screws from M-Lok Accessories do hit the clamping area. Like it is really tight in there. Sadly part of the reason I dimpled the aluminum is because of the stupid thread locker magpul puts on every screw. Makes it hard to tell if I'm hitting resistance or just trying to tighten it againt the hardened goop they use.
These were with the screws that came with a Magpul Picatinny Rail. I tried even some of the shorter ones with a few accessories and ended up having to file them down. Sadly I buggered up one of the slots too. Even the side slots are pretty close tolerance wise. Unable to use a Magpul brand light mount out of the box without filing down the screws.
Decided to go with a different hand-guard/optic mount.
I would love to have a rail that has Picatinny at the 6 o'clock, but M-lok on everything else. The Mlok Logo/UM on the bottom could of been another half slot too.
Love your products, I'm not trying to poo-poo them.
