Size L2 (5 Slots), max overall length of 2.50". Mounting screw center-to-center of 1.2".
Made in U.S.A.
I purchased three of these for my Magpul MOE stock on my mid-length gas 16" barreled upper. Two are for the sides for my hand stops (Gear Sector) and the top one is for my light mount (Gear Sector for a Surefire G2X).
These go on very tightly and do not move once installed correctly. They come with all the hardware to install them on MOE hand guards.
Once mounted, I installed the Gear Sector hand stops on either side of my hand guard and the light mount on the top. They are lighter than metal and _very_ tough. More than tough enough for the heaviest gear I would consider mounting on my rifle. They are Magpul tough. 'Nuff said.
One thing I am going to do, though, is remove them and Duracoat them the same color as my FDE Magpul hand guard. Either that color or coyote to brown to break up the lines a bit. I paint all my gear in camo colors.
Would I buy these again? Hell, yes!
Would I recommend them to a friend. Again, hell, yes!
