#1 best upgrade for your mp5 or clone - UTG Pro Extended Picatinny Claw Mount for MP5 / MP5K

Once mounted, and torqued to spec, this rail becomes one with your gun. I mounted a Scalarworks 1.57” riser, with an Aimpoint ACRO C-2, and it’s solid! Like welded on solid. The rail itself is very low profile, and does not interfere with the iron sights at all. The only thing that I can’t quite figure out is, my Vortex magnifier, with a QD mount, will not go on. Am I missing something? Operator error? I’m at a loss, on that one. But, in the end, I can’t fault UTG with this minor issue. 5/5 stars! Easily! Don’t waste money on anything else! This thing is perfect.
