Amatuers, what mall ninga in his right mind would have that thing. It hasn't got a pistol bayonet, no tacticool light or laser on a rail, no 200x scope, but free shipping, now that is a bargan.
It's not perfected yet. It needs a quick detach button, so that when you enter the "projects" you can quickly remove it from the bottom rail and fit it to the side.
I believe it is meant to be a "quick release carrier mount" for Glock - not to be a firing platform. When the rifle jams/malfunctions, Glock quickly DETACHES from the mount to be put into action as rifle is dropped down on the sling.
Perhaps they thought it might be faster than reaching for the holstered Glock - maybe. I believe in the Israeli tactics and we should rethink this product usage.
