Tougher than it looks - Real Avid Smart-Fit AR15 Vise Block

I looked at a plastic magazine vise block which looked somewhat hollow or flimsy. I was pleasantly surprised when I received it. This thing is tough. The polymer is solid and heavy and it locks my AR-15 into place perfectly with only two turns of the handle. Even the places that "look" hollow are extremely solid. I had a no mar block before which loosely fit my rifle and pistol, but now, with this thing, I don't have to worry about it slipping a bit. The little plastic add-on tool is also cool too for cleaning, but probably better with a cleaning rod. Buy it, you wont be disappointed.
