More plastic than steel - AIM Sports AR15 Delta Ring Wrench Removal Tool

The majority of this wrench is made of a hard polymer. Perhaps there is a thin steel rod running through the wrench handle, and into the hook portion which goes into the mag well. Used it a couple of times to swap hand guards and seems durable enough, but time will tell. It doesn't mar the delta ring, which is good. Overall, I'm concerned with the durability of the polymer hook, and can't tell if it's actually reinforced or not. It would be really bad if it snaps while exerting force to pull the ring back. For that, can't recommend. 1 star off for being mostly polymer, and another for false advertisement of all steel construction as stated on their packaging. It's definitely not all steel, far from it.
