You never appreciate this tool until you've had to remove/install AR hand-guards without one. This will work until I find one that's all-metal but for the casual user it's ok.
Nice and not to f**k up your AR
Yes you can make your own, but for $10 you get a good quality tool made just for the purpose. It will be an in-often used tool in my AR kit but an important one when you need it!
Great tool to have in the box. Only down side is the package say's it is all metal. It is not. The hook is plastic. I used a strong magnet to check. It stuck to everything but. Also hook finish scratches off.
Delta Ring Wrench
These are great to have around. I have taken my hand guards on and off without them, and it's not fun.
Very easy to use. There is no risk of damage to the rifle. Can be used without an assistant ! Durable.
