    Griffin Multi-Function Wrench review

    Published by Kevin on 1st Feb 2022

    I purchased a Griffin Multi-Function Wrench to install several 3 lug adapters and it performed incredibly well. Afterwards, I tested the bottle opener multiple times to drink a few ice cold Sam Adams beers and once again this tool worked flawlessly. A great tool provided by a superb company!

    Great tool for the range kit. One of the few three lug wrenches I found online. Product arrived promptly.

    Don’t go to the range without one

    Published by Robin on 20th Dec 2020

    A solid, well made tool. I use the one included with my Optimus 9 on my work bench but wanted one to keep in my range tool kit. Easy to do at $10. A good value.

    Multi function wrench

    I bought it specifically for the tri lug part of the wrench. It works. Finish is a little rough, but it works and I liked the cheap price.

    Great utility. I used it for the tri lug function. Could be longer to increase torque forces, but got the job done.

    Only one came with my Bushwhacker 46 and I needed a second to help take the 3-lug out of the booster. Works great!

    Griffin Revolution Wrench

    Published by Preston on 21st May 2020

    Does what it is supposed to plus a few other things. Not bad for the price...

    If you have one of the Revolution Suppressors you really need two of these wrenches. Revo has several threaded pieces and just like a nut and bolt you need two wrenches to loosen tightened pieces from each other. Like removing a stuck piston from a piston housing. It does the job. It probably would’ve been best to include two wrenches with each suppressor, but tools don’t always come with products...
