    Perfect size

    They need to be thin like this to fit where they need to be. I do wish they had a HDP or polycarbonate one.

    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.

    This thing does it all. I highly recommend adding one of these to your suppressor tool box.

    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.

    Worth the purchase

    Published by Unknown on 3rd Nov 2020

    I got this for my revolution series suppressor. This fits the piston retainer and is much better than using a wrench and possibly damaging it. When it gets carbon locked a wrench is needed. My only gripe is it's very hard to get leverage because the handle is so short and the part I need is right in the middle of the wrench. Maybe I will try putting the wrench in a vice and turning the suppressor by hand. It also works really well on 3 lugs. Trying to install one without it can be a challenge.

    Multi function wrench

    Published by John on 22nd Jul 2020

    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.
