    Great Wrench

    Published by K on 22nd May 2023

    Got this wrench for tightening a flash hider onto a jam nut for a PTR-32. Almost no shoulder on the barrel threads required a jam nut. This wrench was thin enough to fit on the flash hider only without interfering with the jam nut.

    Irritated that I had to buy a third armorers wrench, I was looking to find an inexpensive wrench for timing my muzzle break. I needed a thin wrench and this one met my needs. It’s quality made and the right price. Thanks guys.

    This is a quality tool. Especially considering the price. Griffin also goes the extra mile and packages it nicely. You can tell when a company takes some pride in their work and it shows in this tool.

    Good fitment on gun parts. Needed this to get between shims and muzzle brake. Can't beat the price for this tool.

    Did what I needed

    Published by Unknown on 4th Feb 2021

    I bought this to install a surefire muzzle device. Surefire has their wrench adapted but it’s been sold out for a long time and a crowfoot is too wide for the wrench slots on the device. Griffins tool had the right size wrench opening and give how narrow it was, it fit on the slots with ease. I haven’t used it for it’s other features and functionality but at this price I’m fine with that. Most wrench’s are well over $50.
