How do you properly secure a barrel in a vise.

5thumbs · Oct 5, 2021

I tried to remove the shroud on my Impact M3. I've done it before and it simply requires rotating the shroud in a counter clockwise manner. This time it unscrewed the transfer port connections to the outer sleeve of the barrel. I cant get a good grip on that sleeve to rotate off the shroud now. I know there is no locktite. I have a vice with flat "jaws", how can I use this to safely grip the exterior of the barrel housing so I can rotate the shroud off without damaging the barrel? It is not as robust as other barrels I have seen. Or is there another technique to do this? Thanks.

Wrap it in leather or rubber and tighten it just enough so it doesn't spin. An old belt or an inner tube will werq in a pinch.

Look on Amazon for some ( magnetic soft jaws for a bench vise ) they have different options . Since I started air guns they have been very handy .

you really need the right jaws for it to do it right .. it would be best imo to have someone mill you same jaw inserts out of nylon or maybe copper with the proper groove cut in it to hold round stock ...

I use one of those rubber strap wrenches or a golf glove

Thank you for the input. I was not able to get the rubber strap wrench to work. So I ordered some vice adaptors (rubberized and with grooves) to give it a try. Thanks for your help!

Another option if you have the means is to get two blocks of wood and drill a hole down between the two.

I went to Harbor Fright and pickup the CENTRAL FORGE 2-3/4 in. Articulated Vacuum Vise for $18. I used it to change out all my liner to heavy with the Carbon Fiber Liner Sleeve. Wrap the clapping surface area with electrical tape for better grip.

Thanks to everyone for all the advice. I ordered a set of rubber vice inserts, and a set of hard plastic vice inserts with a notch and the they worked. Still wrapped the outer barrel with a rubbery material and just slowly tightened until it allowed me to remove the shroud. Was having some accuracy issues and after I took things apart, cleaned the barrel, worked on properly reassembling the liner/transfer port end/grab nut/CF sleeve/shroud/moderator, I got my accuracy back and maybe a bit more. Mission accomplished!!!

Spent almost as much as the harbor freight vice shown above which looks really good.
