royden Posted January 13 Report Share Posted January 13 I have a problem with my Vulcan carbine in as much that the barrel moves off face after firing just a few shots and loses power. A tap on the muzzle puts it right for a few more shots then the same thing happens. It has never had open sights on it as long as i have owned it and i have been told by one or two that the barrel was originally glued into the breech block .I was wondering if the two grub screws that hold the rear sight base in place actually fix the barrel as well. If the barrel is just bonded in place any ideas what adhesive was or could be used.? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
snarepeg Posted January 13 Report Share Posted January 13 I dont think the rear sight screws hold it? if you can remove the barrel. Clean it and inside your block use JB weld it should hold fine, make sure your barrel is fully flush with cylinder face as when it sets, it sets very strongly. 👍😊 Quote Link to comment Share on other sites More sharing options...

oldypigeonpopper Posted January 14 Report Share Posted January 14 Hello, Looking at the Vulcan parts diagram i think the barrel has worked loose in housing or breach, You could drill and tap some studs in or as mention glue in with JB weld Quote Link to comment Share on other sites More sharing options...
old man Posted January 14 Report Share Posted January 14 Studs would give revereseability, JB not so? Quote Link to comment Share on other sites More sharing options...
royden Posted Wednesday at 10:31 Author Report Share Posted Wednesday at 10:31 I did consider drilling and tapping to fit some grub screws but i went out and bought some JB weld as suggested and decided to go this way. If it moves after this then i will get it on the pillar drill. Thanks for the suggestions chaps and i will let you know how i get on.

London Best Posted Wednesday at 12:04 Report Share Posted Wednesday at 12:04 Don’t even consider butchering the gun on a drill. Not necessary. I have never used JB weld. In the engineering industry, Loctite Studlock is the stuff. And the application of heat will remove it if necessary. Quote Link to comment Share on other sites More sharing options...
