Plain BBL Shotgun Bead Re-Mount

[roo_ster]

Howdy:

My Rem 1100 has an 18" plain bbl cut down from an original fixed choke bbl. The gunsmith installed a shotgun bead with a rather large base in the cut-down bbl that goes all the way through the bbl.

Well, I was shooting the other week when it came off / backed out / whatever.

The threads were still intact and I later cleaned it off with a degreaser and re-installed it using blue loctite.

My question is this:
What are my options if the bead comes out, again?

Obviously, the blue loctite will have failed and something more / different is required. I was thinking go through the clean/degrease step, install dry, and then use my plumbing torch to silver solder it, hoping the solder is sucked into the threads via capillary action.

Any other ideas?

Cleaned & degreased with Loctite should hold it.

I would not try to silver-solder it unless you use low-temp silver solder like Force-44 or Stay-Brite that melts at under 500 degrees..

Normal hi-temp silver solder melts and flows at 1,200+ degrees, just barely under the temp that will melt or weaken the brass bead.

In any case, the flux necessary to do either will take all the bluing off the barrel around the sight.

Loc-Tite makes a product called "Black Max".
It is a high temperature, high tensile strength, epoxy based adhesive.

The stuff is strong enough that I have used it to repair vent ribs that have popped loose.

It will hold the bead in place well enough that should you ever decide to replace it you will need to drill the bead post out.

You can get Black Max through Brownells. HTH

Well, the Blue Loctite did not hold.

Black Max is what I will try next.

I would suspect there is something wrong with the threads the gunsmith put in the barrel.

Shotgun beads are not that hard to keep in place when properly installed and tightened.

99% of them that are lost break off flush with the barrel & leave the threaded part in the hole. Coming unscrewed & falling out is not normal at all.

I have never seen a screwed in bead come out. FWIW, it is normal to drill through the barrel to install a sight; shotgun barrels are too thin to drill partway through like a thicker rifle barrel, and pressure out at the end of the shotgun barrel is so low that the bead should never blow out. I can only think that the gunsmith somehow either messed up the drill and tap job or used a bead of the wrong size for the hole.

(FWIW, many factory beads are not screwed in at all; they have a tapered base that is just tapped in and stays by friction.)

If you had the work done and know the gunsmith, take the gun back and get him to fix it. One of the glues might work, but do NOT try to solder it or you will ruin the blue.
