I have an H&R topper that I'm making into a light pack gun, use dura enamel to re-coat it, as she was pretty rusty on the outside, but no pitting. I want a better sight system than just a bead, something like a rib and two beads. I figure a rib is a little much so I was thinking of soldering some version of an express sight, nothing real precise, just sort of a crescent. So you can tell me alternatives but steer away "why bother,it's a shotgun" type comments, and you can tell me the problems with soldering and how I should go about it, any different than standard soldering?

Soldering on a gun barrel requires:
1. Proper metal prep (it must be clean & bare steel with a slight rough texture. That can be done with 240 emery paper.
2. A proper solder & compatible flux.
I would recommend a Stay-Brite low temp silver solder kit.

3. A heat source.
Probably a good propane torch would suffice.

A. Sand area of barrel that will be soldered with 220 grit sandpaper.
B. Flux sight and barrel mounting spot.
C. Using a propane torch, heat the area on the barrel. (Stay-Brite flows at 450 degrees)
D. After the flux has boiled and the solder begins to flow, tin the barrel and sight base with the solder.
E. Position sight on the barrel and clamp into place.
F. Re-heat until solder melts and flows into the joint.
G. Remove heat and allow to air cool for several minutes allowing the solder to harden. H. Remove clamp and check solder.
I. When joint looks good with solder showing on both sides, you are ready for the next step which is clean-up.
J. Use hot soap & water to scrub all the flux off.
K. Excess solder can be scraped down to bare steel with the edge of a sharp knife..
L. Finish gun as desired.

Or, glue it on with Lock-Tite Black Max and be done with it.

Also does anyone have experience with acra gel from brownells, and if this is a good application?

[rcmodel]

Yes, I have used Acra-Glas for bedding & stock repair for at least 45 years.
Gluing sights on would not be a good application for it.

As I said, L-T Black-Max is great for gluing on ribs and other stuff.

but steer away "why bother,it's a shotgun" type comments,I'm sorry, but I just can't help myself.

If you plan to use the gun as a shotgun, all you need at most is a brass bead front sight.

It is doubtful, even with rifled slugs, that express sights would extend your range any.
And they would be counter-productive for shotgun shooting on moving targets like birds & rabbits and such.

Dang RC,

You're good.

well xs, has a scope mount set up that recommends acraglass as a way to adhere the mount to the barrel, so I asked. And they put sights on lots of shotguns, for a reason, even ones that are not meant for shooting sabot slugs, I am simply considering adding an unobtrusive means to make a slightly more precise sight system, just as most double guns have a rib, and many have a second bead to align a shot.

In the case of the XS rail, acraglas is used as much as a space filler as an adhesive. As an adhesive, it also has much more surface area to work with.
