I thought that you all might be interested in a little project that I tackled last night in the shop!

A fellow asked me to put a Marble full buckhorn rear sight on his Model 92 Puma rifle. The dovetail on the factory sight was much larger than on the replacement sight, so I had to do some creative splicing!

The factory sight dovetail was riveted to the sight blade, so I just drilled out the rivet and separated the two parts.

Next I had to grind and file off the integral dovetail of the Marbles sight. I used light colored spray primer to paint the top of the sight, then I scribed layout lines in the paint. I used hand files to shape and fit the Marbles sight into the Puma dovetail block. I had to modify to dovetail block so that the Marbles sight sat deeper into it. Once everything looked okay, I went ahead and use Force 44 low temperature silver solder to fuse the two pieces together.


Finally I cleaned and dressed the solder joint. I used cold blue to touch up the file markes. I oiled the sight and drove it home on the barrel.

That is my story and I am sticking to it!

Nice work and good thinking. Got those grey cells working did yah....lol

I used the Force 44 to tighten up my gas tube, was a little loose put some Force 44 on the rear angle and it's tight. The stuff blues too. Just wish Brownell's had something a little harder but as easy as Force 44 is.

Yes sir! Force 44 is pretty soft, but then it is very low temperature solder. I guess that you could use high temperature solder (silver braze). I think that the melting/flow point is 1500 degrees F.

Nice job,

It looks like it was born there.

I use Brownell's Fusion.
It's 1145 degree, so it's legal for muzzle attachments, yet doesn't require as much heat as the 1500 degree stuff.

7.62 X 39,

What color is the steel when the 1145 degree "Fusion" solder from Brownell's begin to flow? I am thinking about getting some of this stuff! Do you use their flux too?

Fusion is a premixed solder, the flux is mixed in. Also the problem with Fusion (silver solder) is that it won't take bluing or phosphate.

Your right, I didn't stop to think about that.

Where I'm using it on a muzzle brake, that is not a problem.
But on a application such as this, it would be.

you can use gunkote GUNMETAL BLUE and paint the sight.

It is a pretty close match to factory bluing.

You can paint over ANY metal.
