I suggest Buffalo Arms as a source for these sights. Enter the Part Number in their search box.

Sight Width

As noted in the chart above the .340 sight width fit the width of the Rossi dovetail. The other sight width is .531" which will overhang the width of the Rossi Dovetail.

Fitting Marbles sight to pre-Braztech dovetail

The pre-Braztech dovetails appear to maintain the same 60° slots, the cut depth is just slightly deeper. I wanted to put a new Marbles front sight on an Rossi/Interarms 62 to complement a Skinner Peep sight. I masked a "band" across the width of the slot and applied a bead of JB Weld. After drying the required time, it can be filed if needed. The sight slid in dovetail with the appropriate pressure and makes a great addition to an accurate classic rifle!

I thought my experience with Marbles sights might be helpful to others.

I replaced my Rossi 92 (.357 mag) sights with he Bullseye Ghost ring and their fiber optic front post. The rear sight is the long version (2.5 inches) and the front fiber optic (green) is .530 inches. Best I can tell, I'm shooting the Hornady 140 grain Leverevolution 2 inches high at 50 yards. The Bullseye Ghost ring is set on the 2nd elevation notch on the ramp. The fiber optic front sight is a 3/32" bead and functional for hunting, but don't expect precision target shooting from it. I'm able to put 5 shots into a 4 inch square at 50 yards, hand held, from a seated position using my knee as a rest for my elbow. IMHO - good for a heart lung shot out to 100 yards.

I haven't been here in a while and just saw this. That chart is a very handy and useful resource to have, thanks!

Great write up. Like the photos.

No kidding.........believe it or not Ripley !

Apparently the JB Weld & Crazy Glue attachments are competent enough to hold together on parts that aren't under the direct pressure or load of firing and are standing the long term test of time & recoil in RDs guns.
Obviously hot temperatures don't effect the welded/glued parts.........Texas weather can be quite hot.
My only concern in regards to the hunting/survival theaters I play/work in is the effect of very cold temperatures where some glues & epoxies will harden & crystallize and then crack under recoil.
I'm not saying the joined parts wouldn't hold up in sub zero weather I'm just saying that to my knowledge there is not enough field experience to indicate one way or the other.

Only one way to find out.

I used JB Weld inside a deep freeze once. As far as I know it's still holding.

Michael, you can send that 480 up here to Montana for the winter. I'll be happy to test the JB weld for ya. Just for testing purposes, of course! DP

[Ranch Dog]

I'll ask it if it wants to go. It might not want to get that cold! That's a good thought, "I don't want to go where JB don't want to hold!"

I want to make sure it was understood that I did not epoxy the front sight in place. I used the JB Weld to reduce the depth of the dovetail slot. After it cured, I filed the surface of the JB flat and the 3/8 fit like it was supposed to. The sight can be drifted as needed. It is a great cure for a chronic problem with pre-Braztech dovetail slots.
