winchester 69a sight question
i recently bought a 69a with a couple of problems i need to work out. first, it was drilled and tapped for a two piece scope mount and the front mount (on the barrel) has the front screw stripped. is it possible to retapp this hole to a slightly larger size, maybe metric? also both front and rear sights are missing. the barrel has 3/8 dovetails. i have a .290 high front sight and plan on buying a folding rear sight. what height rear sight should i buy? choices seem to be .360, .460, and .520? as always thanks in advance for your help.

There is a device called a Helicoil. It's a tapped hollow screw about one size larger than the existing hole. A destroyed tapped screw hole can be drilled out and tapped to the next larger size and a helicoil inserted which returns the original tapped hole to its original dimensions. Sights in various sizes can be obtained from Brownells. 0 -
could someone tell me how to determine what heigth rear sight i will need for a .290 front sight. also i wasn't aware the made heli coils that small but i will see what i can find. 0 -
The factory height ft is .290 and the rear is one of those slotted step adj ones looking at Numrich. Maybe you can find a good picture of a complete rifle and scale the rear off the front. If it were mine I would drill/tap to a larger size then take a nail and die to the new size at 95% thread engaugement, install and pean. Lastly redrill and tap to correct origional size. Touch up with cold blue. If nothing else get the middle folder and try. A spare rear sight laying is that expensive. 0
