No 4 Rear Sight Disassembly Help

[Zeb]

I have a '42 LB. I want to install a recently purchased PH5C. The rear sight axis pin is locked/held in place with a small pin on the left side of the receiver.

I need some advice/tips on how to remove this tiny pin.

So far I have bent the smallest brass pin punch I own. I don't want to scar the receiver by using a steel pin punch.....but I'm running out of options.

One question.....this pin needs to be removed from bottom to top....right? (when rifle is sitting upright in bench vise, the pin needs to be drifted from low to high ???).

The lower part of the pin that points towards the safety looks pointed and is difficult to get any sort of traction on.

Any suggestions ?

I used a bench grinder to reduce the size of the tip of a spare steel punch I have. I carefully use it to drift the retaining pin upward a bit, then I grab it with pliers and pull it out.

I have used a mechanic's "dental pick 90 degree" to pull up on the pin till I could grab it with pliers. Mine moved fairly easily though.

small steel punch,,, nothin to it,,, bottom up untill you can grab it with plyers or visegrip

I just took mine out with the same concerns. I used a wooden dowel then I made it a bit pointy and tapped it with a hammer. It worked great and no worry of scratching the metal.

Don't lose it, because it's made of Unobtainium! Mine is held in by a very little piece of copper wire.

Not to hijack your thread but I used a fine tip flat screwdriver, placed it in the groove, and gently pushed mine up. If you lose yours, buy a pack of 3/4" finish nails, chuck one into a drill and use a swiss file and fine sandpaper to make a duplicate. Too easy!

wrap the pinpunch with masking tape. if you need a new one a small finishing nail is an almost perfect fit. i have a small box of them just for this

opps i see the finishing nail isnt my idea only

I've seen a couple of those pins that were an absolute #####. Broke off punches, total frustration.

Seen others you could push out with your fingers practically.

First thing I do is remove the safety assembly to get a better angle on it. I have some long, skinny pin punches that are good for that job, but if it is peened over and jammed in there...

Piano wire of the same diameter cut to length works wonders if you ever lose that little pin.
