Benjamin 312 Screw Specs?
« on: November 13, 2021, 03:24:38 PM »
Hello,
I'm a new member who recently picked up a 1962 Benjamin 312.  I though it would be a good idea to reseal it and that led to quite a mess, now I'm putting it back together and it appears I'm both missing three screws and have an extra one which I can't figure out where it goes. 

It seems no matter how careful I am this sort of thing seem to happen!

The screws I'm missing are both the breech cap screws and the bolt guide screw (tried to post links to both online but as a newbie I can't post links yet).  I'm wondering if anyone knows the specs on these screws so I can find non-original parts/screws to use to get this gun back together and use it?

I've included a pic of the screw which has no home at the moment.

Any help/pointers are appreciated.

Thank you for helping me,
Drew

Your pictured screw I'm pretty sure, is to hold the safety on.  Maybe your safety is missing or got lost on the workbench?
The breech cap screws are 2-56 X 3/16 oval head which won't be easy to find.
The bolt guide screw is a specialty item, not a normal screw.

The best plan is to get factory parts.  Two sources who may have what you need are:
Mike Baker at peter_built78@hotmail.com 
or Rick Willnecker via www.airgunshop.net
