Talked to Richard at BWE a couple of times he’s not really into making to many parts for the MK760 or Smith & Wesson 76

I know the MK760 series had some problems with premature wear on some of the FCG parts, with the sear being one of them... Maybe have a machine shop make one custom for you or just Tig weld the worn area and recut to factory spec? some pics might help also...

Can you xerox it?
If it's just a flat stock, then start w/the pivot pin hole and drill that into 4140 steel. Glue the xerox over it. Cut out the metal an file. Harden w/torch. |

If you have a sample part or a drawing, I can do it.

It's a little more complex - there's a spring retainer - but the problem is that there aren't any drawings available that I've seen. That and the damn things were investment cast. If there were known good measurements - even with the caveat that the trip surface needed to be bulked up and then fine tuned for each gun - I likely would have made a batch by now. They can be made from bar stock with minimal effort - but to what dimensions? |

I don't speak for the OP - but if all I wanted was a one-off I'd have made the replacement myself. I already have done exactly that for multiple parts on mine but those parts were no problem to do a short run. If I'm making some sears I'd like to make enough of a run to pop on GunBroker or similar so that others who need them can buy them too. |

99% of sear issues with MK760's are due to wear of the trigger bar.....normally that's the contact surface that has to be welded up/recut.....
Which one of these does your sear look like, and what is the problem with it?  Might want to try Jim Burgess..... his S&W 76 guns used 100% interchangeable parts with S&W's (with the exception of the bolt) [email protected] http://www.jmbdistribution.com/class3_guns_forsale.htm |
