Hello,

I recently purchased a Colt 6520 Gov't A2 and the pin to secure the sear block, fell out.  It's the pin that has the large circle, on both sides of the lower receiver, and it's in 2 pieces.

Any recommendations or a gunsmith, on how or who can fix this issue?  Would I be able to send it back and have Colt fix it?  I've reached out to the Braceman, unfortunately, ADCO and John Thomas are unable to help.

Thank you

Can't you just remove the block now that the pin is broken? That is what I would try.

Yes.  However, I want to find a way for the hole to be filled.

Maybe find a couple of flathead screws with heads that match the hole sizes. Cut the screws down, tap the holes, screw in with thread locking compound.

I would just epoxy them back in place.

I would contact Compass Lake Engineering and/or U.S. Anodizing.  I had both companies work some sear block magic on a Colt 6830 lower receiver.  Details can be found in this old thread:
