Semi Auto Sear Verification Help

[O1gagt]

I have two sears that I picked up with some other parts. Now that I am looking at them it appears they are Semi Auto Mini or Micro sears... can anyone confirm? Can these be used in a full size semi Auto build? If not are they worth anything?

I really can't see from your pics. From what I know, the Mini and maybe micro have one sear pad sticking up.
Beyond that the difference in how the pad is cut semi vs smg could be shown in this site's reference section and also here

Not sure about a full size semi build, There could be some reason to have 2 equal sear pads for fs. But the bolt / firing pin act similarly fs to mini, but not exactly (parts are different) so dunno.
There is a market for everything parts wise now. so you can definitely trade or sell to get what you need. (gunbroker / reddit). If you have enough 922r parts you can find a fs smg sear and modify to semi. or buy one milled by others.

The picture below is a good start. It doesn’t address the new style versus the old style but that’s not really what you’re asking.… If you want to learn more about that, reference Richard Hoffman’s (BWE) YouTube channel.

Those are mini semi-auto sears. They can be used in a full size semi build as only the left side of the sear engages the striker assembly in both the full size and the mini.
