  1. UZI semi sear need to be hardened?

    OK, Thanks for your input! I had been mulling over in my head the thought of whether or not the SMG sear would be surface hard only or hard all the way through. I just wish I could find someone who KNEW ( from experience or other ) what they were and / or what needed to be done regarding hardening the newly cut semi sear.
  2. Hello, Im new here. I have recently been collecting parts for a semi only UZI build. I have a few more parts I need to buy. MY Question IS: If I have a smg sear cut on a mill by a machine shop, would the newly cut semi sear need to hardned before use or woul it be good to go as is?
