Sten MK 2 legal will not fire semi auto ( point me in the right direc

[PilotDave]

Firearm runs perfect full auto with selector pushed in full to the left and right I assume there is a worn part not catching the bolt assembly Anyone that can link me to proper past discussions so i can begin to trouble shoot will be appreciated If I can not fix I do have a good gunsmith in town of you can give me some items to check Also any past message board references from great educated folks on the Sten you can recommend will be appreciated At age 72 I have given up knowing everything!!!

[PilotDave]

Reading great messages it appears I need to 1. take apart triggers group and make sure it was assembled correctly and 2. BUY and good disconnector So any other advice including where to buy a good disconnector appreciated

APEX Gun Parts still has the disconnectors in stock:

Thank you richard I will order then learn to take it apart !

I also ordered a milled sear to be on the safe side I will let folks know what I discover was wrong At our local gun range can only shoot semi auto

Milled sears aren't infallible. The result was a jammed gun and the end of the shooting session. Now I always have spare parts on hand.
