I got my Euroarms used 45 Hawken today, pics to follow soon. I checked it over and it seems ok except for one issue. The cock rotates a small amount on the tumbler shaft. I removed the screw and cleaned and oiled the lock and carefully reset the screw. It helped but there is still a little looseness on the square tumbler cock axle connection.
I've been very careful to not over tighten and have done nothing else while I'm soaking the lock, cleanout screw, and nipple in gun oil for a couple of days before attempting disassembly and checking the lock properly. The cock and the square axle connection look normal and are not wallowed out and there is almost no indication the lock has been struck very often. There are no witness rubbing marks either and the cock screw had no marks of any kind.
Is this a common occurrence and not to be overly concerned about? If not acceptable what can be done to tighten it up without buying parts
