Sterling Mk6 trigger

[Vincent]

Yes, it’s the magazine catch spring. It doesn’t do anything that I can tell. Just put there by someone who didn’t know where it really belongs. I am sure you have seen “crunchies” do similar things.

The engineers at Sterling did a very good job of making the Mk4 almost impossible to assemble wrong. I guess you can never prevent this level of…. er, “creativity.”
