Hi guys a chap at work has picked up a bsa mercury. It's in good overall condition but the barrel has a little vertical movement. He wants to replace the barrel detent spring but is at a loss of how to get it out. So the question is... how do you remove it. I'm guessing knocking out a retaining pin???
Thanks for any help...

Cheers mate. I will pass the info on..
Hi i recently bought a mk2 mercury that had a bit of virtical movement in the barral and when i stripped it down the groove thats machined into the barrel that locates into the pin when you shut the barrel had been machined slightly to deep from the factory and the detent plunger was fine as i swapped it out of my mercury s just to make sure it made no difference so while the barrel was off i just put a run of weld along the half round groove and reshaped it with a rotary file in my dremel then when i put it back together again its now perfect i hope this helps
cheers Andy
