This is the feed mechanism go 6mm plastic balls,I need to stop the balls rolling forward out the barrel before I fire!anyone have any ideas?

The simplest would be to take a nail and hammer and make a tiny tiny tiny little dent in the brass tube. Tiny.

Yep thanks!i almost tried with a nail punch but didn't want ruin a barrel in case it didn't work well now that you've suggested it I'll give it a go!thanks again

Make sure it's Tiny! do it one little tap at a time, it's easy to overdo.
