I see some FT clubs require them but don't see any actual specs for them. Is it basically a brightly colored trimmer line that runs from breech to muzzle to prove you airgun is unloaded? Would appreciate a pic of one on your rifle if you have one.
Ok thanks guys, that’s not so bad then if you just have to insert it few inches then. I was thinking it would be a hassle having to thread the line all the way through the breech and barrel until it exited the the muzzle.
