I am looking to buy a 7w striker series from sanwu. I want to also buy a g7 lens. I don’t know how to change them out. I have a guardian series laser I was trying to see if I could get it’s lens out as a proof of concept. I know your supposed to unscrew it but I can’t because there’s almost nothing to grab onto. But let’s just say I can get it out and replaced with the g7 lens. Will it affect my ability to attach the beam expander?
