[Kos-Mos]

If you have not yet understood that, this forum is proning respect.

You have asked for help regarding an issue, stating that you wanted to keep you gun clean.

A well respected member informed you that there was no issue related to having the bolt cover open. Your gun would not be dirtier than when it is closed.

If you don't agree, there is some nicier ways to reply and formulate your opposition.

This is not a good start here, I can assure you.

Your problem has been answered. You have to change the whole bolt cover for any aftermarket/new one.

If you want to find one used, you can get age verified and look in the classifieds. There is always some for sale for very cheap. If you are looking for a new one, airsoftparts.ca is a good start. You could also order it from oversea if you are not afraid of online transactions.
