I like to store my gun with a gun lock, my question is should i store the weapon with the bolt open or closed? if i close it the lock with be stopping it from fully closing, will this be bad for the rifle? i heard it is bad to keep a bolt open for long periods of time because it puts more tension on the spring. i can't really keep the weapon without a lock because i am temporarily living in a friends house, so i don't have anywhere to store it where i could keep it without a lock. if i did keep it open which spring would i have to replace? just the recoil spring i am assuming?
