GunParts corp has themPicked up a nice 504 today. Now I've read both pro and con these, but decided to buy it anyway. This one is in 95%+ condition, will put a Leupold 2X7 rimfire on it to start and try a varity of ammo through it hopefully on Wed. Came with only 1 magazine and I would like to find a couple more if possible. Does anyone have any idea where a spare or spares might be located? Thanks in advance for any help.
