If anyone is still looking for that 22 mag cylinder for a RG model 66 revolver I have one. I am willing to trade it for the 22 LR cylinder. I have two of the mag cylinders and want the 22 LR one for a cheaper way to just have fun with the gun. I have an extra 22 LR cylinder, will trade....taurush@suddenlink.net

Couple of possible reasons- your ammo is a different caliber than the revolver (22 Long Rifle will not fit in a .22 short revolver, nor will .22 Magnum fit in .22 LR) or the cylinder is partially blocked by fouling, rust, etc. Frankly, the RG revolvers are generally of very low quality, I would check the caliber of ammo, clean the cylinder well- and if that does not fix it, I would move on. Value of these is typically lower than an hour of gunsmith time.

Inexpensive revolver made in Germany
