As a newbie to the VEPR game, I wasn't really sure where to look for conversion parts to make it 922r etc... I wouldn't hesitate to go through Carolina Shooting Supply if you are looking for parts. No affiliation, just a happy customer hoping to maybe help out someone like myself. Will post pics soon of the finished product, even though most of the parts are internal and are already installed. Sadly no range report yet, but everything looked great and the parts I got were excellent.
