Ya I actually just Found this out today! Pretty excited about it thank you51colt said:There are no illegal rim fire rifle stocks in Ca. Folding stocks are also ok on rim fire rifles as long as the rifle is atleast 26 inches with the stock folded. Ca assault weapon laws only pertain to center fire rifles. box magazines have to be ten rounds or less pistol grips, front grips and flash hiders are all ok in ca on rim fire rifles.
