I repaired a friends' CD autoloader, (he never cleaned it or read the manual on how to take it apart), and once I got it cleaned and the gas piston fixed, I was very pleasantly surprised at how well it shot. Not fancy, but seemed like a good deal for a first autoloader. My oldest son shot it extremely well. No malfunctions in 150 rounds I shot after I repaired it, and hulls ejected briskly.
