Not going to argue about it, Jenning's are just poorly made. Its obvious. And they use inferior materials. They won't kaboom, they just fall apart.
Might add, if your interested a cheap, accurate, reliable, and well made .22 automatic, the Pheonix Arms HP22 is a better choice. Never had a problem with the one that we have laying around.. probably the only gun I forget to clean, since I usually just keep it loaded for a rabbit(its that accurate).
