Reviewer: Chuck J
Nowhere did the description say the upper was made of polymer. Oh well, after opening the box, I decided to try it anyway. As suspected, it wouldn't hold a zero and the slightest pressure anywhere on the upper affects the strike of the round. As is, it's junk unless you want a gun for plinking and the accuracy is not important. I ended up buying an aluminum upper, and the Chiappa barrel and other parts easily transfer over to it.
