Things I liked: Really like the weight, and the fact it's all metal. Feels real comfortable to shoot. Especially like the magazines that hold 16 rounds.
Things I would have changed: Don't like the fact that the sights front and rear are fixed. Would definitely benefit from a moveable rear sight. The one I have is really, really off. And I have to compensate every shot because of that.
What others should know: I've found up to this point that the Diablo Basics seem to work best for me. I tried Beeman H & N Match wadcutters, fall out of the clip. Too small to stay in the holes of the clip. So when you use up 8 shots on one side; when you flip the clip around for the other 8 several will have fallen out.
Things I liked: Product is great. Made well, and does what it is made for.
Things I would have changed: Can't think of anything really that I would change, except the pouch that you get to keep it in. Rather cheap, could have been a little better quality rather than a thin piece of plastic.
What others should know: I had no problem with it fitting in the barrel of my air rifles. And unlike some that have made comments; I rotated mine around in a circle in the barrel and didn't experience any of the elliptical pattern some spoke of. It rotated absolutely true to the spot it was pointed at.
