Things I liked: I am not disappointed. This is a beautiful rifle. It's worth the cost merely as an art object, the fact that it is also such a fine rifle is a bonus. Walnut stock is gorgeous. The metal is too but I need to stop obsessing about how easy it is to get fingerprints on it (yes, I do clean it after shooting.) Only ran a few hundred pellets through it so far but I am really happy that I chose this rifle. I got used to loading and cocking it very quickly and find it quite easy to do.
Things I would have changed: As others have said - it is heavy. I also really wish you could re-engage the safety, doesn't make sense to me why you wouldn't be able to. I also wish Air Arms would design a way to add a sling - I know you can attach something to the cocking lever but that does not seem like a good (or safe) solution to me. A finely made rifle like this deserves to have a finely designed and well made option for a sling, not something jury-rigged.
What others should know: So far seems to like RWS Meisterkulgen pellets the best. Also tried Crosman Premier, JSB Diablo, RWS Superdome and Air Arms Falcons but the Meisterkulgen were the most tight and consistent groups. That may change after the rifle is more broken-in? Time will tell.
Things I liked: It protects my rifle and keeps it clean. It was only 50 bucks.
Things I would have changed: This is not a well made case. The latches don't work well and feel like they will not last long. The plastic is cheap (i.e. thin) and the foam easily comes loose. It doesn't seal well (not sure it seals at all - I wouldn't want this case to get wet.) If I had seen this case in person I would not have bought it. At least it wasn't expensive. I am used to higher quality cases for other equipment that I have. It's fine for now but I will eventually get a "real" case...
Things I liked: It is easier to grab hold of the underlever and cock the TX200 with this. I am glad I got it. Especially if you have larger hands, if your hands are cold or if you are wearing gloves. It fits exactly like it should (as you would expect.)
Things I would have changed: The machining could be a little better to more closely match the TX200 finish quality - This is the only reason why I am giving 4 rather than 5 stars.
