I've got an Air Arms TX200 MkIII I recently bought from Pyramyd Air in .177. It's my first airgun so I figured I'd do it right so that if I didn't enjoy shooting it, I couldn't blame the equipment. I fitted it up with a 12x SWFA scope in an RWS mount with 27MOA elevation built in. All up it weighs about 11 pounds.
Pros: fit and finish are excellent, easily the equal of a new production Winchester Model 70 or CZ 550. The polishing and bluing are nearly perfect and the wood to metal fit is very close. Mine has the beech stock and the laser cut checkering is attractive and does its job. The contrasting grip cap is a nice "California Style" touch. I couldn't find any plastic on the gun, other than the rubber buttplate. The stock is well proportioned and set up perfectly for using a scope in higher mounts. My eye lines up right behind the 12x in the RWS mount.
The trigger is fantastic. I haven't adjusted mine because I feel no need to; it breaks crisply after a very short first stage which makes it easy to settle on target.
Accuracy is quite good. I am getting 3/8" 5-shot groups at 20 meters with the JSB pellets, shot off the bench.
The internal baffles bring the sound down to about the level of a small nail gun.
Cons: it's a heavy gun, no argument there. But I haven't found it to be hold sensitive at all. The cocking effort is a bit high as well, which can make shooting more than 20 pellets in a sitting a bit of a chore, but that's the nature of a powerful spring gun.
All in all I've been happy with it, but I'm thinking my next gun will be a pre-charged pneumatic. I've got a SCUBA tank already so there's not much more I'd need. Don't know whether I'll hold on to this AA TX200, but I don't regret having bought it. Never hurts to learn on quality guns.
