Hello, in the late 1990s I purchased the gold-plated trigger version of the TX200 from Jim Maccari, with a Maccari tune and spring. Haven't shot much in recent years but when I have, I've experienced significant shifts in POI. The other day I did some shooting and could not penetrate the cover of a hardcover book at 15 yards. When I first got it, fps using Crosman Premier lights was about 960 fps (enough to get through wooden boards).
Is there a best person/company out there who repairs and tunes TX200's? Recommendations would be greatly appreciated. Thank you in advance.
PS - I'm located in Georgia
Unless there is some kind of internal damage to the gun, this is an easy job you can handle yourself in about one hour. Order a 13 ftlbs. kit or a full power kit from Air Rifle Headquarters (Jim Maccari) and install it. I just did mine about a month ago. Probably the easiest airgun to work on. No special tools needed.
Thanks guys. You made it sound so easy I decided to check out some videos on the subject. Though mechanically inept, I went ahead and disassembled the gun. Mystery solved. The plastic piece at the end of the piston had essentially disintegrated. So I need to order a replacement for that and clean out the compression tube. I am going to assume the spring is okay, since I've only put about 2000 rounds through the gun in 20 years. Curious thing: there was no tophat.
Yea what he said. One of mine was new when I serviced it a I had a hard time getting the tophat out. I ended up spraying WD40 down on it and letting it sit for an hour...it came right out. Yours has been sitting a lot longer. If your gun has been sitting for years, you may want to order a new spring for it anyway (20.00) if you replace the seal and it turns out you need a spring also, for 20 bucks you won't have to wait. Old srings take a set even if they are not under tension.
I did as people suggested, but I am telling you: there is no tophat. I can tell this just by looking inside the piston, but just to be sure I soaked it in WD40, let it sit for an hour and tapped it repeatedly on wood. No tophat.
Edited: three hours of soaking later, out came the tophat. Was about the give up. Sorry for any confusion, it DID have a tophat. Like they were welded together or something.

The top hat is almost certainly in there. It's just stuck with old grease. Maccari has some very good seals for the TX, I prefer the Apex Small seal, e-mail him and see if he has any of the old blue colored ones. Didn't read the post where you found the top hat. An easy way to tell is the bottom inside of the piston should measure about 110 mm to the rear edge of the piston. I've had a couple that were really stubborn, so I measured and found 95 mm, and yes it was in there. Very easy to work on, other than the stuck top hat.
