TX 200 ....

[KeithS]

I have bought a used tx 200 mk3 that had a service before I bought it ...
Now I have shot around 50 shots to settle the gun down but now it has developed an internal wobble !!
or something that needs to be tightened up.
What could it be ?

[eddie666]

do you mean vibration ?
it could be grease in the chamber which will diesel ( ignite and make more power and more vibration ) can you smell burnt oil or see bits of smoke coming out of the barrel,

[Phil B]

I think you need to be specific in describing an internal wobble!

[Roadworthy]

If all stock screws are tight it is possible for the stock mounting bracket to be loose from the barrel. I put Loctite on my bracket as well as the screw threads.

If it's just been serviced, maybe one or more of the stock screws haven't been tightened up correctly. One each side of the fore end and two for the trigger guard.

As suggested, a drop of Loctite on the screws might be a good idea, but make sure it's one of the "low strength" ones such as Loctite 222. After all, you will at some time want to service it again.
