STX Barrel Breach o-ring

[Jnewood]

Frustration has officially set in!!! I can't get my FX Dynamic to stop blowing breach orings in the barrel. I am replacing it every time I go shooting. How can I prevent this??????

A little more information might be helpful....such as caliber, shooting slugs or pellets, any modifications, worked on recently, did it do this from new....etc.

I bought the rifle used

Sounds like the probe could have a sharp edge, or isn't aligned with the bore properly.

What bore size slug are you using. What pressure. Are these official fx, 70-90d and correct size ? Is it FX or aftermarket tp/inlet?

Be careful of Amazon o-rings. Buy from somewhere reputable like oringsandmore. You could also try stepping up to a 90d. I had the same problem with Amazon crap, poor tolerances.
