Impact barrel o-rings, Confused

Drumsnguns · Feb 9, 2018

Ok I was cleaning my Impact .25’s barrel and noticed that there appears to be an o-ring groove inside the barrel on the muzzle side of the TP but no O-ring. I looked at the schematic but didn’t help since there is no barrel in the drawing. I took a photo of it. The left side of the photo represents the muzzle end. Can anyone help. If there is one, then what size?
The o-oring at the breech end is in place.
Thanks,
KP

Is it a thimble barrel so you can index the barrel?

The barrel is notched so it can only go in one way so that the Transfer Port lines up with the barrel.

There is only one oring inside the barrel. I think your looking at the joint between the brass section and the steel barrel. The barrel screws up inside the brass section. The pellet is pushed just past that joint by the probe and the oring seal is just behind the TP.

Thanks for the reply. Sure looked like an o-ring groove. My bad.
