Yep, definitely a poly barrel!
Interesting that theTPs' are so small, the .22 HP barrel TP is 5mm and 4.5mm in the breech, I would have expected closer to 6mm for a .25.
I wonder if that has been done to suit the lower power restriction for where the gun was shipped to? smaller TP's would give much better ES on a lower power gun though.
What power is your gun producing and what are the program parameters do you know?
