Superior STX liner

[igolfat8]

I purchased a .22 barrel kit and it came with a Superior liner. I was pretty surprised. There was no info on the tube and I didn’t know it was a Superior until I took it out and cleaned it. Boy was it filthy and lots of brown rusty gunk came out of it. Never seen that brown junk in any other FX barrels before.

I wish I could bore scope one of the new ones. I was shocked by what I found in my original 600mm pellet liner. Thankfully, FX USA replaced it...
