Thanks I’ll check it out.
Don't remove the tube and fire the gun without a tube in it!
It will ruin the threads in the end of your barrel. Take you tube out and read what it says on it...XF F M IC Cyl.
XF is extra full, it is a very tight pattern. Cyl is no choke restriction at all and a wide pattern.
You may want to get an IC ( improved cylinder) tube for close range shooting, but never fire the gun without one of the various tubes installed because it will ruin the tube threads and render you barrel worthless.
