FX Impact end of barrel?

Could any of you nice fine gentlemen take a picture of the last 4-6 inches of your barrel lol.....If your minds weren't in the gutter you would know I mean a Impact barrel. I am specifically looking for a picture of a fixed shroud version. The picture I would like is with the shroud off the gun showing the barrel and whatever is attached at the muzzle end.

I am curios if there are different versions made as mine looks to have a pressed/clamped on end. Thanks for any help.
