go to www.skanline.com they got pics there....they are great barrels itz like a freak in that itz versatile but the inserts are only about 2.5" long but that doesn't seem to matter cause they shoot great.

I have an ANS super cocker ( one of ANS' first custom cockers ) and it has one of the 3-D barrels one it. I am not fimilar with ANS making a barrel with the inserts, but the barrel I have sucks. I would get a different one as quickly as you can. And if they are still made the same way, DONT lose the barrel plug, because the I.D. of the end of the barrel is larger then other barrels. You'll see what I am talking about if they are the same.
