How do you remove the barrel from my 7600?

Answer 1

Easy my friend, You just take the sling swivel off the front with a screwdriver and the pump handle plus a small steel washer just pulls off. Under the barrel is a pipe looking thing with 4 holes in it the handle slides on. Find a punch or screwdriver that fits NEATLY into these holes (a good fit is important or you'll wreck the tube). Poke the screwdriver through two of these holes and use it as a spanner to un-screw it (anti-clockwise of course). The thread is long but once it's out the barrel simply pulls out.
