Brno ZH 204 combo gun barrel fitting help needed.
      14/09/15 06:44 AM

As part of a trade deal I recently obtained a very good condition Brno ZH 204 combo gun in 12G X 7x57R made in 1969. This is the same gun as the 304 but without the crudely etched "engraving" on the receiver. It came with a spare set of 12 gauge barrels. They are marked ZH 101, made in 1960. The spare barrels fit nearly perfectly but the action does not quite close by a millimeter or so (see photos).

My question is: does anyone have any experience fitting these spare shotgun barrel sets and if so what relieving needs to be done? There are various interior bearing surfaces and I'm wondering where a I may need to relieve a surface or two, proceeding slowly until a perfect fit is obtained.
