Gew 88 Sporter barrel question

[jmoore]

Salt Flat, old time gunsmiths doing sporter conversions on these rifles back in the day usually cut off the threads on the barrel shroud and slipped this down over the barrel shank to cover the threads on the front of the receiver ring.

One of those things that's so obvious it's easy to miss. That's my excuse. Plus it's probably been ten years since I last pulled the shroud from either of the '88s on hand.
