I found this at a garage sale a few years ago. Fired it with GP11 (?) Swiss surplus ammo a few times. At 100yds got about a 4" group 6"high and 4" left. Stuck it in the closet and almost forgot I had it. A month ago I got it out and figured I would investigate what the modification at the muzzle was all about. I always thought it was just threaded and the sleeve was to protect the threads.
Turns out the sleeve is a tight slip on configuration. the bore is counter bored in to where the two cone shaped holes are placed at 3 & 9 o'clock. The sleeve is tapered so it will only go on one way. As you can see from the pics the stock has also been modified but not just hacked off. Also in the last pic is a vinyl strip with the name +E.L.ZEA+ placed just in front of the butt plate.
Looking for ideas of what this modification could be for, JohnAttachment 223149Attachment 223150Attachment 223151Attachment 223152
