For sale: all metal Mossberg Magazine which is marked " S-L-LR ". Made to fire all three .22 rounds, either Shorts. Longs or Long rifle. It has a moveable built in piece on the top at the follower to make the adjustment. It works fine. I believe the clip hold 7 rounds. It fits several different models of Mossberg .22 cal rifles. Please look over the photos and check the magazine to make sure it fits your model. From my research it looks to fit the 340, 342 , 342 and 350 models and possibly others. $83.00 shipped CONUS. PM if interested.
