Hi All. First post here. I just purchased on GB what was described as a NIB 5" field barrel for a Model 41. After examining it in detail, and reading and rereading many of the threads here regarding the field barrels, it appears mine is a 70s model cut down from a 7" barrel - it has the regular ampersand, little symbols on each side of "22 long rifle ctg", machined off weight plug with screw slot in the back, and what appears to be a separate piece ramp sight attached in some way to the top of the barrel. One thing I noticed is that the front ramp sight appears to be slightly off-center relative to the grooves running down the top length of the barrel. Pending a range test to see if it is in fact off, I was curious if anyone has experience with these ramp sights and how they are attached, and whether they can be removed or adjusted.
A lesser question before I think about attempting it is whether the weight plug can be unscrewed (and if so, whether there is any reason to do so). I would send a picture but haven't figured out yet how to do so.
Separately, thanks for all the fantastic information on the Model 41, such as from TOMBECK, etc. This forum has been a great resource.
