Thanks for your input, I have heard that Swissicon rifles in general are particularly accurate, but the IG11, which as you have said has a longer sight radius and barrel, is more so. Due to the weight the recoil is not very severe either.

Unfortunately, there was no troop tag under the barrel. However, I have come to learn that the "P25" marked on the barrel means that the previous owner bought the rifle out of Swiss service in 1925.

Now that you mentioned it, I may go looking for a bayonet for this rifle. The common variety seem to be available, but the 1914 pioneer bayonet would be quite impressive on this unit.
