While out on an HK45c scouting party today, I ran across a very nice old Wingmaster for 175. I couldn't say no at that price, so I brought it home. Only Problem is the barrel has been cut down to 18 inches, so I am going to make a HD shotgun. Whoever cut down the barrel neglected to add any sights. There isn't even a bead. I've been researching this afternoon, and it seems the xs banded ghost ring sight will work. Are there any other options for a bare barrel? Also, how imPortant is a rear sight on a shotgun? None of my hunting guns have rear sights,'and I manage to knock down birds just fine.
