Mossberg 500 front bead sight mod

[jpwilly]

A few weeks ago I reported here about how my Mossy 500 18.5" smoothbore "security" barrel shot slugs 12-16" high at 50 yards. So I set about figuring out why. The simple answer is this barrel without the rifle sights wasn't intended to shoot them accurately in the first place. But that didn't sit well with me.

After some research and measurements I decided a 6mm airsoft BB would serve two purposes. Raise the front sight height and because it alsoglows in the dark I could actually see it at night. It was hollowed out to sit on the brass bead at the correct height then jbweld did the rest.



Here's the measurement between the barrel and the straight edge. The bead is only .155" the front sight should be arount .275" for shooting slugs at longer ranges.





The Results at 50 yards Holding with bead covering the orange circle (a 6 o-clock hold would most likely put these on the bull)

Creative, unconventional, will probably draw flak from someone, I love it!

^^ LOL yea if I hadn't done it myself I'd probably poopoo the idea too!

I cut the barrel of my Westernfield/Mossberg and havent yet put a bead or sight on it yet
I am really wondering if I shouldn't just take it to a Shop and get a big bead installed?
Right now if I center the top of the Barrel about at the bottom of the Bullseye I get hits at the top of the 8" bullseye @ 15 yards!
Obviouslly I need to do something to hit with it...

^^^ Yes or if you want to do some hillbilly gunsmithing you could easily to something similar to what I've done here. I had the advantage of being able to mount to an exsisting bead and if my experiment went south I could have fixed it for $3 for another bead or $10 for a fiber optic front sight.
