I echo what ACC and flightsimme said, buy a new 18½" Moss 500 barrel or just cut it yourself. Buying a barrel will give you a pre-installed front sight. If you do DIY cut it, then buying or borrowing a facing cutter will make it look pretty. Good luck & stay safe!I have an old 12 ga plain barrel for my Mossburg500/Maverick 88 that I would like to have cut down from 28" to 18 1/2 " so that I can use it on my HD shotgun. Can anyone in the Indpls area help me out with this? Glad to pay you for your efforts.
If you do this, BE SURE that you are using a METAL BLADE and your cut in on the outside, (muzzle end) of your 18 1/2" mark. When you are done there will be burs around where you cut. Any metal object larger than the 12 gauge bore will work fine to de-bur the rough metal both on the inside and outer edge of the cut. Then be sure to smoothen all areas of the cut, run a piece of cloth through your barrel from the breach to the muzzle to clear any metal dust or shards. THAT will cost you, $.00I'd saved this thread for a 30 inch barrel but haven't addressed it yet.

I don't know what I don't know. I was just planning on using my Ryobi miter saw with a fine metal blade and chopping...www.indianagunowners.com
