I am absolutely no help, but: contact Weatherby at Customer Service 307.675.7840 and see if they manufacture such an item.

Check on gun broker dot com and see if anyone is selling one.

Check ebay for the same items.

If all else fails you can buy, for about $120, a 26 inch barrel and cut it down to 18.5.

I use a plumbers pipe cutter on shotgun barrels - they are not hard steel and it makes a nice smooth cut.

Good luck and WELCOME to SGW

 

Just have that barrel cut down. You can always buy a regular barrel later.

 

Cutting down semi auto barrel may make gun not function properly as the amount of gas to cycle the action will be reduced

Cutting down the barrel will work as well as a short barrel, but your point is well taken.

If it were cut too close to the gas ring maybe, but anything 18" (minimum legal) or more will function fine.

 

Have you found a shorter barrel? Im looking for a 26 or 28 inch barrel for my 20 gauge SA-08. If you have one to sell, please let me know.

 

You'll likely better of buying the whole gun: https://www.gunbroker.com/item/1069365818
