Looking for Benelli M121 20” bbl

Hello everyone- I’m currently after a Benelli M1 121 20” bbl. Please drop me a note if you have one you’d consider selling- thanks!

Good luck. That's going to be a hard barrel to find, particularly in decent condition. I have a search on Gunbroker.com that notifies me whenever a used Benelli barrel shows up at auction. I also have a similar one on eBay. I probably have not seen 2 in 10 years go across the auction that I can remember. The 121's are not particularly expensive models, it might be time and money well spent to pick up a complete gun. on GB, I see them sell from ~$600 up and saw one in very good to near mint condition sell a while back go for $1,600 with accessories, and maybe the box, I can't remember. It was nice. I don't have any real desire for the 121 other than to complete my Benelli inertia shotgun collection, but I thought a while on buying that near mint one but ultimately passed when something on my list came up during its time.

Here's a search if you want to use for GB. It searches for Benelli M121 in shotgun barrels, and excluded M4, Shaw, slug, SBE and new barrels (since these aren't made new, but does include used and new old stock).

My 121 came damaged. USPS actually dented it near the muzzle. Dropped it off at my smiths this afternoon and he’s going to take 1/4” off and back face it as it’s a big dent. Not a huge deal but would like to track down another orig bbl one day.

If they haven't already worked on it, you might see if they can re-expand the dent back out. That's something akin to sticking a circle plug into the barrel, that then concentrically expands pushing the dent out. Sometimes heat needs to be applied if the dent is big like you described. Being at the end, it might make that process even easier. A barrel might be too tough for wood, but you might be able to take  a hardwood dowel that has the right diameter, but plane down the side so that it just fits inside. Then, slowly heat and rotate each way and see if the dent works itself out.

Here's a great video from Midway on their dent removal service:
