Well, maybe you ought to experiment with the first cut at 22", that way you have a bit extra barrel left to make the "good" cut, or enough left for a gunsmith to do.
Pipe cutter will constrict the end of the barrel, though a pipe reamer should remove the resulting burr. Hacksaw TPI is going to depend on hardness of the barrel. Mask the area where the cut is being made (double wrap the tape) and be careful that the hacksaw doesn't "skate" and mark the good portion of the barrel. Clean up with file and emory paper and then cold blue. Never have done a barrel, but havedone similar items-not hard, but I am very mechanically inclined with all types of tools. I must add, and not saying it to be a smart azz, but if you have to ask how fine of hacksaw teeth to use, you just may want to let someone with more experience help you out. |

Never use a pipe cutter. It WILL constrict the bore.
That said, use a fine tooth hacksaw blade. Cut at the attaching point of the rib closest to your desired length. Straighten cut with a fine cut mill bastard file. You can smooth the cut by placing 400 grit wet/dry automotive sandpaper on a board and standin the muzzle on it. Holt the barrel as straight as you can and twist it to sand the muzzle. Chamfer the muzzle with a sharp pocket knife. Touch up bluing as necessary. |

You have gotten a lot of advice!
If you have the option,and if you are using a hacksaw,its true about any of them will do the job. If you want top quality,Simonds or Starret make nice blades.A bimetal blade has a high speed steel edge with a spring steel back. Actually a quality hacksaw frame makes a difference.Just look close for rigidity and quality .Look at the tensioners. On the pitch (tooth count) :You don't want your workpiece to drop into the tooth gullets.Ideal is at least 3teeth in contact with the work.If you can find a 32 tooth,great.28,probably fine.I wouldn't go much coarser.Use a little WD-40,focus n long,straight strokes.No pressure on the back stroke. You want your barrel held rigid.But,your typical vise offers problems.Crushing it in a vise,obviously not so good.The barrel is tapered,one end will drop.Blocking it up might work,but, If you have access to a table saw,make a 2x4 ...maybe 10 in long,into a vee block. Then you can secure the barrel and vee block to the bench with a couple of C-clamps There are other ways,of course. Not everyone has an adjustable die maker'ssquare....but suppose your square has a 4 inch stock.How much is your barrel taper per side over 3 1/2 inches? That extra 1/2 inch is the width of the feeler gage you can shim your square with.Check from both sides.A uniform chamfer with a fine half rounf jeweler file can be close for a chamfer.Something like a 1 in round mounted grindstone can be turned in your bare hnd for a chamfer. Another thing you might check.I never owned a Mossberg,I don't kmow for sure,but seems like some of their barrels are "back bored".As I understand it,rather than a forcing cone tapering down to traditional bore dia,it does not taper down.The wads obturate to pretty much chamber dia till you get to the choke. For cheap,that means drawn over mandrel tubing You cut the chokes off a back bored barrel it might not work right. And there might be some kind of pattern science in venting off the gas so it doesn't scatter the pattern.Its OK to not like a vented barrel,but they might be about blowing the head off a turkey or something. Before you cut,study that rib real close as far as how its attached.Oneway was little dovetails and the rib would just float in those.It was soldered on at the endsThe rib had a sort of lug for the solder joint.You cut that off and you lose your anchor. Thatswhere talking to your smith might be good,ahead of time. Fitting a"dutchman" and getting the torch out with some Hi-Force 44 might be in order.....And sometimes a shotgun barrel does really weird things when you warm them up! I do think letting the smith do it is not a bad idea,especially if you have to buy tools. Last edited by HiBC; July 11, 2017 at 06:34 AM. |

The above post has been most helpful in making me think it isn't as simple as cutting and straightening the cut.
Is it accurate to say the barrel is design in a way that cutting it will not result in a simple cut but will screw everything up about the barrel and accuracy? |

I emailed rose action sport and never received a response on the cut job.
I am increasingly thinking this isn't difficult at all given I am not threading for chokes. I think it's 75% going to happen in the next week or so. I've read on many forums that Brownells sells a cheap drill and tap set for attaching a new front sight bead. I haven't located it though. Anyone know where it is or an alternative cheap set? Other option is the drill and press fit bead. |

Or just leave the bead off entirely - that way there is no OOPS, it's off center moment....

Yeah. I mean, I can try contacting again...but the cost will likely be at or over $70. At that point I should sell the 28" and put the 70 towards the stock 20" Vent Rib choke barrel.
It's amazing that Mossberg's replacement barrels go for the new cost of the same brand's Maverick 88 shotguns...which come with the same 18.5 or 28" barrel |

Tooth count matters.
A 32 teeth per inch blade will cut much smoother than a 24 teeth per inch blade when it comes to hack saw blades. To keep it square, band clamps. You can run it around the rib and barrel or slip it under the rib, using it as a guide for your cut. I agree with having a smith do it as it's not typically a terribly expensive endeavor. However, the tinkerer in me understands and appreciates, doing it for my own self. I've cut a couple of rifle barrels down and re-crowned them with very good results, but they were stainless and bluing was not an issue. I don't see a shotgun barrel being a terribly difficult challenge. That is unless the rib is not actually attached to the barrel where you intend to cut it. If that is the case, I believe that I might attempt to install a bead that could bind them prior to cutting. Take your time and have fun, learning as you go.. but that's just my opinion.

Thanks!
I guess if I cut the ribbing and remove some of it towards the muzzle, the band could fit and act has stop for the blade. On bluing, which I've never done, I will throw away length to practice on. But what can I expect regarding matching the stock black? Thanks! It's happening Will post pics, unless everyone was right to have it done professionally. |

You could attach the clamp on the section of barrel that you're removing and cut behind it.
I've tinkered with bluing and matching a factory blue job is typically not an option, but you can get close enough. For what you're doing with it just being mainly the cut, I would choose a gel or paste over a liquid. One that you could apply exactly and only where you need it easily. Cut a bit longer than what you're thinking if the rib will allow you to. That way if you're not happy with the results or you experience a learning curve, you've got length for yourself or a smith to play with.

Good advice. Thank you for the bluing information.
Maybe I'll try cutting close to the muzzle as a practice run. |

Back in the day CDNN was selling Saiga-12s for $199 each, this was right when the Federal AWB expired via sunset in Sep 2004. I bought 2 in Aug of that year and then the day after the ban expired converted both of them to a regular AK pistol grip configuration..........part of which required cutting the barrels down to 18", I think originally they were 22' or 24". Over the next 6 months I did another 6 conversions. I did all the cuts with a pipe cutter from Lowes dressing the cuts with a dremmel or file. Never had any problems or issues.

Could someone look on homedepot.com and post the link of what file should be used to straighten the hacksaw blade? Just picked up the Dewalt 32-TPI blade.
I've used a deburrer before, but I don't know the differences between files. Thank you! |

Besides, in the OP's case, his barrel has a rib on it.

If you do cut make sure to deburr the inside otherwise it will cut patches when cleaning.

Perhaps you made a mistake in your post.
You don't want to file the hacksaw blade-you want to file the muzzle. You want a fine-cut mill bastard file. You can easily deburr the inside of the cut with a sharp pocket knife. |

And, worse comes to worse, if you screw it up, a new barrel isn't that expensive to replace.... (although I still opt for the smith performing the work)

Haha, no. I didn't mean I was going to file the hacksaw
Still...anyone recommend what/kind of file? Any of these? http://www.homedepot.com/s/bastard%2520file?NCNI-5 |

Ah. "Bastard" removes the most material. The HD guide helped.
Should I pick up a bastard and another one to clean? Second or smooth? Not sure what to expect the file will do to gun barrel steel. |

You might be overthinking it a bit.
Try to get a fairly fine flat file that is wide enough to cove the muzzle. There is no magic tool.Its what you do with it. |

Agreed. There are just 3 levels of a file. You said fine and someone else said the coarsest.
No not about filing metal |
