What tool do I need to shorten my shotguns barrel

[BoomBoom25]

I just received my dads Remington 870 pump shotgun with a 26 in barrel. Well as much as I love the gun as is I already have Maverick with a 28in barrel that I love bird Hunting with. What Ive been wonting is a nice short barreled shotgun I could Use as mu home defensive shotgun. I was going to buy one until my dad up abd gives me his shotgun. He has bad arthritus and doesnt hunt much anymore. Anyway I decided I wonted to take on this project myself and save a little money. Now I already know the barrel cant be any shorter that 18.5 in barrel. I have spent some money on this project like I bought a new black synthetic forearm and collapsible stock. I thought i could save a little maney and have a little fun by shortening the barrel myself. IM just not to sure what all ill need to do the job right. Also after ive shortened how do i put a bead sight back on what tool do i need for that? Could somebody please help tell me how to do this right? i would greatly appreaciate it.​

http://www.cabelas.com search " MOSSBERG BARRELS" . Cabelas sells Mossberg manufactured 18 1/2 in. barrels for the Remington 870 for $99.99. I have 2 on different 870's and they work just fine. As for shortening your present 26 in barrel which is worth more than $99.99, it can be done with a hacksaw then filed to repair the bad cut of the saw, you can use a pipe cutter then file to smooth things out,then reblue or cold blue. But the hardest part is putting a front sight on in the right place.

I'm with Bear don't cut it. Buy a new barrel. It is safer and easier. The plus is if you ever sell it the additional barrel will help raise the price. Cabela's and Brownell's should be able to help.

Those long barrels are to sacred to be hacked up. As you should realize now, you can get replacement barrels that already have the crappy factory sites on them already. And if you decide to do serious shooting, hunting of anykind, you will need that 26 inch barrel unless you buy yourself one of those cantilevered rifle barrels for your 870.

I know for a fact that the 18 inch IMP CYL 870 barrels are only meant for close in buck shot work. i spent good money on several scope bases for my old 870 before I realized it just had no constant accuracy with hunting ammo.

If it doesn't have a rib, a pipe cutter will do it. Then you'll have to carefully file off the burr. For the sight, you'll have to drill and tap the hole for the bead using a drill press, Vee blocks and the correct drill and tap. Getting the bead absolutely top dead centre isn't difficult if you have an eye for it. Otherwise, have a smithy do it.
Having said all that, my barrel split at the muzzle during a plate shoot. I'm very glad I noticed it before I shot again.
Pitch the folding stock and go buy a barrel.

If you insist on cutting it down....................

Here's my patented non-gunsmith home barrel cut down instructions:

To measure the barrel, put a cleaning rod or wooden dowel down the barrel with the gun's action CLOSED.
Mark the rod even with the muzzle.
Remove the rod and measure from the end to the mark. That's the actual barrel length.
To determine where to cut the barrel, measure from the end to NO LESS than 18 1/2" from the end.
Lay the rod along side the barrel with the first mark even with the muzzle, and mark the 18 1/2" mark on the barrel.

Measure the barrel to locate the cut off line.
Measure the barrel again.
Have a friend measure the barrel.
Measure it yourself one more time.
(Mistakes are not correctable, or forgiven by the BATF).

Wrap a piece of tape around the barrel at the cut line to use as a cutting guide.
Use a high-tension hacksaw frame with a new fine toothed blade.
Make a shallow two or three stroke cut in the barrel. (Make SURE you're cutting on the right side of the tape. See above about BATF).

After making a shallow cut, rotate the barrel and make another shallow cut, continuing to make shallow cuts and rotating the barrel until there's a shallow line all the way around the barrel.

Then just continue the process of making a couple of strokes and rotating the barrel until the barrel is cut through.

Lightly file the muzzle to remove cutting marks, then wrap some fine metal-type sand cloth over your thumb and use that to break the sharp inner muzzle edges.
Use a fine-cut file to remove the sharp outer edges of the muzzle, and touch up with cold blue.

The tape and shallow cut method prevents the saw cut from "drifting" and leaving an angled cut. This prevents having to try to square up the muzzle with files, since if you're careful, this will produce an almost perfectly square cut.

If you'd like a front bead, Brownell's sell a Remington-type bead on a small base that can be attached with soft solder or possibly the new Loctite Black Max adhesive. This too can be done at home.
