Cutting down a barrel
#1
i have decided that it is time to have a few shotguns at the ready around the house. I already have a mossberg cruiser and a second to come home soon.

I also have a few others to chose from if need be.

But the jist of this thread is about cutting a barrel down to the prescribed 18.5 inches allowed by law.

I have a Remington 870 action express in 20 gauge I wish to set up for the wife. Sure she can handle the 12 gauge, but why not set one up that would be easier her to shoot.

The barrel in question has a vent rib on it. The plan is to cut it down where the rib attaches to the barrel. Am I correct in the assumption that each spot that touches the barrel is welded in place?

I also have a Winchester 1500 that might be a better option. No vent rib and it is semi auto.

The vent less barrel would be easier to turn down on a lathe, but the vented barrel can be done. Unless they changed the minimum barrel length, I cut min down to 18 1/8". Just make sure it complies or you will have to get a tax stamp

Thanks. That is why I will cut it at 18.5 just to be sure. I was not planing on useing a lathe. Just a hack saw or a portaband.

I did mine with a verticle bandsaw. It turned out fine, just needed a little touch up with sandpaper. A hacksaw would be a little more difficult to get right.

I think the portaband wound work well. Take a practice cut first.

for that matter there is a chop saw at work.

Keep in mind that the atf measures from the muzzle to the closed bolt face.

Use a band saw before using a chop saw. If theres a cold saw that would be better

So, close the bolt and drop a stick down the barrel? Serious question, I'm curious.

Yep, Thats how its done. Find out your over all length. Subtract 18.5 from it. That would be the amount you can cut off.
Stick a dowel down the bore with the bolt closed. Mark the stick at the end of barrel. Measure the dowel Say the current barrel is 26" and you want 18.5". You would cut off 7.5"

26-18.5=7.5
overall 26"
Disired length 18.5"
amount to cutoff 7.5"
