    What can go wrong if I saw off my Remington 870 barrel to a legal 18"?

    Why not just buy a spare 18" barrel?

    you can ruin your shotgun. the barrel can split if the muzzle isnt square. it can split if you cause a stress crack from sawing.

    as above just buy a 18" barrel.

    1. You do not quite get the barrel square
    2. You square it with a file
    3. Since it was not square, barrel is now 17.98 inches
    4. As measured by the guys over at the ATF lab.
    5. This is Bubba, your new roomate.
    6. Ignore the rumor that he killed and ate his last roomy.
    7. Well, not ALL of him, anyway. :eek:

    Seriously, never cut with a pipe cutter- crimps the barrel. Cut with a lathe or power hacksaw. Barrel steel harder than you think. After cutting, needs deburring and recrowning. Did you want front sight on there? Unless you have free access to pretty complete machine shop, and can use the tools, will likely be cheaper to get a second barrel already dolled up.

    Give my regards to Bubba.

    18.5".

    As long as you're confident that you are competent to do it.

    So I can't cut the barrel at an angle to make it look like the weapons on HALO or Unreal Tournament? Dang it.....

    Yes, you can- but just for you, we will make the cut at 180 degrees to the bore. That will allow us to remove the upper half of the barrel. It will make it much lighter, and easier to tell if it is loaded.

    What about porting it 3/4 of the way done the barrel to reduce muzzle velocity? But that wouldn't affect velocity down range.

    I'm disappointed in you C3. We both know that using a pipe cutter can cut and install the proper choke on the barrel at the same time...:D

    We actually had a case here in VA where a BG used a pipecutter to shorten a shotgun, used it to commit murder- we got a ballistics match on the Powrpiston- the plastic shotcup/wadding. Pipe cutter had crimped barrel, left burrs, burrs scored the plastic like rifling leaves marks on bullet.

    I agree it's better to buy a 18.5" barrel but if you're determined to cut it make SURE it's at least 18.5". That will ensure it's still over the legal limit of 18"-no matter how they measure it. I'm assuming you'll want to either reinstall the bead or put a set of sights on it.
