I have one of the heavy duty cutoff disc for the Dremel tool so I think I'm going to shorten my barrel back 2". Should save me some money over going to the gunsmith.

While you are at it, add flutes.

If you angle the cut to resemble the AK slant brake, you won't need to worry about threading the barrel.

When I cut down my AK-104 and Krink SBRs, I just used a hacksaw...and a facing tool, a crowning tool, a drill, and some cutting oil.

For the amount of money you're going to spend to end up making it right, you should probably just get a new barrel at the desired length.

You should use a drill and a long bit to go up a caliber too, while we're improving and all.

Just be sure to keep it at NFA lengths.
And hopefully you have a good bit to re crown. Good luck, and post some pics

If you really want to save money, send it to www.adcofirearms.com They know what they are doing, they are fast, and do amazing work. If you are really going to use a dremel to cut your barrel, I predict a "bubba barrel" will be born! Even if you cut if straight, no way you are doing a uniform crown with a handheld dremel. Send it to adco! For the children! |

Use a tube cutter to mark the barrel where you want to cut it, then use a hacksaw. Finish the 'cut' by using a flat grinding stone to square off the end. Then you can crown it.
I helped a friend shorten a shotgun barrel from 26" down to 22" - then deburred it with diamond files - and it went well, a rifle barrel the crown is going to be the hardest part... I wouldn't want to use hand tools to do that, or your accuracy is going to go into the shitter. For that kinda stuff though, even a local machine shop could help cut it down and then square off the end. You can even get them to start a crown for you, then get a crowning kit to finish it off. |

No pipe or tubing cutters here and too lazy to go get one. Considered using a Sharpie to draw a line to follow but I think I'm good enough to free hand it.

I cut the barrel and grenade launcher thing off of an SKS once. Did the crown with a dremel and then some cold blue.
looked good, but I sold it before shooting it. It was my first rifle, so being a broke newb to guns it was proudly decked out in Ncstar and synthetic stock with the built in folder. A month later I saw a hood rat walking around with it at a gunshow. |

Barrels should always be cut back from the chamber end. Unless of course you're like 97% of AR hack owners.
It should be plenty tacticool, though. |

Apparently not. Shortening a barrel is not difficult at all. Re-crowning that barrel is a bit more difficult, but still possible with simple tools. Why all the anxiety? |

At very least find a hose clamp and clamp the barrel at the cut point. Then you have the clamp to guide a strait edge.

And according to a very detailed write-up in a precision shooting mag some time back, the crown plays much less on performance than traditionally given credit for. they intentionally beat the shit out of a crown by denting and cutting gouges in it with virtually no measurable decline in accuracy. |

Though some do seem to be better than others. It is not a tragedy when one flies apart, chicks dig facial scars, but you don't want a flying fragment to hit the eye. If you feel the need to look like Colonel Fury, just get an eyepatch. No need to actually lose the eye. |

Rig the barrel up to a hand drill to spin it while you cut. Should produce a square cut.
