So I'm thinking about threading my barrel on my Sar-1. I want to run my aac sdn-6 on it, so that would mean 5/8x24 thread pitch. Must be concentric to the bore, obviously. So my question is:
Who can do this reliably? I'm not sending it anywhere that puts out a lame cya saying ya well thread your gun but don't use a suppressor. |

Quoted: Quoted: The SAR's had the muzzle threads turned down, so it's too thin to thread for 14mm, I did mine 1/2x28 and they came out fine. Maybe a few did but the vast majority were not. They were just not threaded. I have personally threaded four of them to 14mm LH. Well, I stand corrected. The ones that I had were too thin to thread for 14mm so I had to do them in 1/2x28, I had a SAR1 years ago and more recently a SAR2. That's why I love this site, I learn something new everyday. |

SAR 2 and SAR3 are thinner, |

Indeed we do. I love Arfcom. |
| Yep just buy an alignment tool, die and handle. The alignment tool will make sure the treads are concentric to the bore. Takes about 5 minutes. You will also need to install a detent pin and spring. Just tap out the front pin on the front sight, put in detent pin and spring, and tap the sight pin back in place. |

I'm just pulling this out of my ass, but I suspect threading a SAR, specifically in a manner that will guarantee concentric threads to the bore, will be cost prohibitive. it's around 100 bucks for the tooling to do it, less if you shop around a good bit. how exactly is that cost prohibitive? |

Well here's what I am thinking.
I found the aac mount I need on midway, it's a 762 caliber threaded in half by 28. Should be available withing 2 or 3 months. Now, I would like to have it debanned, so I could send it to a builder, have him pull the barrel. Send it down to be threaded by morgan at dss. Then have said builder install all the necessary parts and ensure everything is done correctly. Realistically will this be somewhat expensive? Perhaps. But- this is insurance against destroying my aac sdn-6 that I paid 1100 for, + the 200$ and 6 full months wait. Thoughts? Builder suggestions who are taking work right now? |

Quoted: And as I said before, my mistake, the one's that I've dealt with have been, so please excuse my ignorance.Quoted: The SAR's had the muzzle threads turned down, so it's too thin to thread for 14mm, I did mine 1/2x28 and they came out fine. That's odd, I have threaded about 6 SAR-1's that I have owned over the years and none of them were ever turned down.  |

Not worth all that trouble in my opinion. |

Screw it then? Sig 556R?  no, not screw it, just, you're overthinking/overengineering this. a TAT, or Thread Alignment Tool, is kind of a "starter thread" with a pilot that fits VERY snugly in the bore. it looks like this: 
And provides a concentric (to the bore) means of starting the threading die by hand, so that you don't have to pull the barrel--hell, you don't even have to pull the FSB if you don't want to--in order to thread the barrel. Get yourself a TAT, 14x1 die, and if you don't have a die handle you'll need one of those. should be well under 100 bucks, probably around 50-ish if you shop around. then all you need is a thread adapter and you'll be fine. the AK isn't the best platform to suppress, but you won't damage your stuff as long as you don't try to use a sledgehammer to thread it. It's a lot simpler than you're making it out to be.

I just threaded the barrel on my SAR-1 like a month ago at 14x1. I bought a threading kit off of the EE, and once it arrived had my barrel threaded in about 4-5 minutes. It was almost too easy. I didn't see the need to remove the barrel either, as I could thread far enough to tighten the muzzle device correctly.
Make sure you buy the spring and detent as well. |

You must mean the front sight? |
