| I have a sar-1 and am wanting to get the barrel threaded so that I can put on a brake. Is this a dumb idea or leave it alone? who can I send it to to to the work? and what brake should I use? Thanks in advance jm |

To do it by hand without a lathe and taking the barrel off, you'll need:
pin punches, threading alignment tool for a 7.62 bore, threaded M14x1L, and an M14x1L hand threading die. Die holder is optional, but recommended. You should be able to find everything on Brownell's and perhaps a few other general gunsmith supply sites. Edited for old guy brain fart on thread spec. 14 not 13. |

You'll need to remove the FSB to do it correctly as the threads will not be far enough down when you screw on the slant brake, leaving a gap between the rear of the slant brake and FSB if it's not removed... The "lead" for the die will not allow threading right up to the FSB. IIRC about 2-3 threads extend under the FSB. While the FSB is off you may want remove the GB as well and replace it with one that has the bayonet lug on it.
Some people built the bayonet lug back up by welding and then filing/grinding to the correct shape, in order to keep the original GB. |

Did mine, but was completely unable to get the front sight base off so I could put in the detent and spring. So I Locktited the brake on there and JB Welded the detent in place. |

I was thinking that all you had to do was drive out the front pin, install the spring and detent and replace the pin. I'm probably wrong because it seems like you need a press for just about everything with AKs. |
