Anybody know of anybody that works on AK's I screwed mine up bad trying to thread it for a krink flash suppressor. I need the screwed up portion cutoff and then threaded 1/2X28 so my Krink suppressor can be installed. Is that even legal.

I am not in Canada I don't know why my profile shows that. I am in Wisconsin (Damn close though). So I take it that what I have is not an original krink suppressor

When you say "Krink Suppressor", do you mean one of those Krink Flash Hiders that people are putting on their short barreled AR-15s?

Sorry yeah I meant krink flash suppressor. It's the one you can get from ADCO firearms for $110. I have seen them on AR's but this is for a 7.62.

Whoa whoa whoa...

First - what does screwed up mean? Did you try to thread & get the threads cockeyed? Run over the front of the gun with a tank? Let us know.... EVERYTHING that happens does not mean "cut off the end of my barrel" :)

I had to sand the barrel down to get it from.546 to .500 so I could use the die I bought. I threaded the first 9/16" of the barrel and the flash hider sits cockeyed. So now I spend my days punching myself in the balls for being so stupid I am a cop not a machinist. What the F^&* was I thinking. I have a picture but dont know how to get it on here.

OK - GOOD job. ALL IS NOT LOST.... I see that you said this:

"I threaded the first 9/16" of the barrel "

Now - is there a good chunk of barrel BEHIND that? If so, Good... you could recover from this.
The secret part that you are lacking is called a TAT (Thread Alighnment tool). You need one for a 7.62x39 barrel, designed for 1/2x28 threads. Use this, rethread (you can't really hurt the front part more), and go deeper. CAREFULLY screw your brake on to catch the "right" threads. Also - use an adjustable die to DEEPEN your new threads.

You can get one of these HERE:

Now - be aware of what success means. You can put a 1/2x28 flash hider on your 7.62 rifle - BUT YOU MUST BORE IT OUT! If you do not, and you try to fire a 7.62mm bullet thru a flash hider designed for a 223? DEATH OR SERIOUS INJURY could result.

No problem Dan :) For reference? I'm a Chemist. Eight years ago I knew NOTHING about AKs. Now? I have about 15-18 builds. We ALL make mistakes... keep at it - it's how we learn :)
