Got back from range testing today and put 100 rounds through it no problem. However when I got home and rechecked headspace it now closes on the no go. I know its because my barrel pin was drilled slightly off and I had a feeling this was going to happen. Kind of glad it did because its one more lesson in how to fix these situations and its a lesson in what not to do next time. I understand that I need to reheadspace and drill an oversized pin and repin. My question is where can I get an oversized barrel pin and what size drill bit matches. Furthermore I noticed the corner of the ejector got slightly mushroomed and worn to a slight 45. I heat treated everything properly and I am curious if this is abnormal. Any light on the subject would be appreciated. This is my first AK so I expected this kind of thing.

You can push the barrel out weld up the cut in the barrel re push it in then re drill it. Or you can use a over size reamer and barrel pin.

I'm with mrlonewolf 45 degrees on the ejector sounds weird. we need pics. As far as headspace goes you can drill for an oversized pin or you can get a field gauge and check it again. If you're not planning on reloading for this rifle then being slightly loose on the no-go might not be the worst thing in the world provided that it's safe.sigpicOriginally posted by Dr. ElkyOriginally posted by CSACANNONEERComment

Awesome thinking and congratulations for that approach builder.
1.- Press your BBL into the front trunnion as needed and obtain proper headspace.
2.- Drill and install oversize BBL pin.
3.- Retest your headspace after that.
4.- Be safe, be proud and enjoy your build.Would you like to participate in the Right to Keep and Bear Arms movement in California?

Thanks.. I already have it stripped and ready to headspace.
Here is the ejector pic. My casings were ejecting very positive and I did not have one ejection problem. I fit the ejector for bolt clearance prior to firing.
Should I press the old pin out or press the barrel back into proper headspace and drill it out when I do the oversize pin?Last edited by CIV Tactical; 07-17-2012, 7:45 AM.Comment

Yowza! That a serious ding. Deformation like that means your ejector was not properly heat treated. You'll need to dress down thew burr and fix the heat treat issue.
As far as the barrel pin. press it out, set headspace, then drill for the oversized pin.sigpicOriginally posted by Dr. ElkyOriginally posted by CSACANNONEERComment

Ok. Pressed the barrel pin out and repressed the barrel into proper headspace. My RSB was indexed perfect so it pressed right where it needed to be. I inspected the hole and sure enough I BOOGERED it. Now its ready for an oversized pin and I re heat treated the rails so hope fully another 15 20 minutes of careful drilling and it should be good to go. I inspected the ejector tip as well and There is still plenty of lip there to catch the extracting shell and eject it. Anyways thanks to everyone for you support. and I will keep you all postedComment
