After my ugly experience with Classic Arms (http://www.sksboards.com/smf/index.php?topic=79273.0
) was close enough to wrapped up, I started digging around locally for nice M59/66s. After a couple hours of calling, I got a call back from a small shop, said he had one I had to see, and he'd put it on hold for me. Couldn't drive fast enough!
It's not perfect, but it was good enough for me and MILES better than the one Classic sent me, so I wrapped her up and drove her home. Cosmoline was heavy, but really, aren't they all? After I got everything clean and lightly oiled, it was pretty clear the handguard wasn't teak like the stock: as the cosmo came out of the wood, the stock got several shades lighter, and the handguard didn't. I'm not really crushed over this, but it is a negative. I've got another stock set on the way that I plan to do up all nice, and keep the originals un-molested and C&R friendly.
The one thing that did give me real trouble was getting the firing pin retaining pin out: I did my homework, made a jig out of wood, and then landed some clean blows with a punch, and eventually drifted it out. Everything cleaned up nicely, and I made double sure to get the firing pin channel clean as a whistle and lightly oiled. I reassembled everything, grabbed some standard Russian 7.62x39 poly, and headed to the range.
[I didn't know it at the time, but I think I did the damage that very first time I put the firing pin retaining pin back in. I didn't notice any resistance.]
I only fired about 10 rounds before calling it quits, and I'm glad I did, and I think I got stupid lucky here. The AK front sight adjustment tool I brought with me wouldn't fit over the front sight post, and my shots were too high and flirting with the automatic target system. I did notice one insufficient primer strike, although it went off and cycled fine on the second try.
By the time I got home, the firing pin was completely stuck in the rearward position. I was NOT thrilled. The first thing I did was saturate the bolt in Hoppe's gun oil, and let it penetrate the channel. Still frozen. I drove the firing pin retaining pin (Getting easier now!) out, still no movement. At a loss, I put the punch from the cleaning kit on the firing pin face and gave it a gentle tap. I got about 5mm movement off the love tap, so I drove it out (gently!) as far as the punch allowed. When the hump popped out of the channel, I saw what was wrong.[No longer visible is what looked like the sheared-off metal from that hump: it was sitting on TOP of the hump, restricting the movement. It fell off after the pin finally went through the second part of the bolt.]
I THINK what happened was, when I was reassembling the bolt for the first time, the firing pin walked rearward as I was hammering the retaining pin back into the bolt, and the pin dug through the hump on the firing pin on it's downward charge.
I'M CONFUSED why I got such a great 'CLICK' as I flicked by wrist right after I reassembled, though. When I got home, it was FROZEN. I shot no more than 10 rounds and the last shot seemed to cycle just fine! Again, ammo was standard Russian Poly, non-corrosive.
Have any of you seen this before?
Is this firing pin unsafe?
Any thoughts would be appreciated!
