I'd put these in the BIY forum, but it seems like this is the place to find the SMEs (Subject Matter Experts) on the Krinkov. I'm looking at doing a build, but I'm still researching my options. Perhaps you guys can help me along. 1) Is it possible to buy a Krinkov PISTOL, and attach a stock to it? I'm sure I'd have to remove the rear trunnion and replace it with a new one for the side-folder, or is there something in the pistol receiver which would make it excruciatingly difficult (if not impossible) to change a pistol receiver into a side-folder receiver? 2) I found a Krinkov kit (sorta) for about $370. Now don't get excited, it's a Yugo underfolder in 7.62x39 which has never been assembled. However this kit also says that the trunnions have not been drilled for pins, nor is there a gas port in the barrel (more drilling). I'm wondering if it would be possible to buy this kit and convert it to 5.45x39. I've thought about what this might entail and I wanted to see if the following is correct or if I'm missing something. If I attempted to do this, I'd need to acquire new: - Front & Rear trunnions (for the AK74 receiver i'd buy, since the kit is for an AK47 receiver) - 5.45x39 barrel Is that it, or would I have to consider the gas block and/or other parts? 3) If I decide to "Eh, screw it" and just build out the Yugo underfolder 7.62x39 kit, how difficult is it to mark and drill the correct size, and location of, holes in the trunnions and the barrel? Obviously the barrel would be the most difficult, but I'm certain that with my drill press and a lot of patience and caution a gas port could be easily drilled. Thanks to anyone who can help! _MaH |

ok here are my answers. . . not sure how correct some will be but i know others will chime in. 1) yes you can put a stock on a pistol after you finish your paper work, there is nothing in the reciever itself that keeps you from switching trunnions. 2)*** this is the one i am unsure about*** The trunnions may not need to be switched to be honest. I used a 47 rear trunnion to put a fixed stock on a 74 build. I am totaly unsure about the front trunnion though, but i have a feeling that it is also usable as long as the barrel has the correct rear diameter for that trunnion. I could be wrong due to the magazine lock up mechanism. 3)This is not hard with the drill press and some good bits. Go to Mcmaster carr and buy some good bits, like carbide steel ones, not just coated ones. They will cost you about 5 bux each max and will cut through the stuff no problems. I just had to do this on a build and its no big deal. They have a wide assortment of sizes so you can find one that is ALMOST perfect every time. If you need help finding what size bits and hole location let me know i can try to dig up some links for you. The only thing thats gona be hard to get is the gas port size honestly. That you may be able to get from calling some builders though. Hope that helps. Pat |
Thanks for your answers, but I'm actually not worried about the part in red. I found my answer to that already!
Granted, he's talking about using an AK74 barrel, modified to fit an AR upper, but if the gas port size for an AR15 blow-back system works, I'm confident it will work on an AK blow-back system. _MaH |

That may or may not work. It all depends on gas port size and location from the chamber. If he used a full sized 74 barrel on that build the gas port will be further forward i would think, and a smaller size. I honestly would call a few of the builders and ask, im sure they would help you with the info. It will save you headache in the end i would guess. Pat |
