Quote HistoryOriginally Posted By KDG_Dave: That was the other thing that bugged me besides the selector marking. My rear trunnion is actually set in a little crooked. The gas tubes are ok of they are a little on the loose side as that will very even with Bulgarian guns. Mine has about the same as my SAM7K. When I 1st broke mine down I had to pry my gas tube out and change the angle of the rear portion of it so that it can be removed and installed how its supposed to be. As my 1st PSA, and hearing all of the horror story's about them I took a chance on it anyway pretty much knowing it was going to have something weird about it. Shoots good but I do have some concern if they even dimpled when setting the trunnions. My money is on no. Fun gun to shoot and functions great so far, but clearly basic QC is still not there forte still lol! https://i.imgur.com/wgeAD1o.jpg Quote HistoryOriginally Posted By KDG_Dave: Originally Posted By mak0: Two little things I noticed taking down my krink for its first cleaning: 1. the rear trunion is not flush with the back of the receiver. Looking closely at some pictures of other PSA krinks it seems like they're all like this? Kinda strange but is really just a cosmetic thing in the end 2. the gas tube has some play. I know this is not uncommon for krinks but it seemed to be more pronounced on my PSA compared to a friend's Bulgarian krink. Other than those two nitpicks the gun has been running great for me.

Quote HistoryOriginally Posted By mak0: Oh wow, that is much worse fit than mine I can pretty much guarantee they didn't dimple the trunnions. Only a matter of time before these things start seeing loose trunnions especially when PSA can't even set a trunnion right. |

Quote HistoryOriginally Posted By Stepbruhsolja: Is a brace available that utilizes the folding trunnion mechanism?? You can use any brace that attaches to the pic rail. The way PSA does it across their AK line is essentially a double folder....you have the rear trunnion that folds and you also have a pic rail adaptor that folds. That way you can SBR it. |

It looks like a lot of things might be misaligned. The dust cover fit looks a bit off and so does the recoil spring button. Maybe it’s just the angle of the pic but I don’t think the recoil button thing on mine sticks out that far. I’d have to go check to confirm 100% though. I will go look and snap a pic shortly |

I've seen some recent PSA Krinks (serial numbers around 15xx) and the trunnions appear to be fit properly/flush now. I wonder if PSA will correct a poorly fitted trunnion under warranty. Clearly they recognized an issue and corrected it in production.

Got my krink out again with some changes from initial range report when new
Went with a RS Regulate mount and a PA micro prism over the poor iron sights that are hard to see. Also used IMI 55 grain 5.56 as baseline. Zeroed at 50 yards. 5 shot group just over 1 inch which i am very happy with. No failures at all. Was popping 6-8 " steel at 100 and 125 yards no problem. Will try some 77 grain otm to see how it performs,but so far it loves the IMI 55 grain. Action seems to be getting smoother now with more rounds through it Love this krink more and more. |

Anyone else see this? Edit: This is actually from a brand new PSA 104 after 500 rounds. Keep an eye out on your trunnions though because the same 4.5 trunnion is used in our KRINK's.

I can promises you none fit the rear trunnions without forcing them on the KRINK. I don't care how many have sold they are not built anywhere near the quality of a good import and there AK sales are no match for how many proven imports are out there. Trunnions don't do this when they are made out of hammer forged steel...especially at only 500 rounds. They are thrown together without a care in the world for putting out quality and you can clearly see it right when you open the box up. Its an embarrassment right down to the over beveled extractors. |

You have the crooked trunnion. So have you sent it back to PSA? Personally I have fired 4 krinks, none have issues with stocks. This was the first, which has a slightly different set up.   |

That was one PSA had at The Gathering that went through about 5k rounds in 2 days. Just to be clear...are you saying Toolcraft doesn't hammer forged the trunnions? Also, you realize PSA does the trunnions to fit their own stocks, and that other stocks, even if the same mm, may require fitting (just like a plethora of gun companies advertise about their own products and after market stuff)? As I read your posts it sounds like you want PSA to make a universal fit which we both know doesn't happen, especially in the AK world. |

Quote HistoryOriginally Posted By d16man: That's not my gun. That was one PSA had at The Gathering that went through about 5k rounds in 2 days. Just to be clear...are you saying Toolcraft doesn't hammer forged the trunnions? Also, you realize PSA does the trunnions to fit their own stocks, and that other stocks, even if the same mm, may require fitting (just like a plethora of gun companies advertise about their own products and after market stuff)? As I read your posts it sounds like you want PSA to make a universal fit which we both know doesn't happen, especially in the AK world. There is no way that is a hammer forged trunnion. Hammer forged trunnions don't crack like that. Its cast. Front trunnion is hammer forged. the rears are not. The AK market is flooded with aftermarket stocks and braces. It would be really stupid on PSA's part to have cast 4.5" trunnions made proprietary only to there own stocks. They know damn well people will want to use all types of different ones. I mean if it was done on purpose why even use a 4.5 pin set up??? You can keep on trying to justify there poor quality if you want to. The ONLY fitting I have ever had to do on a triangle folder is just file a tiny bit off the catch slot. I have never had to remove material of the hinge section of a trunnion or stock on any AK builds I have done.

Quote HistoryOriginally Posted By FlyLeaf: Forgot to check mine for cracks. I'll check it later today. There are a few on youtube with several thousand rounds on them with no failures. Time will tell I suppose Check that rear left rivot to to make sure there is no cracks on the receiver itself too. |

Checked mine pretty good. No cracks or stress marks on trunnion or rivets. I only have 150 rounds through mine. Will keep an eye on it,but so far so good. |

Quote HistoryOriginally Posted By KDG_Dave: Trunnions don't do this when they are made out of hammer forged steel...especially at only 500 rounds. I'm assuming you're referencing the rear trunnion since that's what's showing as being broken. But rear trunnions are not hammer forged even on Russian rifles either. |

I think it is Vid 3 where they show Toolcraft and where they make the trunnions. Hammer forged certainly can crack. I am not aware of PSA using any cast trunnions. I might be wrong though. @palmettostatearmory Josiah can tell us all. As for the pins... AR Mlok slots are all supposed to be the same. I have had to alter things before. Same with QD cups. Same with barrels and gas blocks. Tolerance stacking is a real thing. I know you want perfect with absolutely everything, but you know that ain't achievable. What I can say is PSA manufacturers stuff to PSA specs. |
