AK flat

[TATER313]

Has anyone had any issues with ak builder flats, I have bent many before without issue. Using the ak builder flat bending jig all pins were lined up and tight onto the punch. but after bending it, it is 3-4 mm higher on the left front side, making the front trunnion to canted. when taking it off the punch the pins were still lined up correctly. is it just a bad flat?

Never had that issue or seen an issue at the BPs I have attended. If it did not shift in the bending jig and the jig is not bent/broken and when pressed it went all the way down into the jig it must of been a bad flat.
Does the reciever sit flat on the bottom when placed on something level and flat? If it does and is not twisted... Is the mag well centered on the bottom of the receiver?

There was an issue on some ak75 flats but the difference was .020" so we just shifted the flat on the jig aligned it by hand and calipers and pressed it that way.

Yes It is flat at the bottom and perfect by the rear trunnion. I have bent many flats and had no issues. I will pick up a new flat today and start over.

I have an underfolder flat that came out that way. But it was a couple years ago that it happened.

I just did a HD 1.5mm AKM flat that came out like that. Not as bad as yours, but one side is higher than the other and the trunnions are canted

Happened to me once. The flat jumped out of the pin that holds it in the single trigger guard.

There was no way it jump pins bottom plate was nice and tight, and pins were in mag well and trigger guard after flat was bent. the mag well is slightly off centered. Bad flat. bent 2 more flats after no issue.

That was because someone didn't tighten down the plate

It happens. Something on the CNC punch press hits the flat as it's being punched shifts the whole thing off center a touch and now when it bent referenced off of the off center holes it's all screwed up
