It took me almost 3 hours last night to get my AK74 flat bent using this cheap *** jig. I had to take a rubber mallot and straighten the walls out of the flat! First off, the damn thing went through crooked and I had to back it off and readjust it! Next thing you know, the carriage bolts provided with this kit stretched and gave way. Not to mention, there wasn't a recess cut into the steel to keep the squared off area below the head secured in the steel plate. This caused the flat to literally "walk" while I was tightening the bolts in sequence! Sequence...yes that's a next one on the list, why is sequence left to right? Why not inside out? It appeared to straighten out better when when I tightened inside out the second go around after the adjustment! In the end i was hammering that got it close and level enough to actually call it a receiver. It's hard to tell how straight it really is though and I don't know if I should trust it as being perfect for the build. I am going to buy some grade 8 hex bolts, nuts and washers to reassemble the tool to see if I can bend a Krink flat tonight.
No pictures were taken last night as I was about ready to go ape s**t after the way the thing practically destroyed my flat!
