AK Flat Bending Jig

The lower die will work with either the 1mm or 1.5mm flats, but it will take a separate punch for the 1mm or 1.5mm flats. These are for my newest flats that have the top rails already bent over and trimmed. The flat alignment is done using the trigger guard holes not the 1/8" holes. My next run of flats will be made without the 1/8" holes so it will be next to impossible to tell the difference between a factory made US receiver and one built in your garage.

This new design eliminates the flex of the welded together base which will give better dimension control of the width of the bent receiver. The other advatages are the radiused entrance into the die which makes it possible to bend the flats with less pressure. Springback control is also built-in with the new die set since we are not bending the top rail. When you bent the top rail on the old jig and used the step down with the supports the receivers would come out fairly square. Using the flats with the top rail already cut won't allow any springback control. So the answer to everybody's question of can we bend the new flat on the old jigs is yes and no. Yes you can bend it, but it will not come out as good as using the new die set. When you take into consideration the time saved by not trimming your top rails and how you can make a better receiver than before should be the goal of any builder.

All flats will have the step in the top rail as well as the angled cut on the rail behind the front trunnion.
