Mak 90 Underfolder Flat

Out of stock

This is our MAK90 underfolder flat with top rails machined and mag well dimples. These come with lower bolt guide rails.

Due to the dimensional differences between these and the other flats you will need to use our Mak90 punch for the bending die.  Originally the receivers were made from .057" material and these are made from .050" annealed 4130.  If you have already bought the bending die from our website your user account should be activated to see the Chinese MAK90 punch for sale under the bending die category.

The internal dimension for the Chinese MAK90 receivers is 1.225" which is why a new punch will be needed. If you try to bend the MAK90 flat with the 1mm or 1.5mm punch it will not work correctly.

Currently we do not have the center supports that are narrow enough for these, but you can cut a 1mm center support down in length.

 This item is made in the United States and counts as a 922r compliant part.
