HK33/93 receiver flats have arrived!
The finest stamping ever available for the HK33/93. Can also be used for HK53 & HK53K builds with a little extra work.
We hired a master tool and die maker to adapt our German HK G3 stamping dies for use on this 33 flat. HK Stamping tools are like jig-saw puzzles. You put the die-sections in that you need for each particular receiver being made. Many of the pieces are used for multiple receivers
Sourcing the material was the hardest part. 33 flats are thinner than G3 flats and finding the correct metric steel in the USA was impossible for the last couple years. We were not willing to sacrifice quality or strength, so we waited....but the wait is over.
