How To Build the Suomi M-31.
This CD based book covers my building the Suomi sub-machine gun from a demilled parts kit through a functioning, legal semi-automatic 9mm carbine fully approved by the BATF.
This documentary "How To" type book offers ideas and insights as well as specific information on my build process.
This CD has been reviewed by the BATF and the gun itself is fully approved! The BATF approval letter is included on the CD. To the best of my knowledge, this was the very first BATF approved Suomi M-31 design.
This indespensable book is available for only $27.00 (including shipping) , directly from me. Please see the "How To Order" menu button to the left.
