Kulsprutepistol m/45 designed 1944/1945, manufactured 1945 – 1964 in Carl Gustafs Stads Gevärsfaktori, Eskilstuna, Sweden, 1965 – 1970 licensed to Maadi Factories, Egypt, and a random day 2024, Jim Fuller and some random Home Depot in Scottsdale AZ. Yep, this Swedish K’s receiver was a Home Depot fence post.

Fun facts:

It is a full auto only weapon with no semi option, fired from an open bolt position
This was the standard SMG for the Swedish army from 1945 to 1965.
In April 2007, the Swedish K was officially declared obsolete and was retired from its final user, the Swedish National Security Forces
Due to its simplistic design, there are plenty of unlicensed copies out in the wild
