A cursory glance by this goober thinks this looks similar to the FN P90…
I think it is. The AR57 is somewhere in there too, as well as an illustration for a revolver looking pistol that used a shorter P90 style magazine.
yep thats my gun, patent looks just like it
Oddly, there isn’t one that I could see for the gun itself.
Interesting gap in the timeline…
2009-01-31 Anticipated expiration
2019-08-15 Application status is Expired - Lifetime
I thought patents were for 25 years? Looking thru many of the things there. It seems more like 20.
From our Patent class, 20 years if you keep up on it.
