I’m probably showing my European bias but I’m still convinced US gun laws are a bad idea. For me, under a capitalist system (one that among other things, promotes an individualistic mindset and brutality in general), what they incentivise is accidents, suicides, school shootings, and random acts of violence. A large enough proletariat revolution would in my mind not require such gun rights; either a significant part of the armed force join you with their guns (unlikely) or the workers themselves can produce enough basic weapons (much more likely) to acquire more advanced ones from the former (a sten gun is easy enough to produce after all - it was meant to be easy to do so).

Moreover, acquiring an AR-15 slightly limited to EU laws in my country (which is possible through a “gun sporting license”, basically) would put me in a series of watchlists, with regular cops control; acquiring limited means of production (metal lathe, lead forge and the like) for simpler guns - such as a STEN ones - would not.
