Did you honestly just say that there is no reason for “M4 type assault rifles”? Do some time in the forces and you’ll figure it out pretty soon, kid

There are some reasons for military use of M4 assault rifles. Unfortunately, as long as we have armies, they need ‘good’ (as in: of good quality, suited for the job, etc.) equipment,  I get that. 

But there are basically no reasons for civilian assault rifles.
