Tiny,
The DDM4 is a version of the M4.
The M4 is a variant of the M16A2.
(go to the DDM4 specifications page)
The M16A2 is based on the AR15 platform.
The AR15s design is Stoner's.
Stoner developed the NATO 5.56 specifically for his assault rifle.
End of story.
...
PS. You have to specify if you asking about the ARmalite Rifle that became the c601 then Designated the M16 or the Colt Ar 15 with a different seat, trigger assembly, selector switch and barrel twist.
Two different weapons....
For as long as we’ve been a nation?
Go ahead.
Just bcuz black folk got better at violence than white folk does not mean y’all are never violent.
White folk burned down cities before black folk ever did. ...
