For those that don't know, me included ( I had to look it up), the SIG716 in all of it's configurations is NOT an M16!
It is an AR-15 style semi-auto rifle that shoots 7.62 x 51 (NATO) ammo.
My rifle experience has been limited to .22 caliber bolt actions, a MN M-44, and , once, an M1 Garand in boot camp.
I still have the M-44 and a CZ452 (in 22lr). I qualified NRA Distinguished Expert with the CZ452.

If you aren't part of the solution, then you obviously weren't properly dissolved.
