“...the jamming on a grain of sand issues...”
Again, that’s because of the design flaw of the M16/AR15 rifles - it craps where it eats. Very dirty design.
But it’s an OK weapon overall if you keep it clean. I like my AR and will keep it. But the Garand and the M14 hold a special place in me ol’ heart...
As well as Enfield No.4 MkIs and No. 5 Jungle Carbines, AK’s, SKS’s, lever-action Marlins and Winchesters...KAR98K’s, Springfield 03’s...etc.,
Even my old Mosin-Nagant M44 gives me a warm and fuzzy occassionally...
Great to be an American, ain’t it?
