Key Points – The M14 rifle, adopted in 1957 to replace the M1 Garand and BAR, faced significant criticism from US infantry despite aiming to provide more firepower with its 20-round box magazine.

Firing the full-sized 7.62x51mm NATO round, the robust-looking M14 could pack a punch and was accurate out to 500 to 800 yards, depending on what kind of optics the rifle was fitted with.
