M-1 Garand was the best rifle ever made, the M-14 was basically* a M-1 with a 20 round removable magazine.
*yes the M-1 was 30-06 and the M-14 was 7.62mm and could be made to fire full auto, but the basic design was the same.
BTW a M-14 on full auto fires at 760 RPM, so you will enpty a 20 rd mag in under 2 seconds, been there , done it ....hehehe
