LOL! I have to wonder how many of us here have
ever fired the M-14 on full auto. My buddy and I converted ours in RVN to full auto, but that was rare, few had access to the selectors to replace the fixed (whatever it was called) gizmo pinned in place on the majority of rifles. To say it was a bit uncontrollable on full auto is understatement. It could be controlled if you had one of the nifty M-15 bipods that screwed on at the gas piston, and fired prone. Of course, ya couldn't see squat from all the dust kicked up, but no matter, ya could keep the muzzle on target.
