BullSh|t...
SAR21 need not to have a external deflector as the design already
consider that, the empty catrigdes will eject forward unlike the
M16 (to the rear) and Ultimax 100 (to the right).
I had demonstrate to the range conducting officer once that it is
safe to fire with left hand and its perfectly alright. Guess what?
I am not even a left handler... Even my guys (left handlers) find
it comfortable to fire with left hand.
SAR21 is design for both left and right hand firers, it is the
current right handler commanders have no confidence in it due to
their negative mental model/mindset, to play safe, they just
forbids people to fire it with left hand so that their arsh is
cover...
