I think the SAR-21 GL and M203 is both unbalanced. Bcos the
SAR-21 is designed with a built in laser at the front to balance
out the weight at the back due to bull-pup designs.
The problem with the SAR-21 GL and perhaps the SAR-21, is that the
design of the hand guard and pistol grip is too bulbous, aka too
fat and around to hold properly. I wonder too, if the iron sight of
the weapon have been remedied anot?
