Well i think the made it like that so it's cheaper in the long run to maintain the spares and production. In terms of issuing the other parts i believe it will be a case by case baseOriginally posted by storywolf:Surprise to see sure strong recoil from xm8.
The US seem to flavor it as it can have part taken out and switch to configurate it - from a full rifle to sub-machine gun, carbine .....etc to suit the situation. Well not too good as you are issue with more parts to look after, maybe the US think that their soldiers alway after one mission can go back to camp sort out the parts and change. In other countries we don't have that luxury.
Also change configuration will soon or later make things loose and affect the aiming and zeroing !
