M4 Carbine Range question

[troopie]

Question for those questioning accuracy or range. When the weapon is tested, is it being held at waist level, shoulder level or balanced on a bipod. In my 40 plus year old experience an R-1 [the South African version of the FN-FAL] was much more accurate when fired on semi-auto than on full auto, and much much more accurate when fired on a bipod. Also, the effective range was about 450 metres from waist level, 500 from shoulder level, and 550 metres from a bipod. But that is just one rifleman's experience. What do others say.

IMHO, leave the ranges as they are.
