Protobable - This gun is a little bit of a misnomer.  The name, and even it's barrel length implies that this model has long range.  But the truth of the matter is that it suufered the same as all the 62 caliber paintguns.  The paintball just didn't retain enough energy to be effective at long range.  It was probably best suited to the short range ambush, but the longer barrel probably would be a hinderance in that capacity.
