I have hw100k, and it feels lighter than the factor, the factor isnt an ergonomic gun, nor is it light, its quite a long gun and quite front heavy which isnt a trait i like, but i've stuck my day/night vision on it and use a bipod, according to hatsan instructions both rc and standard weigh 7.9 lbs, the rc has a large regulator unit on it and the carbon tank, so rc doesnt appear lighter than standard version, by the time you fit mounts and a scope you could be up to a 9.5 lb gun, not light, a AA s200 weighs 6.6 lbs, a artemis p15 about 4.5 lbs, so if weight is a problem i'd think again, or try at an rfd, i'm keeping mine as i can fill the two mags and fire 42 shots and its still got the new gun aspect. i wouldnt buy an rc as theres a lot of guns out lighter and better balanced for the same money. it shoots well, functions as it should, but abit like most tactical look guns they dont fit humans too well !
