so i've seen a rifle that seems nice, a luxus. good nick etc. thing is it has this PONCY barrel- some sort of spiral thing going on (forgive ignorance) and the barrel is rather shiny. is this beneficial or just a tarts handbag? are the luxus' any good as a no non-sense working rifle? reliable? i know that stery's have a good reputation as a rule. it's about three years old.
