I run at a great indoor CQB field on Long Island and it is semi only, which I like and believe is better for indoors. you can move around more and play the game better...that is my feelings. I have seen a quick surge of polar star rifles at my field... I hear they are great as far as maintenance and I see how well they fire..... but I am playing against these guys and it is like playing against someone on full auto, they are firing rounds in semi so fast...so fast... (at first I was jealous, lol) But is this good for the game...? now everyone is allowed to get them but not everyone can afford it.... they seem to be great weapons but it is basically playing against full auto... the other day someone was laying suppressing fire down on us so we could not leave a room and it sounded like full auto... is this a good thing..? in a sport that is more milsim based is this closer to the real thing or further... what are your thoughts.....????
