Things I liked:the feel and design fit for any cqb combat scenario amazing firing rate and the damage it can do when aimed at center mass, truly worth the money whether your a pro at your operations or a beginner this gun is truly worth the money on the field, the range and for anything up close and personal Things I would have changed:larger magazine,everything else seems squared away. What others should know:buy extra magazines!!!!!!!!!!! and batteries would come in handy!!!! reflex sights!!!! shoots beautifully with 0.20g bbs in addition just have fun..
