hey team, question about the 'sport' model lower. i went around looking for the rifle and everyone was out of stock (no surprise). one dealer told me the reason they were so inexpensive was because the lower was made of a composite material. i asked if he was sure and he said that he's had his hands on it and sold a few. from what i read, the upper and lower are 7075 T6 Aluminum, fully-forged in-house by Smith & Wesson. i'd like to hear from actual owners of the 'sport' model. thanks guys!
