Bear Archery G3 Compound Bow

Ive got a Bear Archery G3 compound bow that i purchased two weeks ago ( IVE GOT THE RECEIPT) with 5 high end arrows. This very high quality bow is a RTH ( Ready To Hunt) package, meaning its already furnished with premium Trophy Ridge features like a whisker biscuit, a fibre optic sight, and a stabilizer. Im a hunter and ive always used a rifle, I figured id try something new but im an older guy and my shoulder gave out after about 5 draws. So, im willing to lose a little money on this one if it means itll actually get some use instead of sitting in my safe for the next 30 years cause its literally useless to me given my shoulder. I have receipts proving that i purchased it 2 weeka ago. Bow and Arrow and a couple other things for $400...this bow usually goes for $599.00
