Both rifles are about the same in price. The 880 is about $5 more than the 764. The 880 has a 50 round capacity. The 764 has an 18 round capacity. The 880 has a rifled barrel, the 764 has a smooth bore barrel. The 880 is rated at 750 FPS, the 764 is rated at 625 FPS. If it were me I would select the 880 over the 764
