Update: I just noticed it has the top dead center screw on the top rail so I assume this makes it the latest gen. Brand new in box. Full setup. Tippmann m4 carbine gbbr co2 / HPA rifle I own many gbbr and hpa platforms. And between my Daytona guns, Wolverine quake, or standard gbbr rifles, the tippmann m4 has it all. It has the best sound. The best feel, and shoots the best hands down. The co2/hpa design is super versatile allowing you to run a tank and line or use co2 in the mag.
