The KJW M700 Gas Sniper Rifle is a wonderful replica of the Remington 700 rifle that the Army uses as the base for the M24 and the Marines use as the base for the M40. This rifle can achieve a velocity of 550 FPS on green gas and is VERY easy to use. The magazine holds 10 rounds, which should be more than enough for this rifle. This rifle is very comfortable to shoulder and sight down, and is a joy to shoot. You will be very pleased with this rifle!
