Bolt and valve mechanism that uses less gas

摘要: The proposed invention is a new bolt and gas release valve mechanism for projectile launching device, such as paintball marker, that uses significantly less per shot than prior art devices. open chamber between the projectile, paintball, eliminated thereby requiring much to be used each launch of given projectile. Thus, only propel needed not additional required fill in directly behind This enables desirably smaller supply tanks during use same number projectiles. Also, with present invention, more projectiles can launched using tank.
