The Gun with which the batteries of this organization are equipped, is known officially as the j-inch Field Gun, Model TQO$. This gun is a built-up construction of nickel steel and consists of a tube with a rifled bore, 3 inches in diameter, upon which are shrunk the jacket, locking hoop and front clip hoop. The jacket reinforces the rear half of the tube. The locking hoop serves to secure the jacket from any longitudinal movement to the rear. On the under side of the gun, extending the entire length of the jacket, locking hoop, and front clip, are formed two recoil guides or clips which fit over and secure the gun to the guide rails of the cradle. When the gun is fired, it glides along the guide rails. The dust guard covers that part of the guide rails between the locking hoop and the front clip. The rifling of the bore is right hand twist and starts with turns at the breech increasing to 1 turn in 25 calibers at 10 inches from the muzzle, then uniform to the muzzle.
