Principal parts. The weapon has the following principal parts: barrel, barrel sleeve, receiver with back piece and firing mechanism, pistol grip, butt stock, front sight and rear sight, bolt with cocking handle and recoil spring and magazine. The barrel is mounted in the receiver and is secured by the barrel sleeve. Dismantling see page 15. The barrel sleeve is provided with a nut for screwing on to the receiver.‘) On the barrel sleeve there are front sight with catch spring, front sight guard and front sling swivel. The receiver carries the bolt and the firing mechanism. On its rear part there are back piece,‘) a bracket with a catch far butt stock and a rear sling swivel. In the front part the receiver is threaded for the barrel sleeve nut and provided with a guide pin and a catch for the barrel sleeve nut. On the upper side the rear sight is to be found and on the under side, the magazine guide, a magazine catch and a trigger guard. Internally the receiver is provided with an ejector. Furthermore there are locking slots for the back piece, manoeuvre- and safety slots for the cocking handle, and an ejector hole. The firing mechanism is located in the lower part of the receiver and consists of trigger and sear, which is kept in a hooked position by the sear spring. The pistol grip has two wooden grips. The butt stock is fixed in an open position by a catch. The butt stock is provided with a cheek guard. The front sight and the rear sight are of an open type. The rear sight is a flap sight adiustable for 100, 200 and 300 m. The front sight can, when a new barrel is moun- ted, be given different adjustment by means of a front sight key, vertically and laterally. 8
The bolP) has an action face with an integral firing pin in the front part, feed rib and slots for- extractor and ejector. On the underside at the back there are a cocking bent and a transverse hole, in which the cocking handle is mounted. The rear part is shaped as a support for the recoil spring. The extractor is movable against a spring being held by a plate. The bolt can be locked in the front position by pressing the cocking handle into a hole on the left side of the receiver. The magazine is a rod magazine for 36 cartridges. The magazine is provided with holes so that the number of the cartridges can be judged approximately. ‘1 Dismantling see page 15. HANDLING How the gun The works. boll The tion action of the gun is based on the blow back-heavy system. cocking handle is pulled back to the cocked posi- at which the recoil spring is compressed, and then a loaded magazine is inserted in the magazine guide until it locks. When the trigger is pressed, the heavy bolt is released and is driven forward by the recoil spring. The feed rib on the bolt strips the top cartridge from the maga- zine and drives it into the firing chamber. The extractor, which is attached to the bolt, snaps into the cannelure in the cartridge case and the firing pin strikes the cartridge primer exploding the powder. The momentum of the heavy bolt and the spring keeps the bolt in forward position, until the bullet has left the barrel and the pressure in the barrel has dropped to safe limits. The remaining pressure drives the empty cartridge case and moving parts to the rear. The case strikes against 9
