Note that it is not necessary to remove the empty clips manually. The bolt moving forward will hit the bottom of the clip and tilt it out of the weapon. Continued pressure on the bolt handle will cause the face of the bolt to strip the top cartridge forward and chamber it. Turning the bolt handle down when the forward action is completed will lock the lugs at the forward ends of the bolt cylinder securely in their receiver recesses and will complete by cam action the cocking of the rifle as already described.
As the bolt rides over the magazine, the magazine spring acting through the follower can force the cartridges up in line ready for the next loading stroke.
The rear part of the receiver forms a complete cylinder in which the bolt moves; while beyond this cylindrical point it is prolonged into a tang provided with a groove for the cocking stud.
The receiver is further cut out below to receive the magazine, and there is a cut in the tang to receive the tooth of the sear where it projects into the groove for the cocking stud.
The bolt itself is exceptionally strong and of very simple construction. It is made in one piece, hence the bolt head is not removable as in early models and in most Mannlicher designs. No tools are needed to dismount it. The locking lugs at the front end of the bolt are placed opposite one another, providing a breech lock directly and firmly behind the head of the cartridge case. This is the most substantial form of breech locking ever devised. All later important military rifles with the sole exception of the British utilize this form of locking. The British "Pattern 1914" used Mauser-type locking, but all the earlier Lee-Enfields and the new Marks of British service rifles retain the old Lee rear lug system.
The face of the bolt is recessed to receive the base of the rimless cartridge. The bolt handle projects at right angles from the rear of the right side of the bolt and ends in a round knob.
A cam-shaped recess at the back end of the bolt serves to partly cock the striker when the bolt handle is turned up; a thrusting movement being imparted to the cocking-piece and striker which cannot turn, as they are acted upon by the turning bolt cylinder. On the opposite side there is a small notch for the tooth of the safety bolt.
The mainspring if of coiled wire, usually 28 coils, measuring .06 inch in thickness.
The striker is provided with a short point and a collar against which the mainspring bears for cocking. The end of the striker is threaded to receive the cocking-piece.
On the under side of this cocking-piece is a projection traveling in a groove cut for it in the tang of the body. This projection engages with the sear nose when the rifle is at full cock. Its front top surface is beveled off to work in a cam slot in the rear of1 the bolt.
The bolt plug screws loosely into the rear end of the bolt with the mainspring bearing against the front end. The cocking stud working in a slot prevents the bolt plug (or cocking-piece) from revolving with the bolt when the bolt lever is raised.
A rib on the striker prevents the striker from turning in the bolt plug. There is a cylindrical hole in the top of the bolt plug to receive the stem of the safety bolt. The front of the stud on the cocking-piece rests in a small groove at the rear of the bolt and prevents the bolt plug from turning should the safety bolt not be holding back the cocking-piece.
The safety bolt itself is a thumb-piece and a spindle working in the hole in the bolt plug. When the rifle action is closed, and the thumb-piece turned vertical, the flange on the safety bolt is pushed up in front of the top of the cocking-piece to force it back a short distance and enable it to withdraw the stud from contact with the sear. When the thumb-piece is turned to the right, the cocking-piece is still locked,
