      Designed by the great John M. Browning just before the turn of the century, this fine gun was introduced in 1900. There have been tiny mechanical changes over the years, but the basic design is absolutely unchanged. At one time, both Remington and Savage made versions of the gun, during periods when the original Belgian model was not marketed in the U.S. The instructions will generally apply to the Remington Model lls, but not to the Savage, which is mechanically different. In this revised edition, the Savage is covered separately.

      Disassembly:

      1. Pull back the operating handle to lock the bolt in the open position, and set the safety in the on-safe position. Depress the barrel slightly toward the rear, and unscrew and remove the magazine end cap. Take off the forend and barrel toward the front.

      2. The ejector is mounted in a T-slot at the left rear of the barrel extension, and is retained by a riveted cross pin. In some models, it is solidly fixed, and in others it has an opening at the center and slides to the rear. In both cases, it should be removed only for repair. The riveted pin is driven out inward.

      3. Remove the bronze friction piece and its attached spring toward the front.

      4. Remove the compression ring toward the front. If the gun has been used with light loads, the ring will be found "stored" at the rear of the recoil spring.

      5. Remove the recoil spring toward the front.

      6. Hold the operating handle to restrain the bolt, depress the carrier latch button, and ease the bolt forward to the closed position. Remove the lock screw, then the stock screw, in the reartip of the lower tang. It should be noted that for all screws on this gun, you will need screwdrivers with very thin blades. If necessary, alter some screwdrivers for this purpose. Remove the buttstock toward the rear. If it is very tight, bump the front of the comb with the heel of the hand or a rubber hammer.

      7. Remove the lock screw, then the main screw on the left side of the receiver, just above the front of the trigger housing.

      8. Remove the lock screw, then the main screw on the left side at the lower rear of the receiver.

      9. Remove the trigger group downward.

      10. Remove the carrier spring from its post on the left side of the trigger housing. Note that on early guns, this spring will be mounted on a post inside the receiver, and must be detached at the front, then moved off its post inward for removal.

      11. Move the safety to the off-safe position, tip the safety sear (arrow) forward, restrain the hammer, pull the trigger, and ease the hammer forward until its roller disengages from the tip of the hammer spring.

      12. Drift out the hammer cross pin, and remove the hammer from the trigger housing.

      13. Remove the hammer spring screw, located on the underside of the rear tang of the trigger housing. Note that the spring is not removed at this time.

      14. Insert a small screwdriver at the front of the safety sear to depress the plunger and spring, and remove the safety sear toward the left. Caution: Keep the plunger under control, ease it out, and remove the plunger and spring upward.

      15. Lift the hammer spring at the front, and remove it upward and toward the front.

      16. Push out the small cross pin in the rear tang of the trigger housing. Removal is easier if the trigger spring is slightly depressed in the vicinity of the pin.

      17. Remove the trigger spring upward and toward the rear.

      18. Invert the trigger housing over the palm of the hand, and move the safety to free the detent ball. If it does not drop out easily, tap the housing with a nylon hammer.

      19. Drift out the trigger cross pin, and remove the trigger upward.

      20. Remove the safety toward the right.
