Introduced in 1971, the Browning Lever Action Rifle was made at the Fabrique Nationale factory in Belgium during the first year. Since 1972, it has been produced for Browning Arms by Miroku of Japan. A “Long Action” version was introduced in 1991 for cartridges with more length. In 1990 there was a slight modification of the internal portion of the lever system, but this does not affect the takedown sequence.

Disassembly

1. Remove the magazine. Back out the two screws in the recoil pad, and remove it. With a long-shanked screwdriver or a stock tool, as shown, unscrew the stock mounting bolt. Remove the buttstock toward the rear.

2. The housing that contains the hammer spring and its follower is screwed into the receiver at the rear. It is factory-sealed in place, and it is best not to remove it, as the takedown can proceed without disturbing it.

3. The three main cross pins in the receiver are splined at the right tip, and they must be driven out toward the right. These are large pins with domed heads, and a bronze drift of the proper size should be used to avoid marring. Drift out the hammer pivot pin toward the right.

4. Through the frame opening on the right, grip the hammer strut and move it rearward, then turn it upward at the front. Remove the hammer and the strut upward. The hammer spring follower will be stopped by a stud in the bottom of the receiver.

5. Drift out the lever pivot pin toward the right.

6. Drift out the bolt gear pin toward the right.

7. Remove the lever and bolt gear assembly downward.

8. Remove the bolt gear spacer disc from the gear.

9. Remove the bolt gear from the lever assembly.

10. The lever latch and its spring are retained in the lever by a roll pin. Caution:The spring is powerful, so control the latch.

11. A cross pin retains the trigger assembly and the coil trigger spring.

12. The sear connector is retained in the top of the trigger by a cross pin. If necessary for repair, the cross pin and the connector can be removed without taking the trigger out of the lever.

13. There is a trigger adjustment screw in the lever. This is set at the factory, and changes in the adjustment should be done only by an authorized Browning repair station.

14. Remove the bolt toward the rear.

15. Turn the bolt head clockwise (front view) until it stops, and remove it toward the front.

16. Remove the firing pin return spring toward the front.

17. A roll pin retains the firing pin in the bolt. The firing pin is removed toward the rear.

18. Tip the extractor outward for removal.

19. Remove the extractor plunger and spring from the bolt head.

20. The ejector is stained in the bolt head by a cross pin. Caution:As the drift is taken out, control the ejector—the spring is very powerful.

21. Push out the sear pivot pin.

22. Remove the sear and its spring downward.

23. Drifting out this cross pin toward the right will release the magazine catch and its spring for removal downward.

24. Drift out the barrel band cross pin toward the right.

25. Remove the barrel band toward the front.

26. Remove the large screw at the front of the forend.

27. Remove the forend toward the front.

28. The outer spacer ring will usually stay on the forend mounting bolt. If the inner spacer ring needs to be removed, it is easily lifted out of its recess in the forend.

29. The forend mounting rod is retained on a post at the front of the receiver by a roll cross pin.

30. The rear sight is retained on top of the barrel by a vertical screw. The front sight may be drifted out of its dovetail toward the right. The front sight ramp is not routinely removable.

Reassembly Tips:

1. When replacing the barrel band, be sure the hole with spline marks is on the right side, and replace the pin accordingly. Be sure all of the cross pins are driven in from right to left, with the splined head on the right side.

2. When reinstalling the bolt head, be sure the extractor is oriented toward the right side, as shown.

3. Insert the lever assembly with the bolt in fully closed position, and with the bolt gear at the rearmost location in its track, as shown.

4. Insert the gear and lever cross pins, but do not drive them into place until the gear and bolt engagement is correct. There should be a very small space visible at the point indicated with the lever closed. If the space is measurable, as it is here, then the engagement must be readjusted. To do this, pull the lever pin only, and reposition the lever track on the gear until the bolt closure is correct. If it is too tight for full lever travel, back it off by one gear tooth.

5. As the hammer is reinstalled, the trigger must be pulled fully to the rear for sear clearance, and the strut must be manipulated into proper contact with the hammer and the hammer spring follower. Important:As the hammer pivot pin is reinserted, a tool must be used from the opposite side to depress the lever lock, which uses the hammer pin as a locking surface.
