Original Sharps rifles and carbines, and other modern reproductions.

Christian Sharps patented the basic design of this rifle in 1848. The first metallic cartridge versions were made in 1869. The excellent modern reproductions have only one or two tiny differences in the design. The gun shown here is the Dixie Target/Hunter, a beautiful gun.
Disassembly:
1. Remove the two screws in the fore stock, and take it off downward. If you have an original or military-style gun, there will also be barrel bands with spring-depression locks to be removed.
2. Open the breech to relieve the tension of the lever spring. Remove the screw, and take off the spring.
3. If total takedown is intended, as for refinishing, removal of this screw will allow you to take out the lever pivot pin latch spring and plunger. If this is not the case, see #4.
4. Depress the latch plunger, and turn the arm of the lever pivot out of its lock flange on the receiver.
5. Remove the lever pivot pin toward the right.
6. Remove the lever and the attached breechblock downward.
7. Remove the ejector downward.
8. Removal of this recessed screw will allow the lever and its link to be separated from the breechblock.
9. The link is retained and pivoted on the lever by this cross-screw.
10. Control the firing pin transfer block, and remove the retaining screw.
11. Ease out the transfer block and remove it. On an original Sharps, the firing pin is an integral part of this unit, and there is a screw-retained leaf spring.
12. Remove the firing pin and its return spring.
13. Set the hammer in its mid-position (loading notch), and remove the front lock-plate screw.
14. Remove the rear lock-plate screw. Note that the screws are not identical, so keep them separate for reassembly.
15. Remove the lock-plate.
16. If you do not have a mainspring vise (the one shown is from Dixie Gun Works), it would be wise to avoid disassembly of the lock. After the spring is compressed by the vise, its side-post is pulled out of the lock-plate for removal. Removal of the three screws to the left will release the bridle and the sear. In normal takedown, the hammer and tumbler are not separated.
17. Remove the two large screws in the upper tang of the receiver. Note that they are not of equal length.
18. Remove the wood-screw at the rear of the trigger plate.
19. Remove the screw at the front of the trigger plate.
20. Remove the buttstock from the receiver.
21. Remove the trigger plate from the buttstock.
22. If the trigger assembly is to be taken apart, first remove the trigger springs at front and rear.
23. After the springs are removed, (they are still in place in this photo) drifting out the crosspins will release the triggers to be taken out. The two adjustment screws are best left in place.
24. If the rear sight is to be drifted out of its dovetail mount, first remove the sight spring. The front sight is also dovetail mounted.
25. This screw, on the upper inside of the receiver, is a limit or bearing screw that retains no part. It can be left in place.
Reassembly Tips:
1. When installing the ejector, it goes into its slot in the orientation shown here.
2. For reinsertion, it is best to hook the ejector into the breechblock, as shown.
