An excellent exercise in modern design and polymer construction, the Benelli Nova was introduced in 1999. One of its notable features is a magazine cutoff button that is located at center underside on the forend, allowing a load change with the other rounds kept in reserve. Overall, the Nova is a beautifully-engineered design.

Disassembly:

1. Cycle the action to cock the internal hammer, and set the manual safety in on-safe position. Unscrew the magazine end cap. Operate the slide latch, and move bolt slightly toward the rear. Remove the barrel toward the front.

2. Use a drift punch, or the provided nose on the maga-zine end cap, to start the trigger group cross pins out toward the left.

3. You can drift the pins all the way out, or use the flange on the inside of the magazine end cap to pull them out. Note, for reassembly, that the cross pins are not of equal length.

4. Tilt the trigger group downward at the rear, and take it out rearward and downward.

5. Push on the top of the action bars to tilt them away from their engagement with the bolt, and take out the action slide assembly toward the front.

6. The action bars are retained in the forearm by two short pins that are not routinely removable.

7. The magazine cutoff button can be taken out, inward, by inserting a tool inside to depress its detent plunger. Caution: control the plunger and its coil spring.

8. With the bolt at the rear of the receiver, compress the bolt head into the bolt body, and lift the assembly out.

9. By repeatedly drawing back the ejector and releasing it to strike its roll-pin retainer, it is possible to push out the pin, and remove the ejector and its long coil spring. If this is done, keep a finger near the retainer pin, to arrest it and prevent loss.

10. The magazine spring and follower can be removed in the usual way, by prying out the retainer at the outer end of the tube. Caution: Control the retainer and spring.

11. Restrain the firing pin, and pull out the firing pin retainer. Note that the retainer has a rubber 0-ring at its head, and be sure this isn't dislodged.

12. Remove the firing pin and its spring.

13. It is possible, if necessary for repair, to drift out the large cross pin that retains the bolt head in the bolt. The pin, however, is heavily factory-staked in place. In normal takedown, it should be left in place. If it must be taken out, it is drifted toward the left, in the direction of its staked head.

14. The extractor is pivoted and retained by a roll-pin, which is drifted out downward. Restrain the extractor during removal, and take out the extractor and its coil springs

15. Restrain the hammer, pull the trigger, and ease the hammer down to fired position. Insert a sharp tool beneath the rounded part of the spring clips on the left end of the trigger group cross-pin sleeves, and tip off both spring clips. Restrain them, and take care that these small parts are not lost.

16. Moving it evenly at front and rear, remove the left sideplate. The front portion of the sideplate is the secondary shell stop.

17. Using a rod or drift of appropriate size, push the front cross-pin sleeve just far enough toward the right to free the hammer.

18. Remove the hammer upward.

19. Restrain the bolt latch and hammer spring, and remove the front cross-pin sleeve toward the right.

20. Move the bolt latch slightly rearward, and slowly release the hammer spring tension. Remove the hammer spring and plunger upward.

21. Remove the rear cross-pin sleeve and take off the right sideplate. Note that the front of the sideplate the primary shell stop, and that it has a tab that engages a recess inside the front extension of the trigger group housing.

22. Move the carrier assembly forward, and tip it downward for removal. Note that the carrier dog retaining pivot is held in place only when in its slot in the group housing, so take care that it doesn't fall out.

23. Turn the carrier over your hand, and the dog pivot will fall into your palm. The dog can now be taken off.

24. Remove the carrier plunger and spring.

25. Push out the trigger cross pin.

26. Remove the trigger assembly upward.

27. Detach the trigger spring from its stud on the dis- connector. urn it clockwise (top view) to remove it from the trigger stud.

28. The disconnector is easily lifted off its pivot pin on the trigger. The pin should be left in place.

29. Use a small tool to push the bolt latch spring retaining pin outward for removal. Restrain the spring, as it may or may not fit tightly in its recess.

30. Remove the bolt latch spring, moving it forward and upward.

31. The bolt latch can now be removed upward. Because its lower tip is angled slightly outward, it will have to be gently pried.

32. Restrain the sear, and push out the sear cross pin.

33. Remove the sear and its coil spring upward.

34. If removal of the manual safety is necessary for repair, put the button in on-safe position, and insert a small tool with an L-shaped tip, such as the dental tool shown, to depress its plunger and spring. The safety button is then easily pushed out. Caution: Keep the plunger and spring under control.

Reasssembly Tips:

1. When re-installing the rear cross-pin sleeve, the trigger must be pulled slightly to clear.

2. Insert the front cross-pin sleeve in small increments, getting it through the carrier arm, the bolt latch, the hammer, and so on. Remember to install the hammer spring and plunger before putting in the bolt latch.

3. Remember that the bolt head must be compressed into the bolt body for reinsertion into the receiver. Be sure the lugs on the action slide bars mate properly with their recesses on the bolt.
