      20. Hold a fingertip over the hole on top of the group at the rear to arrest the safety spring, and drift the small cross pin at upper rear toward the right until the hole is cleared. Remove the safety spring and plunger upward, and push out the safety button toward either side. If the plunger fails to come out with the spring, tap the trigger group on the workbench to free it. The other small cross pin at the rear of the group is a limit pin for the trigger. It retains no part, and need not be removed in normal takedown.

      21. The carrier latch and its spring are retained inside the right wall of the lower receiver by a vertical pin which is pushed out upward. Only half of the lower tip of the pin is accessible, and a very small screwdriver or an opened paper clip should be used to push the pin. Restrain the carrier latch.

      22. After the pin is pushed out, remove the carrier latch from the lower receiver. The spring is easily detached from the carrier latch, if necessary.

      23. An ordinary socket wrench can be used to remove the nut under the buttplate that retains the stock. The exact size of the nut is 13mm, but if no metric socket is available, a standard 1/2-inch socket will work. Take off the nut, lock washer, and spacer washer, and remove the buttstock toward the rear..

      24. Drifting out the vertical roll pin at the rear of the recoil spring housing will release the stock mounting bolt for removal toward the rear. Caution: The stock bolt is also the retainer for the recoil spring, so restrain it during removal Take out the spring and follower toward the rear. No attempt should be made to remove the spring housing or the magazine assembly from the lower receiver.

      Reassembly Tips:

      1. When replacing the safety button in the trigger group, remember that the end with the red band goes on the left side.

      2. When replacing the carrier spring base in its recess on the left side of the trigger group, note that the hole in the base is off-center. The end nearest to the hole must go toward the outside-that is, to the left. Also, the flat face of the base goes to the front.

      The bolt head must be pushed to its rear position in the carrier before the cocking handle can be reinserted.

      When replacing the two rings in the front of the forend, the plain ring goes in first, and the spring ring at the front.

      When moving the barrel and receiver assembly toward the rear, be sure the rear tip of the recoil spring strut on the bolt carrier engages the cup of the spring follower.

Benelli Nova

      Similar/Identical Pattern Guns The same basic assembly/disassembly steps for the Benelli Nova also apply to the following guns:

       Nova Slug Gun,

       Rifled Slug Gun.

Data:	Benelli Nova
Origin:	ltaly
Manufacturer:	Benelli Armi,Urbino, ltaly
Gauge:	12 only
Magazine capacity:	4 rounds (2 3/4-inch shells), 3 rounds (3 1/2 inch shells)
Overall length:	49-1/2 inches
Barrel length:	28 inches (others offered)
Weight:	8 pounds.

      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 СКАЧАТЬ
