2 WARNING: PLEASE READ THIS MANUAL BEFORE HANDLING YOUR FIREARM. WARNING: FIREARMS CAN BE DANGEROUS AND CAN POTENTIALLY CAUSE SERIOUS INJURY, DAMAGE TO PROPERTY OR DEATH, IF HANDLED IMPROPERLY. THE FOLLOWING SAFETY RULES ARE AN IMPORTANT REMINDER THAT FIREARM SAFETY IS YOUR RESPONSIBILITY. 1. NEVER POINT A FIREARM AT SOMETHING THAT IS NOT SAFE TO SHOOT. Never let the muzzle of a firearm point at any part of your body or at another person. This is especially important when loading or unloading the firearm.
3 Make sure the chamber and barrel are free from any obstruction, like a bullet blocked inside the barrel due to defective or improper ammunition. 7. USE PROPER AMMUNITION. Only use factory-loaded, new ammunition manufactured to industry specifications: CIP (Europe and elsewhere), SAAMI® (U.S.A.). Be certain that each round you use is in the proper caliber or gauge and type for the particular firearm.
4 Introduction Operation Benelli Armi S.p.A. is proud to introduce the line of semi-automatic shotguns, a result of painstaking work at Benelli’s Research and Development Center and of Benelli’s extensive experience in precision engineering and technical know-how.
5 The pull action is carried out in a smoothly and controlled way, without trigger slack or sudden relax after releasing the hammer, thus ensuring efficacy and safety of the whole system. As the cartridge falls into position on the carrier, it presses against the “cartridge drop lever” which rotates in the opposite direction to prevent a second cartridge from exiting.
6 Assembly (from packaged gun) b a Components of the package (fig. 1): a) stock-receiver-bolt-fore-end unit b) barrel-breech unit WARNING: please remember to remove the plastic barrel sheath before using the firearm (fig. 2). 1 4 2 5 3 6 Assembly procedure 1) Insert completely the cocking lever into the breech bolt unit (fig. 3). 2) Unscrew the fore-end cap and remove from the magazine tube (figs. 4-5).
7 4) Remove the red plastic bolt clip from its seat in the receiver (fig. 7). NOTE: the red plastic clip is used to retain the bolt during shipping only. It must not be reinstalled on the gun. 5) Take the stock-receiver-bolt unit with a hand; with the other hand, using the cocking lever, bring the bolt into open position (until locked) (fig. 8). 7 10 8 11 9 12 WARNING: should the bolt fail to engage, move the cartridge drop lever as arrowed and repeat the operation (fig. 9).
8 8) As the barrel extension nears the bolt group, carefully align the barrel extension (sight) with the top of the protruding bolt head. NOTE: during installation, expand the retaining ring slightly so that it can be inserted over the magazine tube without binding. 9) With the barrel extension resting on the bolt head, and the bolt head fitting into the recess formed into the barrel extension, slip the barrel into receiver. A metallic click will indicate the barrel is correctly seated (fig. 13).
9 Gun safety catch Press the safety button on the trigger guard until its red ring, indicating firing position, is no longer visible (figs. 18-19). Loading 1) The red dot on the cartridge drop lever (indicating that the hammer is cocked) (fig. 20) must be clearly visible. To bring lever to this position, press the carrier button and open the bolt by hand, then bring it to close position again (fig. 21). 2) With the bolt closed and the hammer cocked, reverse the gun pointing the barrel downwards.
10 3) Insert a cartridge into the magazine (fig. 22): push it until it is retained by the carrier latch which engages automatically (fig. 23). Repeat the operation until the magazine is fully loaded. Cartridge replacement NOTE: the gun must be loaded with the hammer cocked so that the carrier latch can retain the cartridges as they are inserted in the magazine.
11 Unloading Troubleshooting (This operation must be carried out with the gun safety catch engaged - see “Gun safety catch” and the barrel pointed in safe direction) To unload the shotgun, proceed as follows: Before starting any operation on your shotgun, make sure that the chamber and the magazine are unloaded! (Carefully read the instructions on gun loading and unloading). 1) Engage the safety catch and pull the cocking lever to open the bolt (fig.
12 Ammunition The Benelli semi-automatic use the kinetic energy generated by the recoil to work the action. Use always ammunition that is powerful enough to fully cycle the action. WARNING: when your shotgun is new and before beginning to use it normally, a breaking-in period may be required before your new gun works perfectly with light target loads. If you experience any initial functioning problems, we recommended firing three or four boxes of standard hunting cartridges.
13 Shotgun stripping (for cleaning and maintenance) Before starting any operation on your shotgun, make sure that the chamber, carrier and the magazine are unloaded! (Carefully read the instructions on gun loading and unloading). Stripping procedure 1) Slacken the screw and remove the barrelmagazine tube retaining ring (fig. 16) from its seat on the magazine tube (only in versions equipped with long magazine tube or with magazine tube extension).
14 7) Pull the cocking lever off with a firm tug (fig. 35). 8) Pull the bolt assembly out of the receiver, sliding it along its guides (fig. 36). 9) Remove the firing pin retaining pin from the bolt assembly, while holding the firing pin and firing pin spring in place (fig. 37). 10) Remove the firing pin and firing pin spring from the bolt (fig. 38). 35 38 36 39 37 40 11) Remove the locking head rotating pin from its seat (fig. 39). 12) Remove the bolt locking head from the bolt (fig. 40).
15 13) Remove the recoil spring from its seat in the bolt (fig. 41). 14) Extract the trigger guard pin from the stockreceiver unit, thrusting it from right or left with the point of the same firing pin or punch (fig. 42). 15) Press the carrier button and extract the trigger guard assembly towards the front (fig. 43). The shotgun is now completely stripped. All the parts that require routine maintenance and cleaning are disassembled.
16 3) Place the bolt recoil spring in its seat on the bolt (fig. 47). NOTE: always make sure that the bolt recoil spring is positioned between the locking head and the bolt itself, in order to avoid a shot being fired during the closing phase. 4) Slide the locking head into the bolt, making sure that the hole on its stem coincides with the slot on the bolt (fig. 48). 47 50 48 51 49 52 WARNING: the slanted surfaces on the locking head’s stem should not be visible once the bolt locking head is mounted.
17 WARNING: make sure that the bolt link slides over the trigger guard assembly, positioning on the recoil spring guide pin inside the receiver, once the mounting has been completed (fig. 53). 9) Draw back the bolt head and insert completely the cocking lever into the bolt group (fig. 54). 10) Finish assembling the shotgun by following all the steps (except the first four) outlined under the section on page 7.
18 The shotgun is supplied with a “drop change kit” (fig. 55) which enables you to adjust the original drop the shotgun is supplied with. The kit consists of one stock locking plate (in steel), plus drop change shims three (in plastic). 1 23 4 8 5 The kit enables you to obtain four different drop patterns (as specified in the following table) and two different deflections (right hand or left hand). Each unit is marked with the corresponding drop and cast letter.
19 WARNING: if the stock spacer “8” doesn’t remain inside the stock, reassemble it with the seat of plate “4” facing the butt plate. 4) Assemble the drop shim “7” that you have selected onto the recoil spring tube with the stamped letter facing the stock. 5) Reassemble the selected cast shim “6” with the stamped letter (DX or SX) facing toward the stock. 6) Point the barrel towards the floor and fit the stock.
20 Set stock drop Before beginning any operation on your shotgun, always make sure that chamber and magazine are unloaded! (Carefully read the instructions on gun loading and unloading). A stock version with fixed drop is available: - “Pistol Grip” type stock. 61 64 62 65 63 66 To change stocks proceed as follows: 1) Press on the butt plate and simultaneously exert a movement from below upwards (figs. 61-62).
21 6) Point the gun towards the ground and install the pistol-grip stock over the recoil spring tube. Make sure that the recoil spring tube is aligned with the hole on the swivel plate (fig. 67). WARNING: when correctly installed, the pistolgrip stock will mate to the rear of the receiver, and the swivel plate will be tight in its seat. 7) Before turning the stock nut in onto the threaded stud protruding from the inside of the rear of the stock, fit the rubber washer into place (fig. 68).
22 To remove the limiter proceed as follows: 1) With the gun unloaded, point the barrel upwards. Using the index finger of your hand, remove the limiter retaining from the magazine tube (fig. 71). To facilitate removal, rest your right thumb on the magazine tube and turn the retaining ring until one of the tabs passes the magazine tube spigot (fig. 72). 4) Reduce finger pressure until the limiter is tight against the tube spigot (fig. 76).
23 Short tube limiter Before starting any operation on your shotgun, make sure that the chamber and the magazine are unloaded! (Carefully read the instructions on gun loading and unloading). WARNING The following operations must be carried out carefully in order to prevent the magazine spring from escaping at high speed. 2) Insert limiter and spring into the magazine tube. 3) Fit the spring seal ring on so that there are no protrusions from the tube.
24 To change or clean the internal choke, proceed as follows: 1) Unscrew the internal choke using the special choke wrench supplied with the shotgun and extract it completely from the barrel seat (fig. 79). 2) If the threaded seat of the choke on the barrel is too dirty, clean it. 3) Reassemble on the barrel seat the kind of choke required, taking care to insert the nonthreaded part inside the barrel, before screwing the choke on the barrel’s thread (fig. 80).
25 Magazine tube extension WARNING Where capacity increase is required for short magazine tube shotgun versions, magazine tube extension kits are available upon request. The following operations must be carried out carefully in order to prevent the magazine spring from escaping at high speed. When carrying these operations out, always wear eye protection. If the magazine spring escapes at high velocity severe eye injury or other injuries with serious consequences can occur.
26 Rear sight adjustment Adjusting the back-sight (12 gauge) (12-20 gauge) The rear sight can be adjusted for both windage and elevation if the standard factory setting does not meet shooter requirements. For the adjustment of the back-sight as illustrated in figure 88, proceed as follows: Before starting any operation on your shotgun, make sure that the chamber and the magazine are unloaded! (Carefully read the instructions on gun loading and unloading).
