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 M3 SUPER 90 shotgun features a rolling bolt locking head that is simple and sturdy and that with two locking lugs achieves a positive breech lock. This shotgun also uses a loading system that was designed to: - allow manual shifting of cartridges from the tubular magazine to the barrel whether in semi-automatic or pump action mode; - insure quick and safe re-loading; - indicate whether the hammer is cocked and the shotgun ready to fire.
6 Assembly c (from packaged gun) Components of the package (fig. 1): b a a) stock-receiver-bolt-fore-end unit b) barrel-breech unit c) barrel-magazine tube retaining ring. 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) Remove the front cap together with the sling swivel from the tubular magazine (fig. 4).
7 4) Releasing the cocking lever, push the barrelbreech unit with your hand until it clicks into place and is firmly seated (fig. 8). 5) While keeping the barrel-breech unit firmly pressed with your hand, lightly open and close the bolt by sliding the fore-end lever (fig. 9) to make sure that the barrel is properly mounted. If the bolt does not open or close, repeat the two previous steps. 6) Slide the sling swivel over the tubular magazine until it touches the barrel ring (fig. 10).
8 8) Slide the barrel-tubular magazine retaining ring over the barrel and tubular magazine (fig. 14) until it is seated in its recess on the tubular magazine itself and fasten it in that position (fig. 15) by gently tightening the screw. 15 Action selection The type of action on which the M3 SUPER 90 shotgun operates can be selected according to the ammunition being used.
9 To close the bolt again it is necessary to press the carrier release (fig. 18), freeing the bolt to snap forward. The weapon is semi-automatic operated when the selection ring is fastened to the barrel ring (fig. 19) and disconnected from the bolt- swivel unit. In this mode of operation the fore-end lever is stationary relative to the barrel and the bolt can be opened all the way with the cocking lever (fig. 20). 18 21 19 22 20 23 To close the bolt the carrier release must be pressed (fig.
10 B) from semi-automatic to pump action: 1) With the bolt closed (fig. 18), turn the selection clockwise as far as it will go with the thumb of the hand holding the weapon (fig. 22). 2) Keeping the selection ring in the position shown in fig. 22, pull back the fore-end lever until the selection ring is disconnected from barrel ring (fig. 21). 3) Release the selection ring which will rotate counterclockwise until it reaches its normal resting position (fig. 16).
11 2) With the bolt closed and the hammer cocked, reverse the gun pointing the barrel downwards. 3) Insert a cartridge into the magazine (fig. 28): push it until it is retained by the carrier latch which engages automatically (fig. 29). Repeat the operation until the magazine is fully loaded. 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.
12 Cartridge replacement (This operation must be carried out with the gun safety catch engaged - see “Gun safety catch” and barrel pointed in a safe direction) The round in the chamber may be manually replaced with a different round from the magazine or another round by following the steps outlined below, depending on the type of action selected. 2) Insert the new cartridge, even partially, into the chamber through the ejection port (fig. 33) and close the bolt (fig.
13 Unloading B) semi-automatic action (This operation must be carried out with the gun safety catch engaged - see “Gun safety catch” and the barrel pointed in safe direction) The steps listed for unloading in pump-action operation also apply to semi-automatic action. Obviously the bolt must be opened by pulling back the cocking lever (fig. 20) and not the foreend lever.
14 Troubleshooting Ammunition 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). The Benelli M3 SUPER 90 shotgun, when operating in semiautomatic mode, uses the kinetic energy generated by the recoil to work the action. Maintenance 1) Check the safety catch: if it is engaged, push the button to the fire position. Choice of ammunition 2) Check that there is a cartridge in the barrel.
15 2) the firing mechanism, consisting of hammer, trigger, etc., may become clogged with any powder residuals (or foreign matters).
16 7) Pull the cocking lever off with a firm tug (fig. 39). 8) Remove the bolt-swivel unit from the receiver and slide it off the tubular magazine (fig. 40), being careful not to drop the bolt unit once it is out of its guides (fig. 41) and separated from the swivel. 9) Separate the swivel from the bolt unit (fig. 42). 39 42 40 43 41 44 10) Pull the firing pin retaining pin out of the bolt unit, being careful not to let the unretained firing pin be pushed out of the bolt by its spring (fig. 43).
17 12) Remove the locking head rotating pin from its seat (fig. 45). 13) Remove the bolt locking head from the bolt (fig. 46). 14) Remove the recoil spring from its seat in the bolt (fig. 47). 15) 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. 48). 47 16) Press the carrier button and extract the trigger guard assembly towards the front (fig. 49). The shotgun is now completely stripped.
18 Shotgun assembly For correct assembly after cleaning and maintenance operations, proceed as follows: 1) Grip the stock-receiver assembly and press the carrier button so that the whole protection cover unit is simultaneously fitted into the receiver (hammer must be cocked) and is kept in a slightly advanced position compared to its final position (fig. 50).
19 5) Insert the locking head pin in its hole on the locking head’s stem, through the slot on the bolt (fig. 55). NOTE: the reference line on top of the pin must be visible and aligned with the bolt assembly longitudinal axis (fig. 55). 6) Insert the firing pin and the firing pin spring inside the bolt hole (fig. 56). NOTE: always make sure that the firing pin spring has been mounted. 56 59 57 60 58 61 7) Insert the firing pin retaining pin in its seat, so as to block the firing pin (fig. 57).
20 10) Push the cocking lever into its seat hole on the bolt until it fits perfectly (fig. 3). M3 TACTICAL TELESCOPIC STOCK 11) Slide the selection ring-fore-end lever unit over the tubular magazine (fig. 62), the swivel (fig. 63) and its guide (fig. 64). Assembly 12) Rotate completely clockwise the selection ring with the thumb of the hand holding the fore-end lever and pull the whole assembly back until the selection ring engages the swivel (fig. 65).
21 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). 69 Stripping procedure As for the operations from point 1 to point 6, please refer to the M3 SUPER 90 version to page 15 of this manual. 7) Twist and pull off the cocking lever (fig. 67).
22 Shotgun assembly For correct assembly after cleaning and maintenance operations, proceed as follows: 1) Lift the stock-receiver assembly as far as the receiver and press the carrier button, insert the complete trigger group - with cocked hammer - on the receiver in slightly forward position, then draw it back until engaged in the rear of the receiver itself (figs. 72-73). 72 75 73 76 74 77 2) Block the trigger guard assembly using the special axle (fig. 74).
23 Rear sight adjustment The rear sight can be adjusted for both windage and elevation if the standard factory setting does not meet shooter requirements. 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).
24 2) Hold the limiter and retaining ring and allow them to be forced out of the magazine by the magazine spring. 3) Completely remove limiter and retaining ring from magazine. To install the limiter, proceed as follows: 1) With the gun unloaded, point barrel upwards and insert the limiter into the appropriate fitting hole (fig. 82).
25 WARNING: before using the shotgun, make sure that the barrel has a choke correctly installed. WARNING: the internal choke correctly mounted must not stick out of the barrel’s muzzle. Use only the Benelli internal chokes with a length which correctly fits the barrel. Before the shotgun is put away, cleaning the internal choke and relative barrel thread is recommended. Benelli chokes are marked for an easy identification (fig. 89).
26 Magazine tube extension Where capacity increase is required for short magazine tube shotgun versions, magazine tube extension kits are available upon request. For the assembly of the extension kit, proceed as follows: 1) Completely unscrew the forearm retainer cap and withdraw it from the magazine. 2) Remove the magazine spring retaining ring.
27 Rear sight adjustment (ghost sight) Windage (lateral) adjustment The rear sight can be adjusted for both windage and elevation if the standard factory setting does not meet shooter requirements. Using a coin or the rim of a shell cartridge to rotate the windage adjustment screw (fig. 91), located on the right side of the rear sight assembly, in the desired direction.
28 Rear sight adjustment (open sight) If the standard factory settings do not meet individual firing requirements, it is possible to adjust the windage of the rear sight. For the adjustment of the rear sight proceed as follows: 1) Using the wrench provided, slacken the two sight screws (fig. 94). 2) Adjust the sight position as desired and fully tighten the two screws (fig. 94). 3) If the new rear sight setting does not meet your shooting requirements, repeat the process.
