Benelli M4

Benelli Parts

Benelli parts are Original Equipment Manufacturer (OEM) and aftermarket replacement components for Benelli shotguns and rifles, including firing pins, extractors, carriers, sights, choke tubes, recoil pads, stocks, forends, magazine caps, and bolt handles. Benelli Armi S.p.A., a subsidiary of Beretta Holding, manufactures semi-automatic shotguns, pump-action shotguns, over/under shotguns, and semi-automatic rifles across 18 firearm models. Benelli parts divide into 2 platform categories: shotgun parts for the M-Series tactical lineup (M1 Super 90, M2, M3, M4), the hunting lineup (Super Black Eagle 3, Ethos, Montefeltro, Cordoba, Supersport, Sport II, Legacy, Ultra Light, Vinci, Super Vinci, Nova, SuperNova, 828U, SL-80), and rifle parts for the Benelli LUPO bolt action, R1 semi-automatic, and MR1 tactical rifle. TactaBlue stocks Benelli parts from Benelli USA, Freedom Fighter Tactical (FFT), and Midwest Gun Works for current and discontinued Benelli firearm models.

Benelli M-Series Tactical Shotgun Parts

Firing Pin Components

Benelli OEM firing pin components maintain reliable primer ignition in the Benelli inertia-driven and Auto-Regulating Gas-Operated (ARGO) action systems. There are 3 OEM firing pin components for Benelli tactical shotguns.

• OEM Benelli Firing Pin (part number 60180, $60.00) — drop-in replacement firing pin for the M1, M2, M3, M4, Nova, SuperNova, Super Black Eagle (SBE), and Montefeltro bolt assemblies
• OEM Benelli Firing Pin Spring (60179, $24.00) — replacement spring that returns the firing pin to the retracted position after each hammer strike
• OEM Benelli Firing Pin Retaining Pin (60178, $22.00) — cross-pin that secures the firing pin inside the bolt body and prevents the firing pin from rotating during cycling

Replace the firing pin spring every 5,000 to 10,000 rounds or when light primer strikes occur. A worn firing pin spring allows the firing pin to travel forward with insufficient force, which causes misfires with hard-primered ammunition. Use a 1/16-inch (1.6 mm) roll pin punch to drive out the firing pin retaining pin during disassembly.

Extractor Components

The OEM Benelli Extractor (60177, $48.00) is a spring-loaded claw that grips the cartridge rim and pulls the spent shell from the chamber during the rearward bolt travel. The OEM Benelli Extractor Retaining Pin / Rear Sight Pin (60173, $18.00) serves a dual function — the retaining pin secures the extractor in the bolt face and also acts as the rear sight pin on models with fixed rear sights. Replace the extractor when the claw face shows visible wear, chipping, or rounding that causes extraction failures or weak extraction (the spent hull ejects with less force than normal).

Carriers and Carrier Latches

Benelli carriers (shell lifters) transfer shotshells from the magazine tube to the chamber by lifting each shell from the magazine loading port into the bolt path. There are 4 OEM carrier configurations for Benelli shotguns.

• OEM Benelli M1 Tactical Carrier, 12 Gauge, Left Hand (60131, $67.00) — left-handed carrier for M1 Super 90 tactical models
• OEM Benelli Montefeltro 12ga Carrier (60134, $68.00) — standard carrier for right-handed Montefeltro shotguns
• OEM Benelli Montefeltro 12ga Left-Handed Carrier (60127, $65.00) — left-hand carrier for Montefeltro models
• OEM Benelli M3 Carrier (60133, $70.00) — carrier for the M3 dual-mode pump/semi-automatic shotgun

The OEM Benelli M3 Carrier Latch (60132, $109.00) is the spring-loaded latch that retains shotshells in the magazine tube and releases 1 shell at a time onto the carrier during the bolt cycling stroke. A worn or bent carrier latch releases 2 shells simultaneously, which causes double-feed malfunctions. Polish the carrier latch contact surfaces with 800-grit sandpaper to improve shell release timing, if shells hesitate during loading.

Disconnector

The OEM Benelli Disconnector (60155, $53.00) is a trigger group component that resets the trigger mechanism after each shot and prevents the hammer from following the bolt forward during cycling. The disconnector ensures the Benelli fires only 1 round per trigger pull. A worn disconnector causes hammer follow — the hammer drops immediately when the bolt closes without a second trigger pull, which results in an uncontrolled discharge. Replace the disconnector immediately, if hammer follow occurs during firing.

Benelli Sights, Bases, and Rails

Ghost Ring Sight Assemblies

Benelli ghost ring sights provide a fast-acquisition aperture rear sight paired with a front post for tactical and home defense applications on the M1, M2, M3, and M4 platforms. There are 2 OEM ghost ring sight assembly versions based on manufacture date.

• M1 and M3 Rear Ghost Ring Sight Assembly, Pre-1997 ($125.00) — fits M1 Super 90 and M3 shotguns manufactured before 1997 with the original sight dovetail pattern
• M1, M2, M3, and M4 Rear Ghost Ring Sight Assembly, Post-1997 ($190.00) — fits all M-Series shotguns manufactured after 1997 with the updated sight mounting system

Verify the manufacture date of the Benelli shotgun before ordering a ghost ring sight assembly — the pre-1997 and post-1997 sight bases use different dovetail widths and mounting screw patterns that are not interchangeable.

Tritium Night Sight Inserts

Benelli tritium night sight inserts add self-luminous tritium lamp capsules to the ghost ring sight assembly for 24-hour sight visibility without batteries or external light sources. There are 3 tritium insert configurations for different Benelli models.

• M4 Tritium Night Sight Inserts for Ghost Ring Sights ($145.00) — fits the M4 post-1997 ghost ring rear and front sights
• M2, Nova, and SuperNova Tritium Night Sight Inserts for Ghost Ring Sights ($145.00) — fits the M2, Nova, and SuperNova ghost ring sight assemblies
• M1 and M3 Tritium Night Sight Inserts for Ghost Ring Sights ($125.00) — fits the M1 Super 90 and M3 pre-1997 ghost ring sights

Tritium has a half-life of 12.3 years. Tritium night sight inserts provide usable illumination for 10 to 12 years from the date of manufacture. Replace tritium inserts when the glow becomes too dim to acquire in low-light conditions.

Front Bead and Fiber Optic Sights

Benelli front bead sights are threaded or press-fit sight beads that screw into the shotgun barrel rib for a single reference point during wing shooting and clay target sports. The Front Bead Sight in Red ($20.00) fits M1, M2, M3, M4, SBE, and Montefeltro barrels. The Nova and SuperNova Front Bead Sight in Red ($20.00) fits the Nova and SuperNova barrel rib threading. The Mid Bead Sight in Silver ($20.00) installs at the midpoint of the barrel rib as a secondary alignment reference between the front bead and the shooter's eye. The Benelli Ethos 12 and 20 Gauge Front Sight Kit in Green and Yellow ($40.00) includes 2 interchangeable fiber optic front sights for the Ethos barrel rib. Individual Ethos front sights are available in Red ($48.65), Green ($48.65), and Yellow ($20.00).

Benelli Choke Tubes

The OEM Benelli Extended Choke in Mobil Pattern (60145, $145.00) is an extended-length choke tube that threads into Benelli barrels using the Beretta/Benelli Mobil choke system and extends 1 inch (25.4 mm) past the muzzle for tool-free removal by hand. Benelli uses 2 choke tube threading systems across the product line: the Mobil pattern on hunting and sporting models (Montefeltro, Ethos, Cordoba, Ultra Light, Legacy, Supersport, Sport II) and the Crio pattern on tactical and waterfowl models (M2, SBE 3, Vinci, Super Vinci). Mobil and Crio choke tubes are not interchangeable — Mobil chokes use a shorter thread length of 0.579 inches (14.7 mm) and Crio chokes use a longer thread length of 0.720 inches (18.3 mm). Verify the choke system before purchasing replacement choke tubes by checking the barrel marking or the Benelli owner's manual.

Benelli Stocks and Forends

Benelli M4 Collapsible Stock

The Benelli M4 Collapsible Stock (part number 70085, $449.00) is a genuine Benelli factory 5-position collapsible stock that adjusts Length of Pull (LOP) from 11.4 inches (289.6 mm) to 14.6 inches (370.8 mm) on the Benelli M4 tactical shotgun. The M4 collapsible stock uses a steel tube recoil spring system inside the stock body and mounts to the M4 receiver with the factory stock bolt. The Benelli M4 collapsible stock is the same stock issued on United States Marine Corps (USMC) M1014 Joint Service Combat Shotgun (JSCS) contract shotguns. The M4 collapsible stock requires no modification to the receiver and is a direct drop-in replacement for the factory fixed stock. The M4 collapsible stock is a controlled part for 922(r) compliance — verify the total count of imported parts in the shotgun does not exceed 10 foreign-made parts when installing the collapsible stock on an imported Benelli M4.

Stock Adjustment Shims and Kits

Benelli cast change shims adjust the stock-to-receiver angle to change the point of impact left, right, up, or down relative to the sight plane. The 12-Gauge Cast Change Shim ($11.05) and 20-Gauge Cast Change Shim ($11.05) fit between the stock and receiver on Benelli semi-automatic and pump-action shotguns. Shim kits include cast-off shims for right-handed shooters, cast-on shims for left-handed shooters, and drop shims that change the vertical pitch. Stock adjustment shims correct consistent point-of-impact errors without modifying the barrel, receiver, or sights.

Forend and Pistol Grip Components

The FFT Replacement Handguard / Forend Bushing (60190, $15.00) is a polymer bushing that sits inside the forend and rides on the magazine tube, providing a bearing surface that guides the forend during pump cycling on the M3 and during forend removal on semi-automatic models. The Synthetic Stock Swivel Plate ($15.08) mounts to the rear of the synthetic stock and accepts a sling swivel stud for rear sling attachment. The Recoil Spring Tube Plug ($23.52) caps the end of the recoil spring tube inside the buttstock on Benelli semi-automatic shotguns. The OEM Benelli Rubber Pistol Grip (60207, $50.00) is a replacement rubber overmold grip for the Benelli M4 and M1014 pistol grip stock configuration.

Benelli Breaching and Tactical Accessories

The OEM Benelli Tactical Shotgun External Thread Breaching Attachment with Trulock Beretta/Benelli Mobil Adapter (60097, from $295.00) is a muzzle-mounted breaching device that threads onto Benelli tactical shotgun barrels using a Trulock adapter and provides a standoff surface for door breaching with breaching rounds. The breaching attachment is available in Black and Nickel Phosphate 3 (NP3) corrosion-resistant finishes. The NP3 finish provides a dry lubricity coefficient of 0.15 that reduces fouling buildup on the breaching crown. The breaching attachment installs on Benelli M1, M2, M3, and M4 barrels with Mobil-pattern choke tube threading. The OEM Benelli Extended Magazine Cap with Swivel (60192, $98.00) replaces the factory magazine tube cap with an extended cap that includes an integrated front sling swivel for 2-point sling attachment.

Benelli Recoil Management Parts

Benelli recoil pads and recoil reducers decrease felt recoil at the shooter's shoulder during firing by absorbing and redistributing recoil energy. Benelli gel recoil pads attach to the rear of the buttstock with 2 screws and use a viscoelastic gel layer that deforms under impact and returns to shape between shots. Benelli recoil reducers are weighted mercury or spring-damper units that install inside the buttstock cavity and counteract rearward recoil force with a forward-moving mass. The Benelli Comfort Tech stock system on the SBE 3, Vinci, Super Vinci, and Ethos uses 3 interlocking synthetic chevrons inside the stock that flex independently under recoil and reduce felt recoil by up to 48% compared to a standard solid stock. Benelli Comfort Tech 3 stocks on the SBE 3 and Ethos use an updated chevron geometry that distributes recoil across a longer stroke distance.

Benelli Shotgun Platform Overview

Benelli Inertia-Driven Models

Benelli inertia-driven shotguns use a kinetic energy operating system where the bolt body and inertia spring absorb recoil energy to cycle the action without gas ports, pistons, or gas rings. There are 12 inertia-driven Benelli shotgun models.

• Benelli M1 Super 90 — the original Benelli inertia-driven tactical and hunting shotgun (discontinued, parts available)
• Benelli M2 — the current-production inertia-driven semi-automatic in 12-gauge and 20-gauge for tactical, hunting, and competition use
• Benelli M3 — a dual-mode shotgun that operates in semi-automatic inertia-driven mode or manual pump-action mode by rotating a ring on the forend
• Benelli Super Black Eagle 3 (SBE 3) — a 3.5-inch (89 mm) magnum-chambered inertia-driven waterfowl shotgun with Comfort Tech 3 recoil reduction
• Benelli Super Black Eagle II (SBE II) — the previous-generation 3.5-inch magnum waterfowl model (discontinued, parts available)
• Benelli Super Black Eagle (SBE) — the original 3.5-inch magnum model (discontinued, parts available)
• Benelli Ethos — an inertia-driven sporting and upland shotgun in 12-gauge, 20-gauge, and 28-gauge with Progressive Comfort recoil reduction
• Benelli Montefeltro — a lightweight inertia-driven field shotgun in 12-gauge and 20-gauge with a walnut stock
• Benelli Cordoba — a high-volume inertia-driven shotgun designed for dove, pigeon, and clay target sports
• Benelli Vinci — a modular 3-piece takedown inertia-driven shotgun that separates into stock, receiver, and barrel modules
• Benelli Super Vinci — the 3.5-inch magnum version of the Vinci modular platform
• Benelli Ultra Light — a 6.0-pound (2.7 kg) inertia-driven upland shotgun with an aluminum receiver and carbon fiber rib

Benelli Gas-Operated and Pump-Action Models

The Benelli M4 uses the Auto-Regulating Gas-Operated (ARGO) system with 2 stainless steel self-cleaning gas pistons mounted on either side of the magazine tube below the barrel. The ARGO system cycles 2.75-inch (70 mm) and 3-inch (76 mm) 12-gauge shells without adjustment. The M4 is the only gas-operated Benelli shotgun in current production. The Benelli Nova and SuperNova are pump-action shotguns with a one-piece receiver and stock molded from glass-filled polymer. The Nova accepts 2.75-inch, 3-inch, and 3.5-inch (89 mm) 12-gauge shells from a single magazine tube. The Benelli 828U is a 12-gauge over/under shotgun with an aluminum alloy receiver, ejector system, and removable trigger group.

Benelli Rifle Models

The Benelli LUPO is a bolt-action rifle with a sub-MOA (Minute of Angle) accuracy guarantee, available in .308 Winchester, 6.5 Creedmoor, .30-06 Springfield, .300 Winchester Magnum, and .270 Winchester chamberings. The Benelli R1 is a semi-automatic hunting rifle using the ARGO gas system. The Benelli MR1 is a tactical semi-automatic rifle chambered in .223 Remington / 5.56x45mm NATO (North Atlantic Treaty Organization) with a detachable box magazine and Picatinny rail. Rifle parts including magazines, barrels, and bolt components are model-specific and not interchangeable between the LUPO, R1, and MR1 platforms.

Benelli Parts Compatibility and 922(r) Compliance

Benelli shotguns imported into the United States are subject to Section 922(r) of Title 18 of the United States Code, which limits the number of foreign-made parts in a semi-automatic shotgun to 10. The Benelli M4 has 16 countable parts under 922(r). Converting an imported Benelli M4 from the fixed stock to the collapsible stock (part 70085) adds a United States (US)-made part but does not change the foreign parts count unless the collapsible stock replaces a foreign-made fixed stock. Replace a minimum of 6 foreign-made parts with US-made equivalents to bring the Benelli M4 into 922(r) compliance for configurations that include aftermarket components like pistol grips, collapsible stocks, and magazine tube extensions. Common 922(r) compliance parts include US-made followers, magazine tube extensions, trigger groups, hammers, sears, and disconnectors from FFT and other domestic manufacturers.
