About Fits Mossberg 500
Mossberg 500 Stocks
Mossberg 500 stocks are replacement and aftermarket buttstocks, forends, and grips for the Mossberg 500 pump-action shotgun platform, available in wood, synthetic, tactical, adjustable, and pistol grip configurations. The Mossberg 500 stock mounts to the rear of the receiver with a single through-bolt that threads into the receiver tang. Mossberg 500 stocks are compatible with the Mossberg 590, 590A1, Maverick 88, and 590 Shockwave platforms, because all 500-series shotguns share the same receiver stock bolt pattern. Mossberg 500 stock options include factory Original Equipment Manufacturer (OEM) replacement stocks from O.F. Mossberg & Sons, premium walnut stocks from WOOX, and aftermarket tactical stocks from Magpul, Hogue, Advanced Technology International (ATI), Choate, and Mesa Tactical. TactaBlue carries Mossberg 500 stocks alongside complete Mossberg kits including FLEX conversion kits, tactical stock adapter kits, rail kits, and furniture sets for the full Mossberg 500 series.
Mossberg 500 Stock Types
Wood Stocks
Wood Mossberg 500 stocks use American walnut with a satin polyurethane or hand-rubbed oil finish in traditional straight-grip and Monte Carlo comb profiles. The Mossberg OEM Shotgun Stock - Wood, 12 Gauge (#14480WS, $85.00) and Shotgun Stock - Wood - 20 Gauge (#13612WS, $85.00) replace the factory synthetic stock with a walnut buttstock. The Shotgun Stock - Wood w/ Dual Comb - 12 Gauge (#95059, $98.00) includes a removable cheek riser that adjusts the comb height for use with iron sights (low comb) or mounted optics (high comb). The Mossberg Retrograde Walnut Stock and Forend Kit (#95377, $265.00) provides a matched walnut buttstock and corncob-style forend. Wood Mossberg Forearms are available in 12 Gauge (#13483WS, $75.00, fits 6.75-inch / 171.5 mm action slide) and 20 Gauge (#14472WS, $75.00).
Synthetic Stocks
Synthetic Mossberg 500 stocks use glass-filled polymer construction that resists moisture, temperature changes, and impact damage without the maintenance requirements of wood stocks. The Mossberg OEM Shotgun Stock - Synthetic - 12 Gauge (#95030, $81.00) and Shotgun Stock - Synthetic - 20 Gauge (#14672, $78.40) are direct factory replacement buttstocks. The Shotgun Stock - Synthetic, +4 Storage - 12 Gauge (#95035, $147.00) includes a hollow buttstock compartment that holds 4 spare shotshells inside the stock body. The Mossberg Shotgun Stock - Compact LOP - .410 Bore (#95025, $88.00) uses a shorter 12-inch (304.8 mm) Length of Pull (LOP) for youth and small-stature shooters. Synthetic forends are available in standard (#95051, $41.00, fits 7.75-inch / 196.9 mm action slide) and tri-rail configurations (#95031, $48.00) with Picatinny accessory rails on 3 sides.
Tactical Stocks
Tactical Mossberg 500 stocks convert the factory buttstock to an AR-style telescoping configuration with a pistol grip, adjustable LOP, and buffer tube for home defense and tactical applications. The Mossberg 6-Position Adjustable Stock with Aluminum Buffer Tube, 12 Gauge (#17827, $119.99 sale / $179.35 regular) replaces the factory stock with a 6-position collapsible stock and mil-spec buffer tube. Mesa Tactical, Magpul, and ATI produce aftermarket tactical stock adapter kits that mount an AR-pattern buffer tube to the Mossberg 500 receiver. Tactical stocks reduce LOP from the factory 14 inches (355.6 mm) to as short as 10.5 inches (266.7 mm) in the collapsed position, allowing shooters to adjust fit for body armor, heavy clothing, and multiple user body sizes.
Pistol Grip Stocks
Pistol grip Mossberg 500 stocks replace the factory buttstock with a standalone pistol grip that eliminates the shoulder stock for a compact overall length. The Mossberg Pistol Grip Kit - 12 Gauge (#95000, $45.00) fits the Mossberg 500, 590, 590A1, 535, 835, and Maverick 88. The Choate 930/935 Pistol Grip Stock (#19002, $74.00) provides a full pistol grip stock for the Mossberg 930 and 935 semi-automatic platforms. Pistol grip stocks reduce the Mossberg 500 overall length by 8 to 10 inches (203.2 to 254.0 mm) but eliminate shoulder contact for recoil management.
Mossberg 500 Stock Compatibility
Cross-Model Compatibility
Mossberg 500 stocks fit 5 Mossberg pump-action platforms that share the same receiver stock bolt pattern: the Mossberg 500, Mossberg 590, Mossberg 590A1, Maverick 88, and Mossberg 590 Shockwave. The Mossberg 500 stock bolt is a 3/8-inch diameter bolt that threads into the receiver tang from inside the stock. The Maverick 88 uses a cross-bolt safety on the trigger guard instead of the Mossberg 500 top-mounted tang safety, but the stock mounting system is identical. The Mossberg 590A1 uses the same stock bolt as the 500 and 590. The Mossberg 505 and 510 compact youth models use a scaled-down receiver that does not accept standard Mossberg 500 stocks.
Mossberg 930 Stock Differences
Mossberg 930 and 935 semi-automatic shotgun stocks are not interchangeable with Mossberg 500 series pump-action stocks. The Mossberg 930 uses a different stock bolt interface and receiver geometry than the 500 series. Mossberg 930-specific stocks include the 930/935 Stock, Synthetic, 12 Gauge (#16759, $68.00), 930/935 Monte Carlo Stock - Synthetic (#17635, $75.00), and 930/935 Forearm, Synthetic, 12 Gauge (#16773, $44.00).
Mossberg 500 Stock Dimensions and Fit
Length of Pull
Mossberg 500 stock LOP ranges from 10.5 inches (266.7 mm) in a collapsed tactical stock to 14.25 inches (361.9 mm) in the longest FLEX Standard Stock configuration. The factory Mossberg 500 synthetic stock has a 14-inch (355.6 mm) LOP. LOP is measured from the center of the trigger face to the center of the recoil pad surface. Use a shorter LOP of 12 to 13 inches (304.8 to 330.2 mm) for shooters under 5 feet 6 inches (167.6 cm) in height, youth shooters, and shooters wearing body armor or heavy outerwear. Use a longer LOP of 13.5 to 14.25 inches (342.9 to 361.9 mm) for shooters over 5 feet 10 inches (177.8 cm) with a longer arm reach.
Stock Bolt and Hardware
The Mossberg 500 stock bolt threads into the receiver tang at a torque specification of 20 foot-pounds (ft-lb / 27.1 Newton-meters). The stock bolt passes through the buttstock from the rear, through a flat washer and lock washer, and into the receiver tang threads. Access the stock bolt by removing the recoil pad — the Mossberg factory recoil pad attaches with 2 Phillips-head screws. Use a solid-shank Phillips screwdriver to remove the recoil pad screws, because interchangeable bit drivers can embed in the rubber pad material. The stock bolt requires a long-reach socket or ratchet extension to reach through the stock channel.
Mossberg 500 Recoil Pads
Mossberg 500 recoil pads attach to the rear face of the buttstock and absorb recoil energy during firing to reduce felt recoil at the shooter's shoulder. The Mossberg Recoil Pad for Synthetic Stock (#16080, $12.21) is a direct OEM replacement. The Checkered Recoil Pad for Synthetic Stock (#16776, $15.10) adds a textured surface for consistent shoulder placement. The Recoil Pad for Wood Stocks (#2090, $12.75) requires fitting — sand or trim the pad to match the wood stock profile. LimbSaver recoil pads are compatible with Mossberg 500 stocks and use Navcom technology to absorb vibration across a broader frequency range than standard rubber pads.
Mossberg 500 Forends
Mossberg 500 forends (also called forearms or pump handles) mount to the action slide bars that cycle the pump action and are available in synthetic, wood, M-LOK, and Picatinny tri-rail configurations. Mossberg 500 forends come in 2 action slide lengths: 6.75 inches (171.5 mm) for older models and 7.75 inches (196.9 mm) for current-production models. Verify the action slide length before ordering a replacement forend — the forend will not fit, if the action slide length does not match. The WOOX Gladiatore M-LOK forend ($169.00) replaces the factory forend with an American walnut pump handle featuring M-LOK accessory slots on both sides and checkered grip panels. The Mossberg Tri-Rail Synthetic Forend (#95031, $48.00) adds Picatinny rails on 3 sides for mounting weapon lights, lasers, and vertical foregrips.
Mossberg 500 Stock Installation
Stock Removal
To remove a Mossberg 500 stock, unload the shotgun, remove the 2 recoil pad screws with a Phillips screwdriver, remove the recoil pad, and unthread the stock bolt with a long-reach socket or ratchet extension. Pull the stock rearward off the receiver tang. The action spring and action spring follower sit inside the stock channel on some Mossberg 500 models — keep the spring and follower in order during removal for correct reassembly.
Stock Installation
To install a new Mossberg 500 stock, slide the new stock onto the receiver tang, insert the stock bolt with a flat washer and lock washer, and torque the bolt to 20 ft-lb (27.1 Nm). Verify the stock seats flush against the receiver face with no gap between the stock and receiver. Reinstall the recoil pad and tighten the recoil pad screws. Cycle the pump action 5 to 10 times after installation to verify the stock does not interfere with the action slide bars, safety tang, or trigger group operation.
Mossberg 500 History and Production
O.F. Mossberg & Sons designed the Mossberg 500 in 1961 as a modular pump-action shotgun with interchangeable barrels, and the 500 series has exceeded 11 million units manufactured through 2021. The Mossberg 500 was the first shotgun to pass the US military qualification trial of 3,000 rounds of 12-gauge high-power buckshot without failure. Military-specification Mossberg 590A1 shotguns use a heavier barrel profile and aluminum trigger group housing. The Mossberg 500 is available in 12-gauge, 20-gauge, 28-gauge, 10-gauge, and .410 bore chamberings. The 12-gauge Mossberg 500 is the most common configuration for hunting, home defense, law enforcement, and competition use.
