Remington V3 12GA Shotgun Magazine Extension Kit +3/rd

The Remington V3 12GA Shotgun Magazine Extension Kit +3/rd is purpose-built for operators and sport shooters who demand extended firepower without sacrificing reliability or ergonomics. This aluminum magazine extension tube bolts directly to the factory magazine tube of your V3 platform shotgun, adding three rounds of 12-gauge capacity for a meaningful advantage in tactical entries, home defense scenarios, and competition shooting. Whether you're clearing buildings, running 3-gun matches, or securing your property, this extension kit delivers the round count demanded by modern defensive and duty applications.

Constructed from lightweight aluminum alloy, the extension tube maintains the V3's balance and pointability while withstanding repeated cycling and the stress of high-velocity loads. The +3 capacity increase is modest but critical—it extends your total payload from five to eight rounds in the magazine tube alone, reducing reload frequency during sustained-fire drills or multi-target engagements. The kit's quick-detach design allows field removal without tools, enabling shooters to transition between configurations for different mission profiles. Internal geometry is engineered to ensure reliable feeding of all 12-gauge shells, from 2.75-inch field loads to 3-inch magnum rounds, maintaining the V3's legendary durability and function.

This extension is ideal for law enforcement patrol officers, military personnel, civilian tactical shooters, and home defenders who operate Remington V3 semi-automatic shotguns. Installation is straightforward and requires no gunsmithing—simply unscrew the factory plug or cap and thread the extension tube onto the magazine tube in seconds. The extension maintains zero reliability penalties and pairs seamlessly with standard V3 stocks, furniture, and aftermarket accessories. For shooters seeking to maximize their V3's combat efficiency without altering the gun's handling characteristics, this magazine extension kit represents essential force multiplication.
