Carlson's 04504 +10 Magazine Extension Remington 870/1100/11-87/V3

The Carlson's Choke Tubes 04504 Magazine Extension increases capacity by 10 rounds for multiple Remington shotgun platforms. This extension transforms standard hunting shotguns into high-capacity tactical firearms suitable for competition, law enforcement, and home defense applications.

What Makes This Different

Unlike universal extensions that require modification, the 04504 provides direct compatibility across five Remington platforms without gunsmithing. The blued steel construction matches factory finishes while maintaining the structural integrity needed for extended magazine tubes. Most aftermarket extensions add only 2-3 rounds, but this model delivers a full 10-round capacity increase.

Key Features

• +10 round capacity increase for enhanced firepower
• Blued steel construction matches Remington factory finish
• Compatible with 870, 1100, 11-87, Versa Max, and V3 models
• Spring and follower included for complete installation
• Threaded attachment system ensures secure mounting
• 12 gauge chamber specification for reliable feeding
• Professional-grade materials resist corrosion and wear

Field testing demonstrates consistent cycling across various shell lengths and loads. Competition shooters benefit from reduced reload frequency during 3-gun matches, while tactical applications gain sustained fire capability. The extension maintains reliable function with both light target loads and heavy waterfowl ammunition. Weather-resistant blued finish protects against moisture and field conditions.
