ProMag COL26 10rd AR-15 Magazine 223/5.56 Desert Tan Polymer

The ProMag COL26 delivers reliable feeding and durability for AR-15 and M16 platforms in a compact 10-round configuration. This desert tan magazine meets compliance requirements while maintaining the performance standards demanded by competitive shooters and law enforcement professionals.

What Makes This Different

Constructed from DuPont Zytel polymer, the COL26 resists impact damage and environmental stress that can compromise feeding reliability in standard magazines. The reduced 10-round capacity provides enhanced maneuverability in tight spaces while meeting state capacity restrictions. Anti-tilt followers and heat-treated springs ensure consistent cartridge presentation across thousands of loading cycles.

Key Features

• 10-round capacity for 223 Remington and 5.56x45mm NATO cartridges
• DuPont Zytel polymer construction resists cracking and UV degradation
• Desert tan finish matches FDE and earth-tone rifle systems
• Anti-tilt follower prevents jamming and double-feeds
• Heat-treated chrome silicon spring maintains tension over extended use
• Standard STANAG 4179 interface fits all AR-15/M16 pattern rifles
• Removable floor plate allows complete disassembly for maintenance

Field testing demonstrates consistent feeding across various ammunition weights from 55-grain FMJ to 77-grain match bullets. The polymer body withstands temperature extremes from -20°F to 140°F without dimensional changes that affect function. Competition shooters report smooth reloads and positive seating in magwells across multiple rifle manufacturers. The reduced profile works well in prone positions and confined shooting positions where full-capacity magazines create clearance issues.
