ProMag HECA9 30rd Magazine 223/5.56 H&K 93 Black Polymer

The ProMag HECA9 magazine delivers reliable feeding for H&K 93 rifles with its 30-round capacity in 223 Remington and 5.56x45mm NATO. Built from DuPont Zytel polymer, this magazine provides consistent performance across extended shooting sessions while maintaining the lightweight characteristics shooters demand.

What Makes This Different

Unlike standard capacity magazines, the HECA9 extends shooting time between reloads with its 30-round capacity. The DuPont Zytel polymer construction offers superior chemical resistance and dimensional stability compared to basic polymer alternatives. Heat-treated steel springs maintain consistent tension through thousands of loading cycles, while the anti-tilt follower prevents feeding malfunctions that plague inferior designs.

Key Features

• 30-round capacity for 223 Remington and 5.56x45mm NATO cartridges
• DuPont Zytel polymer body resists impact, chemicals, and temperature extremes
• Heat-treated steel spring maintains consistent feeding pressure
• Anti-tilt follower design prevents double-feeds and misfeeds
• Drop-free design allows rapid magazine changes under stress
• Textured grip panels provide secure handling in wet conditions
• Compatible with H&K 93 and HK91 rifle platforms

Range testing demonstrates reliable cycling through various ammunition weights from 55-grain to 77-grain projectiles. The polymer construction withstands temperature fluctuations from -20°F to 140°F without affecting feeding reliability. Competition shooters appreciate the extended capacity for rapid-fire stages, while tactical applications benefit from reduced reload frequency during extended engagements.
