HK 235642S Magazine HK416/MR556 5.56NATO 10RD Steel Black

The HK 235642S magazine delivers restricted-capacity compliance for HK416 and MR556 platforms without sacrificing the reliability that defines Heckler & Koch feeding systems. This 10-round steel magazine maintains full compatibility with standard HK rifle systems while meeting jurisdictional capacity restrictions.

What Makes This Different

Unlike polymer alternatives, the steel construction provides superior dimensional stability under extreme temperature variations and extended storage periods. The magazine incorporates HK's proven follower geometry and spring tension calibrated specifically for 5.56x45mm NATO cartridges. Internal components resist deformation even when loaded to capacity for extended periods, ensuring consistent feeding geometry that polymer magazines cannot match.

Key Features

• 10-round capacity meets restricted jurisdiction requirements
• Steel construction provides superior durability and dimensional stability
• Compatible with HK416, MR556, and MR762A1 rifle platforms
• Anti-tilt follower prevents binding and double-feeds
• Corrosion-resistant black finish withstands environmental exposure
• Standard HK magazine release compatibility
• Witness holes allow visual round count verification

Field performance demonstrates consistent feeding across temperature ranges from -40°F to 140°F, critical for duty applications where environmental conditions vary dramatically. The steel body maintains structural integrity under impact stress that would crack polymer housings. Competition shooters appreciate the positive seating and reliable ejection characteristics during rapid magazine changes.
