ETS Group HKMP540 40rd 9mm Magazine H&K MP5 SP5K Clear Polymer

The ETS Group HKMP540 delivers extended capacity for H&K MP5 and SP5K platforms with crystal-clear polymer construction that allows instant visual ammunition counts. This 40-round magazine transforms standard MP5 configurations into high-capacity systems for competitive shooting and tactical applications.

What Makes This Different

Unlike traditional steel magazines, the HKMP540 features translucent polymer construction that eliminates guesswork during reloads. The extended 40-round capacity doubles standard MP5 magazine capacity while maintaining the same reliable feeding geometry. Advanced polymer formulation resists impact damage and chemical exposure that can compromise metal magazines over time.

Key Features

• 40-round capacity doubles standard MP5 magazine ammunition load
• Clear polymer body provides instant visual ammunition count verification
• Drop-free design ensures reliable ejection during tactical reloads
• Compatible with H&K MP5, SP5K, MP5K, HK94, and SP89 platforms
• Impact-resistant polymer construction withstands repeated use
• Standard HK magazine catch interface requires no modifications
• Chemical-resistant materials handle cleaning solvents and lubricants

Extended range sessions benefit from reduced reload frequency, while competitive shooters gain tactical advantages through visual ammunition monitoring. The polymer construction eliminates the weight penalty typically associated with extended magazines. Cold weather performance remains consistent as polymer materials resist the brittleness that affects some metal alternatives. Training scenarios become more realistic with extended capacity that mirrors duty configurations.
