Lower receiver only. Firearm shown for visual reference and compatibility demonstration only.
The War Hammer Armaments Complete Super Safety MP5/MP5-K Lower Platform is an all-new, in-house lower housing engineered specifically for Super Safety–equipped MP5 platforms. This lower is manufactured using a Kevlar and carbon-fiber–infused polymer, providing increased strength, durability, and dimensional stability compared to standard polymer housings.
This is not a legacy or third-party lower and is not intended to function as a generic MP5 replacement. Every aspect of the housing and internal configuration is designed to support proper selector engagement, trigger reset behavior, and long-term reliability when used with compatible hosts.
The lower features Super Safety pictogram markings on both sides with a red selector indicator, indicating correct selector orientation and Super Safety operation.
Each unit is fully assembled, inspected, test-fired, and validated in-house by War Hammer Armaments, with a focus on consistency, correct timing, and repeatable performance rather than tolerance stacking or experimental setups.
