Features and Construction

The wrench is built around its practical function as a maintenance tool for a popular firearm platform. Its construction focuses on delivering the necessary form and material for the job.
Material and Build
The core material is 40Cr alloy steel, a chromium steel grade chosen for applications requiring a good combination of hardness and toughness. The surface receives a black spray treatment, which provides a consistent colour and a basic layer of protection against corrosion. This build is described as featuring ordinary characteristics, indicating a focus on fundamental, functional performance without specialised embellishments.

With a weight of 500 grams, the wrench has a substantive heft that can aid in handling and application of torque. The dual-purpose wrench shape is engineered to interface with specific components on AR-15 and M4 rifles, though the exact dimensions for the fastener sizes are not provided in the source data. Its design intent is to offer a tailored fit for those particular platforms.
