ODA Green

Used on: magazine extensions, magwells

ODA's (Operational Detachment Alpha) are the boots on the ground operational teams of a Special Forces Group. This color began as a special run for a deployed ODA. In continued support we have decided to continue the color as a standard offering and donate a portion of the proceeds to The Green Beret Foundation. Finish is anodized in green.

QPQ Nitrocarburizing Surface Treatment

Used on: magazines, barrels, slides

QPQ Nitrocarburizing is a type of surface treatment used to enhance the durability and corrosion resistance of metal parts. The process involves heating the metal in a controlled environment, where nitrogen and carbon are introduced to the surface of the metal. This forms a thin layer of a hard compound called "nitrides," which increase the surface hardness of the metal.

During the QPQ Nitrocarburizing process, the metal is immersed in a special salt bath and heated to high temperatures. The salt bath contains a mixture of chemicals that release nitrogen and carbon, which penetrate the surface of the metal. The process is carefully controlled to ensure that the nitrogen and carbon penetrate to a specific depth, creating a uniform layer of nitrides on the metal's surface.

The resulting nitride layer provides many benefits to the metal parts, including increased hardness, wear resistance, and corrosion resistance. This treatment helps to increase the lifespan and durability of metal parts, making them more reliable and long-lasting.

Any “scuffing” you see in the surface finish is completely normal, and will not affect the durability or corrosion resistance of the steel.

Electroless Nickel Plating

Used on: magazines

Silver electroless plating offers superior electrical conductivity and corrosion protection with excellent deposit uniformity and adhesion properties. This bright, reflective finish provides outstanding solderability and contact resistance while maintaining the consistent thickness and coverage that electroless plating processes are known for. Black electroless nickel plating provides these same exceptional deposit properties - including lubricity, hardness, and corrosion resistance - but with a fully conductive and uniform black surface finish that combines superior performance with an attractive dark appearance.
