Timber designed the Greyman series with the gunfighter in mind. The Greyman Lower Parts Kit has improved on previous products by adding improved features such as cross-hatch texturing, smoothed and rounded edges, and making more parts out of billet aluminum, exceeding all mil-spec standards for a better product. CNC-machined billet aluminum construction maximizes strength and stability, while corrosion-resistant finishes protect against rust, dirt, and debris for added reliability. This Lower Parts Kit does not however include a trigger guard, trigger, or pistol grip. This allows the user to choose the specific parts and furniture that they prefer.
