MRK 1 Matched Receiver Set
The Towle AR MRK 1 Matched Receiver Set is the heart of the rifle. The MRK 1 Receiver was designed to be one of the most functional, durable and reliable receivers on the market. It is also one of the most complete.
Designed around the USGI standard, with enhancements developed to provide a more robust, reliable, and accurate rifle system. For the Receiver, the aluminum alloy 7075 was chosen because it is as hard as many steels while retaining the lightweight qualities of aluminum. It is then hard coat anodized (MIL-A-8625F Type III Class 2) for superior wear protection.
