FRANKFORD ARSENAL AR-15A2 LOWERS
Quality Products are produced from quality materials and processes. Frankford Arsenal is proud to carry its own line of AR-15 lower and upper receivers. All units are precision machined on four-axis CNC machines and tooling, which utilize continuous CMM dimensional monitoring via live Renishaw Probe technology during manufacturing operations for perfect centering and quality monitoring. We put additional time into machining, measuring and quality control of all manufacturing processes , reflected in the quality, uniformity and fit found in every FA product.
Hot Forging and heat treatment processes are absolutely critical to alloys performance. The hot forged 7075-T6 aluminum alloy used in all FA receivers have a highly uniform and oriented grain structure ensuring predictable strength and toughness exceeding those from other material processes including bar stock cut receivers. Forging is far superior to casting methods because it allows the elements to flow and form without segregation. Uniform element dispersion is critical to obtaining a uniform heat treatment and dimensional stability. FA uses only forgings made by Cardinal Forgings in Rochelle, Illinois. Cardinal is an ISO-9000 qualified company, with state of the art forging presses, and numerically controlled/ISO-certified heat treatment ovens. They have a proven track record as leaders in quality and uniformity and are a major manufacturer of certified mil-spec components.
FA uses only mil-spec thick hard anodizing A8625, type III. Toughness and uniform material qualities create performance uniformity. Your FA receivers will always mate together and with other 7075-T6 upper receivers in the cold of winter or heat of summer. These precision receivers can form the base platform to any number of possible upper receiver configurations, servicing the full spectrum of demands from delivering toughness and reliability to holding the sub MOA accuracy required by the modern sportsman.
