American Tactical Milsport Complete Lower Features The American Tactical Milsport Lower is machined from 7075-T6 aluminum a high-strength alloy that gives the receiver the rigidity needed to stand up to repeated firing and hard use. Its anodized black finish is applied for durability resisting wear and corrosion through years of range time or duty use. As a multi-caliber compatible lower it provides a flexible foundation that builders can pair with uppers chambered in a range of AR-platform cartridges. A thumb safety offers the familiar intuitive operation that AR shooters expect from a mil-spec pattern lower. Shipping as a complete lower the Milsport includes an A2 style stock and grip already installed saving a builder the time and cost of sourcing those parts separately. At roughly 2.4 pounds it keeps the lower half of a build light without compromising the strength of the receiver. This complete ready-to-assemble configuration makes it a straightforward choice for a first build or for builders who want to swap uppers across different calibers. For anyone assembling a dependable mil-spec AR-15 from the ground up the Milsport Lower offers a solid affordable starting point.
