Aero Precision’s Reputation for Quality

Since its inception in 1994 in Tacoma, Washington, Aero Precision has drawn on its aerospace manufacturing roots to produce components known for their precision and reliability. Starting with parts for major manufacturers, a role they continue to uphold, the company expanded to brand its own products, gaining recognition for American-made components at competitive prices. Their commitment to using 100% U.S.-sourced materials and advanced machining ensures tolerances tighter than many competitors, even within mil-spec standards. Operating from a large facility in Lakewood, Washington, and strengthened by their 2014 acquisition of Ballistic Advantage, Aero Precision serves both individual builders and OEMs with consistent quality.

The M5 platform reflects this legacy, offering a robust AR-10 design that supports larger calibers like .308 Winchester and 6.5 Creedmoor. With complete uppers, lowers, and receiver sets, the M5 provides builders with versatile options for crafting rifles that excel in performance and customization, making it a compelling choice for AR10 builds.

The M5 Platform: A Foundation for Big-Bore Performance

The M5 is Aero Precision’s AR-10 platform, designed to handle the increased power and recoil of larger calibers like .308 Winchester and 6.5 Creedmoor. Unlike the smaller AR-15, the M5 accommodates full-size rifle cartridges, offering enhanced ballistics for long-range shooting, hunting, or tactical applications. The platform’s DPMS Gen 1 compatibility ensures it works with a wide range of aftermarket parts, allowing builders to customize their rifles with barrels, BCGs, and handguards.
