Retro Arms is a U.S.-based firearms parts manufacturer and retailer dedicated to delivering historically accurate and high-performance components for AR-platform rifles. Specializing in retro rifles and clone-correct builds, we offer a curated selection of precision-machined retro AR uppers, M16A1 upper receivers, handguards, A1-style pistol grips, and builder kits designed to replicate classic military-style configurations with unmatched authenticity.

Our offerings include parts tailored for legendary builds like the M16A1, SP1 upper, XM177, DEA carbine, M16A4 clone, and even rare configurations like the Colt LMG upper or M16 LSW. Whether you’re chasing the iconic M16A1 upper, retro M16 upper, or retro AR15 upper, we provide the components to do it right.

From early Vietnam War-era designs to Cold War-period setups, our parts reflect the exact aesthetics, dimensions, and finishes of the original firearms. You’ll find retro uppers with teardrop forward assists, triangle handguards, USGI handguards, and correct Colt handguards, along with ARS rails and even Soviet Arms long rails for specialty builds.

Our components are made in the USA and combine historically correct design with modern-day precision. Whether you’re building a display piece or a hard-use shooter, our 556 uppers, 9mm uppers, and M16 upper kits are engineered to deliver both form and function.

We also support builders with complete DIY kits, lower parts kits, and accessories like M16 LSW handguards and Colt M16A1 uppers, giving you everything you need to bring your vision to life.

At Retro Arms, we’re keeping the legacy alive—one part at a time. Whether you’re honoring the heritage of American military firearms, restoring a surplus rifle, or assembling your dream retro AR upper, we deliver the retro guns and parts you need to build with purpose, passion, and precision.
