The Faxon ARAK-21 Complete Upper (URSSB556SSMB) in 5.56 NATO is a rugged, innovative upper receiver system that redefines the traditional AR platform with enhanced durability, reliability, and versatility. Built around a long-stroke gas piston operating system, the ARAK-21 runs cleaner and cooler than standard direct impingement designs, reducing fouling and improving performance in demanding conditions.
Engineered as a self-contained system, the ARAK-21 features a monolithic aluminum upper receiver with an integrated top Picatinny rail, providing a stable platform for optics and accessories. The side-charging, non-reciprocating handle allows for easy manipulation without breaking your shooting position, while the robust bolt carrier system is designed to withstand heavy use and high round counts.
The free-floating barrel design enhances accuracy potential, and the adjustable gas system allows shooters to fine-tune performance for different ammunition types or suppressed shooting. Its quick-change barrel capability adds another level of flexibility, making it easy to adapt the platform to different configurations.
Finished in a durable coating for long-term wear resistance, the ARAK-21 combines modern engineering with battle-ready reliability. Proudly made in the USA, it is an excellent choice for shooters looking to upgrade their AR platform with a piston-driven system that delivers superior performance, modularity, and strength.
