The Aero Precision M5 Complete Upper in 6.5 Creedmoor is designed to maximize the cartridge's long-range potential while maintaining the familiar AR-10 platform ergonomics. The assembly features a forged 7075-T6 aluminum receiver with a precision-machined barrel extension and M4 feed ramps. The upper typically comes with a 22 or 24" stainless steel barrel with a 1:8 twist rate, optimized specifically for stabilizing the heavier 6.5 Creedmoor projectiles. The match-grade barrel incorporates 5R rifling to reduce bullet deformation and enhance accuracy potential. The complete assembly includes Aero's enhanced M-LOK handguard system, providing a rigid platform for accessories while promoting barrel harmonics. The upper features their enhanced bolt carrier group specifically headspaced for 6.5 Creedmoor, with a properly staked gas key and premium extractor spring for reliable operation. The rifle-length gas system is tuned for the 6.5 Creedmoor cartridge, providing smooth cycling and reduced felt recoil. Additional features include a threaded muzzle (typically 5/8x24), integrated brass deflector, dust cover, and forward assist. The entire assembly is finished in hard-coat anodizing for durability, with typical weight ranging from 5-6 pounds depending on specific configuration and barrel length.
