The PRO2A 12.5" 6.5 Grendel Carbine Length Non-Reciprocating (NR) Side Charging Upper Kit with Flash Can delivers a hard-hitting, intermediate-range ballistic option optimized into a streamlined, high-ergonomics package. This comprehensive rifle completion package upgrades traditional top charging handles to a rigid billet side-charging design, paired with a blast-forwarding linear muzzle device that safely sits recessed inside a premium free-float M-LOK handguard. Shipped with a full lower completion parts pack and an adjustable stock assembly, it removes all parts guesswork for builders looking to round out a stripped lower receiver into an optimized 6.5 Grendel hunting or sporting platform.

This premium 12.5-inch 6.5 Grendel kit bridges the structural gap between compact build profiles and full-bore downrange velocity thresholds. By merging a stationary left-side charging mechanical system with a blast-diverting linear muzzle device, it addresses the harsh muzzle blast and awkward ergonomics common to mid-length large cartridge builds. Packed securely with a high-durability nitrided side-charging carrier group, a full lower receiver completion layout, and a rugged matching stock assembly, it supplies home builders with a streamlined, field-ready firearm system built for unparalleled modularity and tactical longevity.
