CMMG 28B260CSG Resolute 22 16.1" Rifle

The CMMG 28B260CSG Resolute 22 ARC rifle is a modern intermediate cartridge platform engineered for shooters demanding precision, modularity, and reliable performance across tactical and competitive applications. Built on the 22 ARC cartridge—a purpose-designed round that bridges the gap between 5.56mm and larger calibers—this rifle delivers balanced recoil management, superior energy retention at distance, and excellent accuracy potential from its 16.10-inch barrel.

The barrel is machined from 7075-T6 aluminum, a military-grade alloy selected for its strength-to-weight ratio and dimensional stability under sustained fire. Weighing 5.1 lbs, the platform remains lightweight without sacrificing rigidity—a critical factor for tactical carbines where quick target transitions and extended shooting sessions demand minimal fatigue. The 15-inch M-LOK handguard provides extensive real estate for accessory integration: lights, lasers, bipods, and forward grips mount directly without proprietary rail adapters. M-LOK's open design also reduces weight and allows unrestricted hand placement across the forend.

This configuration suits law enforcement patrol rifles, sport shooters exploring the 22 ARC cartridge, and operators needing a compact, modular platform for CQB-to-midrange work. The 16.10-inch barrel length optimizes velocity in the 22 ARC while maintaining overall length suitable for vehicle carry and confined-space operations. Competitors in the precision rifle and 3-gun sports communities have adopted the 22 ARC for its ballistic efficiency and shooter-friendly recoil impulse, making the CMMG Resolute 22 ARC an accessible entry point into the cartridge ecosystem.
