CMMG Resolute 100 MK4, 6mm ARC

Out of stock.

The CMMG Resolute is a carbine based on the AR15 and designed as an all-rounder - with high configurability and modularity for any application. The Resolute features a 16" barrel and a free-floating M-LOK handguard. The weapon is designed as a base firearm and offers the shooter the opportunity to personalize it according to their wishes and adapt it with accessories. Made from high-strength "aircraft grade" aluminum, the CMMG Resolute MK4 combines the classic AR15 design with modern manufacturing techniques and features.

The 6mm ARC caliber is a relatively new cartridge, introduced to the market in 2020 and developed at the request of a department of the DOD (U.S. Department of Defense). The goal of this "Advanced Rifle Cartridge" was to fire a powerful 6mm (.243) cartridge from the AR15 platform, rather than from the larger and heavier AR10 platform - thus, the fast newcomer offers nearly the same ballistic data as the proven .243 Winchester or the 6mm Creedmoor. However, with the shorter barrels typical of an AR15, the 6mm ARC has the advantage, as it was specifically designed for that purpose. The caliber is equally suitable for hunting or precision shooting, and the moderate recoil, combined with the compact and lightweight, approximately 2.9kg, CMMG Resolute MK4, is a promising combination.

Please note:
The 6mm ARC cartridge uses its own magazines! Standard AR15 magazines for the .223 do NOT fit. Since the new cartridge is similar in dimensions to the 6.5mm Grendel (e.g., both calibers use the same bolt head), 6.5mm Grendel magazines can be used. Although it achieves more than 2,000J at 100m, the cartridge is NOT suitable for large game due to its small caliber.
