When it comes to dimensions and the caliber, this is what comes to most people's minds when you say AR15. This Cmmg Resolute Mk4 5.56x45mm Nato 16.1" Rifle (55AC780) comes chambered in 5.56x45mm, one of the most prolific calibers in the world, and for good reason. 5.56, and its counterpart .223 Rem, have seen service with militaries, hunters, and recreational shooters for decades.
If you're after a particular look or have a certain AR accessory that fits you best then don't worry, this 5.56 Resolute is built on Cmmg's Mk4 platform and accepts virtually any and all AR15 accessories.
Fitted with the suite of ZEROED parts and accessories as well as our legendary RIPSTOCK, the Resolute is the rifle that’s never out of place. The new EML 15 handguard brings style to the next level. M-LOK attachment slots are found where expected at the 3, 6, and 9 o'clock positions as well as on top at 12 o'clock with the omission of a full-length Picatinny section found on our previous handguard. This reduces weight while the additional M-LOK section still gives shooters a place to mount those must have accessories.
The AR15 platform is well known for its capability for customization but picking the right parts doesn't have to be a nightmare of homework. Cmmg's ZEROED parts and accessories are made here in the USA with quality and attention to detail that is second to none and each RESOLUTE comes equipped with a slew of ZEROED parts standard, including: ZEROED Pistol Grip, ZEROED Trigger Guard, ZEROED 60 degrees /90 degrees Ambi Safety, ZEROED AR15 Ambi Charging Handle, ZEROED Ambi Mag Catch, ZEROED Extended Mag Release Button, ZEROED AR15 Bolt Catch, ZEROED AR15 Polymer Dust Cover, ZEROED Muzzle Brake 5.56mm.
