## Description

The CMMG Resolute MK4 in 6.5 Grendel is a direct-impingement AR-platform rifle with a 16.1-inch barrel and a Coyote Tan Cerakote finish. The 6.5 Grendel cartridge gives it a meaningful ballistic step up from 5.56, better long-range performance and more energy on target, while still fitting in a standard AR lower with a magazine swap.

### Key Specifications
- **Model:** Resolute MK4
- **Manufacturer:** CMMG
- **Caliber:** 6.5 Grendel
- **Barrel Length:** 16.1 inches
- **Capacity:** 10 rounds
- **Weight:** 6.4 lbs
- **Finish Color:** Coyote Tan Cerakote
- **Condition:** New in Box

### Detailed Features

- **Direct Impingement System**: Standard AR gas operation for reliable cycling and reduced recoil relative to the cartridge's power level.

- **Barrel**: 16.1-inch, 1:8 twist rate. The 1:8 twist stabilizes heavier 6.5 Grendel projectiles well for target and hunting use.

- **CMMG ZEROED Muzzle Brake**: Reduces muzzle rise and recoil, which helps with follow-up shots.

- **Receivers**: Billet 6061 T6 aluminum upper, forged 7075 T6 aluminum lower. Durable and light.

- **RipStock Adjustable Stock**: Length-of-pull adjustment to fit different shooters.

### Usage

This rifle suits precision target shooting, hunting medium-sized game, and general range use. The 6.5 Grendel's flat trajectory and retained energy past 500 yards make it more capable at distance than .223/5.56, though at 6.4 lbs the rifle stays light enough to carry in the field. Shooters transitioning from .223 will notice the additional recoil is modest. The direct-impingement system and muzzle brake keep it controlled.

## What Reviewers Say

*Quoted verbatim from YouTube reviews. Each link opens the video at the moment quoted.*

> At a hundred yards any time you're under three quarter MOA with an AR that's a really good number not a whole lot of guns or guys can hold that consistently.

> Every 810 20 rounds or so I would have an extraction problem spent shell casings stove-piped against the bolt in the ejection port and then a live round stripped off of the magazine.

> Confirmed with CMM G for this rifle there should only be one I know some guys do run to I put it back together with one o ring behind the extractor and it's been running 100% since.

> If you had to pick one AR you could do a lot worse than this so it's been a lot of fun and I've really been glad that I got this particular ride.

## What Customers Say

*AI-generated insights from customer reviews*

Owners of the CMMG Resolute MK4 6.5 Grendel in Coyote Tan generally rate it well. Build quality and the Coyote Tan finish are frequently mentioned positives. CMMG's construction is consistent enough that reliability complaints are rare among owners. The 6.5 Grendel cartridge's accuracy and effectiveness for both target work and hunting draw direct praise, and the platform's modularity means accessories and customization are straightforward.

On the critical side, price is a regular discussion point. Some shooters feel it sits high compared to competing 6.5 Grendel options. Parts and accessories for the 6.5 Grendel are less available than for .223 or .308, which a few users flag as an inconvenience. Shooters coming from common calibers also note an adjustment period with the Grendel's ballistics, though this is a cartridge characteristic rather than a rifle fault.

Overall the reception is positive, with performance and aesthetics as the main draws and price as the main reservation.
