When it comes to dimensions and the caliber, this is what comes to most people's minds when you say AR15. This CMMG RESOLUTE 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.

Whether you're considering your first rifle or picking a new addition, a 5.56 RESOLUTE carbine is a staple for any collection.

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.

When full-size rifles are too cumbersome and pistols/SBRs don't deliver the long-range ballistic performance you need, the CMMG RESOLUTE line of carbine length rifles is the answer. Fitted with the suite of ZEROED parts and accessories as well as CMMG's 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 CMMG's previous handguard. This reduces weight while the additional M-LOK section still gives shooters a place to mount those must have accessories. With a range of choices, just pick the caliber you need for the job and let your rifle do the talking.

    Incredibly Accurate Rifle

    Posted by Rebekah Ryan on Jan 23rd 2023

    I absolutely love this rifle! It is well built and incredibly accurate. The tungsten cerakote finish looks amazing and the trigger pull is smooth. I have put hundreds of rounds through it without any malfunctions. Highly recommended!
