RESOLUTE, MkG, .45 ACP, 16.1"
Easily one of the most iconic pistol calibers in the world with more than a century of faithful use, .45 ACP has been a go-to choice for shooters looking for a proven, heavy-hitting round. Not only does the MkG™ RESOLUTE® come chambered in this renowned caliber, but it also makes use of commonly found and trusted Glock-pattern .45 ACP magazines, and spurred the invention of our legendary Radial Delayed Blowback™ operating system years ago.
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 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. With a range of choices, just pick the caliber you need for the job and let your rifle do the talking.
MkG Radial Delayed Blowback™
Since making its debut on the original .45 ACP MkG platform in 2017, Radial Delayed Blowback has revolutionized pistol-caliber ARs across the entire CMMG lineup. As a result of meticulous engineering, Radial Delayed Blowback not only addressed some operational concerns with a traditional straight blowback system, but it also delivered pistol caliber carbines and personal-defense weapons with softer recoil impulses and lighter weight bolt carrier groups and buffer systems than straight blowback systems could deliver. Check out our CMMG Resources article & video to learn more about what sets Radial Delayed Blowback apart.
