Bringing AR innovation to everyone

History of CMMG

CMMG was founded in 2002 in Fayette, Missouri by John, Jeff, Gretchen, and Stephanie Overstreet when they decided to make an AR rifle that everyone could afford. From that moment on, they have added inventive designs and groundbreaking firearms to an otherwise overcrowded market. In 2006, they began designing parts and offering products in multiple calibers, going so far as to establish their own design and engineering team. It was because of this new team that CMMG put together a separate quality control group to ensure everything meets the highest standards set.

The first signal of a major innovation to come out of CMMG was the 22LR AR conversion kit, launched in 2010. Things changed completely in 2014 when they brought the MK47 to the market. The MK47 is an award-winning, AR-style rifle that combines the accuracy and modularity of the AR-15 with the reliability of the AK47. CMMG then moved manufacturing facility locations to Boonville, Missouri to meet their overwhelming production demands. A year later, in 2017, they launched another innovative product: the Radial Delayed Blowback.

This new operating system differed from typical direct blowback systems. Instead, the Radial Delayed Blowback system uses a bolt that is forced to rotate and unlock, slowing the bolt carrier group enough to safety. Ultimately, it means a lighter-weight rifle with noticeably less recoil. This blowback system has been used to chamber calibers that have historically been problematic on the AR15 platform, including 10mm, 45ACP, and 40 S&W. Today, CMMG is committed to continuing its mission to bring true innovation and quality to the industry.

With the introduction of the MK47, CMMG changed the AR market for the better. While the classic will always be loved, it has been improved throughout the years in order to provide gun owners with the best of the best.

This is “engineered with purpose for those who refuse to compromise on quality.” Available in 3 tiers, the Resolute 100 features a single-stage trigger, A2 compensator, 30-round mag chambered in 7.62x39 ammo, and a 16.1-inch barrel.

If you’re looking for something with even more punch, then look no further than the CMMG Endeavor 300 MK3 6.5 Creedmoor 24” 20 Rds—a 300 Series long-range rifle that performs. This is truly the best an AR has to offer with an aluminum RML M-LOK handguard, Geissele SSA Two Stage Trigger, fixed position Magpul Precision Rifle Stock, and a 24-inch barrel. The MK3 platform does accept AR10-style magazines, such as .308 Winchester and 6.5 Creedmoor. It’s beefier and heavier than the MK4 so it can handle these larger calibers with ease.
