In reply to Dan Jenson. Yup, you are 100% correct there! Super disappointed with the quality myself. Even the machining is mediocre with mismatched surfaces and poor surface transitions. The worst part for me was the constant casing strikes to my 9mm Banshee Mkgs ejection port causing serious damage to the soft aluminum upper. The solution through CMMG was to add over 3ozs to the BCG. So much for the radial delay blowback! Also super disappointed the upper and lower are only 6061 and it's like they are spray painted the black finish on! The color is rubbing and chipping off everywhere!

Cmmg = poor quality materials at a premium price.

They use 4150 instead of 4140 steel for the barrel. They use softer 6061 aluminum instead of 7075 for the upper receiver. And it is NOT hard anodized. They don’t use carpenter steel for the bcg. And mine had serious wear markings on the extractor tail new out of the box. And they charge the same as a mil spec quality rifle like bcm. Cmmg is NOT mil spec. Anyone who says they are is lying. And anyone who says it doesn’t matter is misinformed. They are poor quality rifles at mil spec prices. Go to Reddit to hear how common problems are with them.

In reply to Carlos. Great comment. I was researching CMMG if whether i should buy their gun and your comment gave a much more in depth review than this article. Except based on my price comparison Ruger AR-556 MPR 350 Legend sells for $949.99 while CMMG Rifle, Resolute™ 100, Mk4, .350 Legend is at $1,049.95. I cant find any S&W M&P chambered for .350 to compare price.

The reason CMMG rifles are at that price range is because they are equal or surpass mil-spec. Their quality is top notch. And no other brand gives you mil-spec quality for the price. So CMMG accomplished what they started the company for. Then you take into consideration that some are designed for specific calibers, uses ( Carbine, Long Range, 3 Gun), and it makes sense. You won’t find a Long Range, 3 Gun, or Carbine rifle with mil-spec quality for the price. I have no complaints from CMMG. When I was young my stepfather had a CMMG M4 Carbine/5.56 NATO and it was great. It meets mil-spec material quality and durability. I’m a US Army veteran and have experience with M16 and M4 rifles. CMMG rifles meet or exceed mil-spec for a lower price. So for me the price is great. Their manufacturing materials exceed mil-spec because they use newer materials and practices not used in the 60s when the M16 was created and into the production of the M4, since then the military materials and manufacturing hasn’t changed. Some people will argue about the CMMG bolt and barrel. The CMMG bolt is 9310 steel w/ Phosphate finnish. This surpasses mil-spec Carpenter C158 steel in hardness and durability. They use it because its better material and new metallurgy. In the 60s Carpenter C158 steel was used because it was the best available at the time and cheaper to produce. As for the barrel. They now use a Chrome-moly 4140 Salt Bath Nitrided barrel. This makes the barrel more affordable while still giving you mil-pec durability. Nitrided barrels have more hardness and durability than chrome lined barrels, while also giving you better corrosion resistance, and accuracy. 4140 Nitrided barrels in AK type rifles have surpassed some cold hammer forged barrels in hardness. A 4140 Nitrided barrel will surpass 4150, 4150 CMV, 4150 Mil-Spec, chromed line barrels in durability, corrosion resistance, and accuracy. People debate and focus so much on mil-spec without understanding that metallurgy and manufacturing processes have surpassed the old mil-spec requirements which were the best in the 60s and were never changed since then even into the 60s-90s when designing the M16 Carbines aka CAR-15s, which then became the M4 Carbine.The Ruger and M&P rifles you spoke about don’t even meet mil-spec durability, and they’re more expensive. So for the price range of so many of their different mil-spec quality rifles in different configurations. No other brand can beat CMMG in price and quality. I myself will purchase a CMMG M4 Carbine in .300 BLK in the future. A 7.62mm, .30 caliber ballistics capable rifle with an M4 Carbine’s light mobility, accuracy, and durability. You can’t go wrong.
