Every one of their rifles is made with real attention to detail and the highest quality parts. Continuing to evolve and offer new technologies and features, they offer some of the best AR models available today.

Since they manufacture AR-style rifles, it makes sense that the most common option they offer is the 5.56 model. With almost 20 different configurations available, this option gives you the classic AR performance that you expect from a battle rifle. Options on these rifles vary quite significantly, but one of the most popular models is the Mk4LEM. This uses a 16” barrel topped off with an A2 compensator to give shooters more muzzle control and less felt recoil. It uses a forged upper made from 7075-T6 aluminum and a mil-spec lower. It relies on a mil-spec style trigger to provide smooth operation and comes with a fixed front iron sight and flip-up rear sights, as well as a 6-position adjustable stock.

Other AR-15 models chambered in 5.56 come with barrels ranging from 14.5” in length with a 1:7 twist to 24” with a 1:8 twist. Some use a standard M4 style handguard and others offer a KeyMod system to give you ease when attaching accessories. Some of the options include Magpul parts and others rely on CMMG specific features. Depending on what type of rifle you are looking for, you can find a 5.56 NATO model that works.

If you are looking for a 300 BLK, you can find similar options, but they also offer some built more for cover operations. The Mk4PDW 300BLK is the perfect example of this. It uses an 8” barrel with a 1:7 twist and is topped with an A2 compensator threaded for suppressor attachment. It comes with a KeyMod system and uses a Magpul MOE pistol grip and carbine stock. Users can attach the optics of their choice on the top accessory rail.

After this, CMMG also has models chambered in .308 Winchester or 7.62x39mm. Both of these options offer models with longer barrel configurations and provide for a great field rifle. Finally, they offer 9mm models as well, including their rifle-style pistol Mk9PDW, 9mm.
