Why C Products Defense
Our goal is to manufacture the best-designed, highest quality, 100% reliable magazines that work the first time, every time, because a firearm is only as good as its magazine.

Quality is the number one priority at C Products Defense. For each process stamping, welding, heat treating, coating and assembly strict quality checks are in place from the initial manufacturing process all the way through testing, packaging and delivery of our final product to you.

We have the most reliable and durable magazine made today in any caliber for the M16/M4 AR platform, as well as for pistol and bolt action rifles. Our stainless steel magazines, in combination with our new "snap-on" anti-tilt follower, are the clear choice. We also offer the same "snap-on" anti-tilt follower in our aluminum magazines.

About the 5.56X45mm NATO Cartridge
The 5.56 45mm NATO (official NATO nomenclature 5.56 NATO) is an intermediate cartridge developed in the United States and originally chambered in the M16 rifle. Under STANAG 4172, it is a standard cartridge for NATO forces as well as many non-NATO countries. It is derived from, but is not identical to, the .223 Remington cartridge.

During the late 1950s, ArmaLite and other U.S. firearm designers started their individual Small Caliber/High Velocity (SCHV) assault rifle experiments using the commercial .222 Remington cartridge. When it became clear that there was not enough powder capacity to meet U.S. Continental Army Command's (CONARC) velocity and penetration requirements, ArmaLite contacted Remington to create a similar cartridge with a longer case body and shorter neck. This became the .222 Remington Special. At the same time, Springfield Armory's Earle Harvey had Remington create an even longer cartridge case then known as the .224 Springfield. Springfield was forced to drop out of the CONARC competition, and thus the .224 Springfield was later released as a commercial sporting cartridge known as the .222 Remington Magnum. To prevent confusion among all of the competing .222 cartridge designations, the .222 Remington Special was renamed the .223 Remington. With the U.S. military adoption of the M16 rifle in 1963, the .223 Remington was standardized as the 5.56 45mm NATO. As a commercial sporting cartridge the .223 Remington was introduced in 1964.
