Magazines

The C Products, LLC 20 round and 30 round AR magazines are constructed using Aluminum Alloy type 6061, spec AMS-QQ-A-250/11. They are heat-treated to a temperature of 985 degrees and then rapidly quench cooled. This achieves a T6 temper and hardness.

Each magazine is hard coat anodized per MIL-A-8625, Type III, Class 1, to a film thickness of .001 +or- .0002 and finished with a D-dry film lubricant per MIL-L-46010 to a thickness of .0002-.0005.

The magazines are assembled using a MIL-STD Green Follower with the option of two springs:
1. Standard 17-7 Stainless steel spring [Heat treated and passivated]
2. Enhanced Chrome Silicon Spring

The Standard 17-7 Stainless steel spring has been used for years and proven to be reliable, however, exhibits the characteristic of weakening over time and left in stress, i.e. in a loaded magazine.

The enhanced Chrome Silicone spring, originally used in Anti-aircraft weapons for their resilience, is a spring that will take an initial set and maintain it these properties, not showing any weakening as in the stainless steel. While a light coating of oxidation may occur on the outside surface of the spring, it does not degrade the quality or performance of the spring in any way.
