About the Manufacturer
Ammunition Storage Components
ASC, based in Connecticut, was founded in February 2011 by Jonathan Scalise. To ensure success and quality production, Jonathan assembled a management team for ASC that had been active in the magazine manufacturing business in various capacities for approximately ten years. With the ASC team's extensive knowledge in the firearms industry and relying on years of experience in the metal stamping, heat treat and finishing industries, ASC has become the approved supplier of many of the most well-known firearms manufacturers and distributors in the nation. ASC's product lines have continuously proven to be of the highest quality and diversity offered by a single manufacturer. 

Who We Are
ASC's product line encompasses the entire AR-15 rifle platform. We manufacture and supply most caliber magazines currently being used on the AR platform. We know of no other manufacturer, foreign or domestic, that has this level of focus and versatility on the AR.

Our dedication to the AR-15 makes ASC the supplier of choice for most O.E.M. manufacturers. Having a proven magazine manufacturer who supports their platforms with high quality products, gun manufacturers have the option of expanding their rifle platforms. Distinct from our competitors, we offer rifle magazines in aluminum or stainless steel, along with several options for engineered coatings. 

We Are Innovative
Through the use of cutting edge robotic manufacturing technology, we are able to consistently achieve a quality part at a competitive price. Our commitment to innovation in the firearm industry has led to product lines available in aluminum or stainless steel; a thinner, more versatile metal for magazine manufacturing.

Our Engineering team is always ready to improve or develop the next advancement in product requirements, maintaining our cutting edge technology. Because of our dedication to the firearms industry, we are continuously looking to build a better product and expand the spectrum of offerings to the everyday shooter. 

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.
