California, among other restrictive states, passed a series of laws designed to restrict the ability of law-abiding gun owners to effectively reload their AR-style sporting rifles. This not only tramples on the rights of law-abiding citizens, it also prevents innocent civilians from reloading their guns quickly in the face of an attacker, possibly costing lives. To combat this, Mean Arms developed its MA-Loader, the first-ever loading device designed to reload AR-style .308s and AR-15s from the ejection port.

The Mean Arms MA-Loader doesn't require any modifications to a standard AR-15 or AR-style .308 rifle to function. The company offers an MA Feed Ramp designed to streamline the loading process, but it is not required to use the loader. These mag loaders will load 10 rounds of 7.62 NATO or 5.56 NATO quickly and easily, allowing honest gun owners to get their rifles back into action quickly and easily.

A Mean Arms MA-Loader designed for use in the AR-15 will function in any mil-spec AR-15 rifle. The MA-Loader designed for use with AR-style .308 rifles functions with most short-action AR designs on the market, including the DPMS LR-308 and the GII.
