In a short time the Ruger AR-556 has become the direct-gas-impingement M4-style AR-15 rifle of choice for many people. It offers everything you need in a well-made reliable package with a few unique Ruger touches—for a low price. It took the company a few years, but Ruger has finally introduced a second version of its AR-556. It’s the MPR, which stands for Multi-Purpose Rifle.
