Ruger's AR-556 MPR rifle has a rifle-length gas system which provides smoother operation and reduces felt recoil. The matte black oxide chrome-plated bolt carrier inside diameter and chrome-plated gas key inside diameter provides exceptional resistance to hot gases. Its lower receiver is fitted with Magpul MOE grip and a Ruger Elite 452 two-stage AR-trigger which offers a smooth, crisp, 4.5 pound trigger pull. The flattop upper receiver is made from forged aerospace-grade 7075-T6 aluminum, and includes a forward assist, dust cover and brass deflector. Its handguard is free-floating for accuracy and features Magpul M-LOK attachment slots along the 3, 6 and 9 positions. The threaded, cold hammer-forged, 4140 chrome-moly steel barrel with ultra-precise rifling provides exceptional accuracy, longevity and easy cleaning. The barrel also provides M4 feed ramps which improves operational reliability, while the matte black nitride finish provides corrosion resistance. The AR-556 MPR has a Magpul MOE SL collapsible buttstock on the Mil-Spec buffer tube and includes a 30-round Magpul PMAG.

Introduced in 1964, the 223 Remington is the civilian version of the 5.56x45mm NATO cartridge. Although very similar to the 222 Remington it has a slightly longer case and a shorter neck, giving it greater powder capacity and thus higher velocity--which was necessary to meet military penetration requirements at longer range. NOTE: 223 Remington ammunition may be safely fired in any 5.56x45mm chamber, but 5.56x45mm ammunition SHOULD NOT BE USED in a 223 chamber! Standard is a 55-grain bullet at 3240 feet per second, with lighter bullets somewhat faster and heavier bullets a bit slower. The 223 is the most popular 22 centerfire today, and possiby the most popular centerfire cartridge. Ammunition choices are legion, as are choices in firearms. The 223 is an accurate cartridge ideally suited for varmint hunting out to beyond 300 yards, and with heavy-bullet loads designed for the purpose is used effectively by many deer hunters. — Craig Boddington
