Lower receiver is fitted with Magpul® MOE® grip and MOE SL® collapsible buttstock on a Mil-Spec buffer tube.

Handguard is free-floated for accuracy and the slim, 15" length provides enhanced ergonomics.

Bolt is mil-spec 9310 and is machined, shot peened and proof tested for strength and durability.

The Ruger® Elite 452® AR-Trigger is a two-stage trigger that offers a smooth, crisp, 4.5 pound trigger pull. It features a full-strength hammer spring for consistent primer ignition and a lightweight hammer that enables a faster lock time for improved accuracy.

Magpul® M-LOK® accessory attachment slots along the 3:00, 6:00 and 9:00 positions with additional slots on the angled faces near the muzzle.

Ruger® muzzle brake is a radial port design that significantly reduces felt recoil and muzzle movement. The threaded barrel allows for standard muzzle accessories to be installed.

Cold hammer-forged 4140 chrome-moly steel barrel with ultra-precise rifling provides exceptional accuracy, longevity and easy cleaning. The 1:8" twist rate stabilizes bullets from 35 to 77 grains, and the 5.56 NATO chamber allows the use of both 5.56 NATO and .223 Rem. ammunition. M4 feed ramps provide improved reliability, and the matte black nitrided finish provides corrosion resistance.

Made from aerospace-grade 7075-T6 aluminum forging, the flat top upper receiver includes a forward assist, dust cover and brass deflector.

Bolt carrier and gas key have chrome-plated inside diameters to provide exceptional resistance to hot gases. The gas key is staked so that it will not loosen after extensive firing.

Rifle-length gas system provides smoother operation and reduces felt recoil.

Also includes: one, 30-round Magpul® PMAG® magazine.

The information below comes from our Gun Caliber Dictionary and is for general reference only. It does not describe the specifications of this particular item.

The 5.56X45mm NATO cartridge was designed by James Sullivan, a member of Eugene Stoner's engineering team that developed both the M16 rifle and its original cartridge. The 5.56X45mm NATO was adopted by the U.S. military in 1964 and by NATO in 1980. With bullet diameter of .224-inch, the original M193 military cartridge used a 55-grain bullet at 3250 fps; the current M855A1 cartridge, developed by FN, uses a 62.5-grain bullet at 3020 fps, offering greater range and better penetration. The civilian version of the 5.56X45mm is 223 Remington; the cartridges are dimensionally identical but military chamber dimensions and specifications for military brass are different. It is considered safe to use 223 Remington ammo in a 5.56X45MM NATO chamber, but not a good idea to use 5.56X45mm ammo in a rifle specifically chambered for the 223 Remington. Although the stopping power of .22-caliber bullets remains controversial the 5.56X45mm has served well in now multiple generations of M16 rifles. — Craig Boddington
