Built around a cold hammer-forged, chrome-moly steel barrel with a 5.56 NATO chamber, it accepts both 5.56 NATO and .223 Remington ammunition. The rifle ships ready to run with an elevation-adjustable F-height A2 front sight (co-witness compatible with many optics), a six-position M4-style telescoping stock, and a 1\/2&#8243;-28 threaded muzzle with Ruger&#8217;s own flash suppressor.<\/p>\n<h3>Cold Hammer-Forged Barrel<\/h3>\n<p>The 16.1&#8243; medium-contour barrel is cold hammer forged from 4140 chrome-moly steel and finished with a matte black oxide. Cold hammer forging compresses steel around a mandrel to produce an exceptionally uniform bore with long service life. The 1:8&#8243; twist handles everything from 55 gr FMJ range loads to 77 gr match bullets.<\/p>\n<h3>Forged 7075-T6 Receivers<\/h3>\n<p>The forged 7075-T6 aluminum upper and lower receivers are hard-coat anodized to mil-spec. The upper includes forward assist, dust cover, and brass deflector, and the flat-top Picatinny rail accepts any AR-15-compatible optic.<\/p>\n<h3>Shot-Peened, Proof-Tested Bolt<\/h3>\n<p>The 9310 steel bolt is shot-peened and high-pressure proof-tested for reliability. The 8620 steel bolt carrier is chrome-lined on the inside diameter and at the gas key for corrosion resistance and easier cleaning.<\/p>\n<h3>Included Out of the Box<\/h3>\n<ul>\n<li>Ruger flash suppressor (1\/2&#8243;-28 threaded)<\/li>\n<li>Six-position M4-style collapsible stock<\/li>\n<li>A2-style F-height front sight with elevation adjustment<\/li>\n<li>Flat-top upper with Picatinny rail for optics<\/li>\n<\/ul>\n<h3>Specifications<\/h3>\n<table>\n<tbody>\n<tr>\n<th>Action<\/th>\n<td>Semi-auto, direct impingement<\/td>\n<\/tr>\n<tr>\n<th>Caliber<\/th>\n<td>5.56 NATO \/ .223 Rem<\/td>\n<\/tr>\n<tr>\n<th>Barrel length<\/th>\n<td>16.10&#8243;<\/td>\n<\/tr>\n<tr>\n<th>Barrel material<\/th>\n<td>Cold hammer forged 4140 chrome-moly steel<\/td>\n<\/tr>\n<tr>\n<th>Twist rate<\/th>\n<td>1:8&#8243; RH<\/td>\n<\/tr>\n<tr>\n<th>Muzzle thread<\/th>\n<td>1\/2&#8243;-28 (flash suppressor included)<\/td>\n<\/tr>\n<tr>\n<th>Gas system<\/th>\n<td>Carbine-length<\/td>\n<\/tr>\n<tr>\n<th>Upper \/ lower<\/th>\n<td>Forged 7075-T6 aluminum, hard-coat anodized<\/td>\n<\/tr>\n<tr>\n<th>Bolt \/ carrier<\/th>\n<td>9310 shot-peened proof-tested bolt, 8620 chrome-lined carrier<\/td>\n<\/tr>\n<tr>\n<th>Trigger<\/th>\n<td>Single-stage mil-spec<\/td>\n<\/tr>\n<tr>\n<th>Handguard<\/th>\n<td>Mil-spec drop-in carbine with heat shields<\/td>\n<\/tr>\n<tr>\n<th>Stock<\/th>\n<td>Six-position M4-style collapsible<\/td>\n<\/tr>\n<tr>\n<th>Sights<\/th>\n<td>A2 F-height front, flat-top for optics<\/td>\n<\/tr>\n<tr>\n<th>Weight<\/th>\n<td>~6.5 lb<\/td>\n<\/tr>\n<tr>\n<th>Overall length<\/th>\n<td>~32.25&#8243; \u2013 35.5&#8243;<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p>Entry-level direct-impingement AR-15 from Ruger in .223 Rem \/ 5.56 NATO.
