Ruger SR-556

THE AR PLATFORM REDEFINED. The SR-556® offers Ruger’s leg­endary rugged reli­a­bil­i­ty, and comes fac­to­ry stan­dard with a host of acces­sories that today’s shoot­ers demand. Employ­ing a patent-pend­ing, chrome-plat­ed, two-stage pis­ton dri­ven oper­at­ing sys­tem that pro­vides the user with a clean­er, cool­er run­ning, reli­able firearm that is tru­ly state-of-the-art.

The chrome-lined gas block and chrome-plat­ed pis­ton and reg­u­la­tor work togeth­er to pro­vide a smooth pow­er deliv­ery stroke to the bolt car­ri­er. The by-prod­ucts of the gas sys­tem are vent­ed out the bot­tom of the gas block, away from the bolt car­ri­er, keep­ing the action clean and free from con­t­a­m­i­nants. The end result is sig­nif­i­cant­ly improved per­for­mance over gas dri­ven rifles.
