Ruger AR-556 MPR 16 Semi-Automatic Rifle .223 Rem

Ruger AR-556 MPR 16 .223 Rem

The AR-556 MPR (Multi-Purpose Rifle) is Ruger’s upgraded AR-15 for shooters who want free-floated accuracy, a better trigger, and premium furniture without stepping up to a custom build. The 16″ model pairs a free-floated cold hammer-forged barrel with a mid-length gas system — smoother than a carbine-length system — a 13.5″ M-LOK handguard, and B5 Systems Bravo stock and grip.

Ruger Elite 452 Two-Stage Trigger

The two-stage Ruger Elite 452 AR-Trigger delivers a crisp 4.5 lb break with a clean first stage and a predictable wall. It is a factory-installed upgrade over the mil-spec single-stage — you get a match-style trigger at no additional cost.

Mid-Length Gas System

A mid-length gas system runs cooler and softer than the standard carbine-length gas, reducing wear on the bolt and carrier and improving the shooting experience. Paired with the free-floated barrel, recoil is noticeably smoother and controlled.

Free-Float M-LOK Handguard

The 13.5″ “Lite” handguard is a full-length free-float tube with M-LOK slots for accessories. Because it does not touch the barrel, the barrel’s harmonics stay consistent and groups stay tight.

Ruger Radial-Port Muzzle Brake

A Ruger radial-port muzzle brake significantly reduces felt recoil and muzzle rise, keeping you on target between shots. The 1/2″-28 thread accepts most aftermarket muzzle devices or suppressors.
