Ruger AR-556 MPR | .223 Rem/5.56 | 18.06 in | 10 Rd

The Ruger AR-556 Multi-Purpose Rifle (MPR) pairs an 18.06″ Proof Research carbon fiber barrel with Ruger-appointed features such as a Magpul PRS Lite stock and Magpul MOE-K2 grip. It is chambered for .223 Rem/5.56 NATO and finished in a Kryptek Highlander hydro-dip for a camo appearance. The rifle is configured with a 10-round detachable magazine and a 1/2×28 threaded muzzle for accessories. For an optic under $1,000 that balances close and mid-range capability, consider a Vortex Viper PST 1-6×24 or a similar 1-6x low-power variable optic.
