ar-556

The SR-556 is a semiautomatic AR-15 style rifle manufactured by U.S. firearms company Sturm, Ruger & Co. The rifle was introduced in 2009 in 223 Remington/5.56×45mm NATO and as a .308 Winchester AR-10 variant in 2013, the SR-762. It is one of several 21st-century AR-15 rifles to use gas piston operation (SR-556). In January 2016 Ruger discontinued all SR-556 rifles and introduced a new takedown variant with a lightweight KeyMod handguard.

    Scope & Mount Recommendation for an AR-15?

    Howdy all. I am thinking of adding a scope to my AR-556. I do pretty much all of my shooting with iron sights, so it has been a while since I've invested in optics. As such, I'd value some input on the topic. As for the "what for" question: Target shooting and plinking. If/when my schedule...
