Ruger SR-556E Essential #5912 5.56mm NATO/223 Rem., $1375 (Grade B+ Jan 2012)

Read Gun Tests Rating and Recommendation

The fully outfitted SR-556FB got an ‘A-’ grade back in January 2010, and in the major areas, theûEssential is a match to that gun. But we did like the SR-556FB’s quad-rail setup, supplied sights, andûoverall package better. Still, money talks, and we wouldn’t mind saving several hundred dollars forûthe 556E if we didn’t need the 556FB’s package. It all depends on what your pocketbook can stand.

To gain functionality on the smooth handguard, we would want to add some rails to the tapped holes on the front of the gun. We’d probably pick the 3-inch SR-556E TR3 Picatinny Rail #18090, above, for the sides and the 5-inch SR-556E-TR-5 Picatinny Rail #18095 for the bottom rail. Longer rails are available. All are made of black-finished aluminum and come with instructions and hardware. The custom-drilled pieces are available at www.ShopRuger.com.
In the Ruger’s piston system, gases from the barrel vent into the gas block and then against this piston, which in turn strikes an operating rod that replaces the gas tube.
The 4-position adjustable regulator can tune the rifle to ammunition.
The hidden winner in the test was the Ultramax 223 Remington 52-grain hollow points. This is a hot barrel 10-shot group fired with the Ultramax commercially remanufactured ammunition. There’s no stringing to be seen. Both the Ruger and the Adcor preferred this load over the others. It shot a 0.9- inch average group size in the Essential and a 0.7-inch average group size in the Elite.
