Update 6/8/2009First field test of the SR556- Sheridan, Wyoming. Ruger factory sponsored prairie dog hunt. We were privileged to attend the hunt, and an Impact employee was the first to take an animal with the SR556 rifle!
Function and reliability were 100%. The dog town we were shooting at had dogs out to 360 yards. All ranging was done using the new Ziess 8x binoculars with range and holdover function. Even with a low 10x scope, dogs were taken all the way out to 361 yards. Very impressive for any rifle!
We were shooting Hornady TAP ammo, 55g, loaded into the P-Mags that are included with each rifle. Effect on the targets was devastating. Multiple hits and complex gymnastics by the dogs were the norm.
All in all, our experience with the SR556 was beyond our expectations. The gas system gives the gun a softer recoil that a st and the chamber/bolt area was much cleaner that a gas AR. This SR556 is a keeper, and a really good value with all the good kit that is part of the base rifle.
Update Fall 2011: We have sold literally hunderds of the Ruger SR556 rifles. They are incredibly reliable and several of our customers report that even after thousands of rounds (some without cleaning) they have not experienced a single malfunction!
