I have been concerned about the accuracy of my Ruger 556, so, after trying better ammo, I sent a request to Ruger asking if they could help. Below is the response I received:

Comment / question:
On July 26, 2010, I purchased a Ruger SR-556 at State Line Gun Shop in Mason, NH. The gun has never shot what I consider to be small enough groups. Most recently I shot a series of 10 shot groups with Black Hills 68 Grain Match ammunition and there were 2 targets at 100 yards and 2 targets at 50 yards. The 100 yard groups were 3 1/2 inches and the 50 yard groups are 1 1/2 inches. Can you do anything to help improve accuracy?
Response:
The factory specifications for this model is a 5 shot group, 2" at 50 yards.
