Got a chance to shoot my SR556 and M1 over the past few days. Both are EXCELLENT firearms. I only have 3 complaints about the Ruger. The firing pin retaining pin that came with it was to big and protruded from the side of the bolt carrier. About 10 minutes with a vice, hammer, and some files fixed that issue. The second complaint is that the aluminum hand guard gets hot; FAST. 60 rounds in and it was almost too hot to hold. I'm going to have to get some rails and heat shields put on ASAP. Thirdly, the front site that came with it does not adjust in increments. On a milspec sight, there is a pin that allows you to adjust the elevation in "clicks". X number of clicks = Y inches at Z meters. The Ruger's is just a straight screw, so there was a lot of guesswork to figure out how much to turn it to get the desired result. Other than that, shot like a dream. The Burris Fast Fire 3 site was a bit of a pain to zero, but she works like a charm now.

Then there is the M-1. Semi-auto, .308, smooth as silk with an ever so satisfying "PING" to let you know you just sent 8 rounds down range. What more can I say about it?
