I finally got to my secret range today (been super busy lately), and I took the SR1911 and the AR-556. Both ran perfect, with no issues. I put 100 rounds of FMJ through the 1911; it is such a joy to shoot, and it is quickly becoming my favorite handgun. I ran 120 rounds through the AR. A member from Sigtalk (which is another great site, full of quality people) gave me a red dot scope for it, which I hadn't messed with yet. I dialed my iron sights in first, then messed around with the red dot. It is way off- I have no idea how much the previous owner may have adjusted it- so I didn't get much accomplished bringing it in. A friend of mine knows much more about them than I do, so he's going to help me. I ran the AR first, so that it would have time to cool down while I put rounds through the 1911. It was a great morning.
