Well, my rifle came back today! It came w/ a letter that it had been "updated to current specs" but that's about all it said. I cleaned it before it was shipped it but it was dirty when it got back. They must have shot it several times.
I noticed that the hammer spring was blue. I don't think it was blue when it left but I don't really know. The extractor appears to have a different bend than when it went away.
With more than a little trepidation, I loaded 10 CCI Mini Mags in a new clip, stepped out onto the front porch, and loaded the magazine. Pointing downrange is always a good idea when you let the bolt go forward (if you have M16 experience) and I let it go. It chambered smoothly and appeared to close fully!
Taking my best unsupported standing position, I unloaded the magazine in a timely manner at the stop sign 204 yards away. (Of course, I've never hit the stop sign in 11 years that I've been here but it is a target. Maybe I ought to try it w/ something besides handguns and iron sighted .22s)
Anyhow, it went through the 10 rounds as fast I could pull the trigger. No malfunctions of any kind and the bolt locked back when it was done. The rifle never fired any more than 7 or 8 in a row before and that was a one time deal-sometimes it was one in a row.
Now that I have about 50 rounds total through the rifle, I can start to add them up like the big boys. It was hard to get it "broken in" 1 or 2 at a time.
With the talk about federal law and not marking boxes w/ the contents on the outside, I thought I'd include the end of the box that came from S&W for your perusal.
