Hello all,
I made a introduction thread and posed the question in there but thought it might get more visibility here.
I bought my M&P 15 Sport back last November but wasn't able to get it out to the range until this past Saturday (2-4-2012).
Everything went overall pretty well for it being my first time using a AR-15 but I did have to concerns.
1st concern was how extremely hot the barrel got. It was so hot it was smoking some and untouchable for a good 15 plus minutes after the last round was fired.
The guy I was there with brought his home built AR and within moments after using it he was able to touch the barrel and put it away in his bag without issue.
As this was my first outing with it, I'm not sure if this is expected or if something was off with it.
I put probably 120 or so rounds through it while there.
2nd concern is I feed issues. I had on more than one instance what seemed like it was trying to double feed. A live round was chambered and for some reason it got to a point where it was trying to put a second round in to soon.
I'm inclined to think it was because of the flex of the stock plastic mag and it being the first time being used. I have 3 Magpul mags same as the stock mag and 2 of the 3 had this with the initial few rounds being fed.
I've since taken them apart and cleaned them out really well and made sure they have clean and proper movement. I'm hoping that was a 1st time being used thing and won't show up again.
