Hope this is a good forum to post this problem in. My buddy I took shooting his first time a few years ago picked up the S&W MP15-22 about a month ago. It lasted less than a hundred rounds and was on its way back to S&W broken. Just got it back, and another hundred rounds, and its broken again. He says the extracting pin and spring are toast and that's what happened last time. Here's a pic of what just happened.





Ouch. He was shooting Winchester hollow points.

He's taking it back to the gun shop tomorrow and replacing it. Should he try another one, thinking this one is purely a lemon, or spend some more $$ and get the Colt Umarex M4 in 22.
