cousins DTU shot out of battery today then shot off 5 rounds at a time. He called S&W and they told him it was the first problem they had heard of with the 15-22, he directed them to this site and others. The gentlemen then asked for his serial number again and he said oh ok, does yours have the blue springs in it because, THEY ARE WEAKER* Yes, he said the blue springs were the problem springs and we know that isnt the case, and it needs to be updated (***?) The guy just told him they had never heard of problems with it, then when he says something about the forums the guy asks him for the SN again and tells him to send it in. Guy also told him that with this problem it doesnt take too long to fix. why the heck would they tell him that they hadnt heard of any problems and then turn around and say that people with this problem usually get their gun back in so and so time. Sucks for him though, we had been bragging on his rifle. FWIW he was shooting federal bulk and winchester 333. Got an OOB with both. it blew the back end almost completely out of the case of both, (ive seen pictures of what he described on here and so has he) OH well, another one bites the dust and nobody was hurt. they sent him out a box and shipping label.
