There is a small indent, about the size of a pinhead and not deep enough for me to stick one in, at the front end of the receiver on my scout squad. It's not causing any real trouble but it's got my worried that my receiver may have bubbles or other deformities in it. The gun is fairly new (Only around 350 rounds through it as of now), and I'm concerned about it's structural integrity. Is it nothing or is it something I should get looked into? This is the only such indent on the entire receiver (I combed over the whole thing looking for more after noticing this one) but I am looking for others' input
