Hello, just found this site and signed up and need some help on choosing a good sling mount for my M&P 15T. Love the rifle! Just got my optics put on today and took to the range. One small issue I'm having is I want to install a sling mount in front of the buffer tube and I've looked online at different sites and read the reviews and most say that they were hard as heck to put on. I'm no gun smith, I'm sure I can go pay someone to put it on, but this is my rifle. Just a single point mount. Any suggestions? Thanks
