I have a S&W M&P15 and I love it. I got it a couple of years ago and haven't had any malfunctions or issues with it. I've got it sighted in for 100 yards since that's as far back as we qualify at work. I have the MOE edition with the Magpul Handguards, Magpul BUS, and it had the Magpul pistol grip, but I put a Hogue grip on it along with the Magpul MS-2 Sling. For the price, you can't beat it.
