I had a Mossberg MMR tactical, wasn't the best built AR on the market but someone made me an offer on it that I couldn't refuse so I boxed it up and delivered it to him this afternoon. On my way home stopped in the local gun store to see a friend and they happened to have a Sig Sauer m400 enhanced on the shelf. I brought it home for less than I sold that Mossberg for. While I was there I picked up a Magpul ACS stock and a Magpul pistol grip to add to my M&P 15. I'd say I had a pretty good night.
