I have a Smith & Wesson M&P 15 optic ready carbine (not the "Sport" model), this one has the dust cover, forward assist, and a chrome lined bore, with a 1:9 twist. It is chambered in 5.56 NATO and comes with 1 PMag and a hard case. It has had exactly 10 rounds fired through it, I put an optic on it, and sighted it in, cleaned it, and then put it in the safe. I would like to get $1000.00 for it. If you have any questions please PM me Thanks for your interest.
