LNIB Smith and Wesson M&P 15-22 Slide fire kit (installed) 3-25 round factory mags Slidefire kit came with upgraded CMC 3.5 lb trigger and a recoil enhancer muzzle break. Factory parts will be included I only say LNIB cause I got this in a trade. The original owner never fired it and either have I. After breaking it down it shows no sign of being shot. Asking $600 firm for the complete package and will even throw in a zip lock bag with 200 rounds to get you started. Will not separate the package. As in trades I'm into 9mm pistols. Same value but I can add a little cash depending on trade.
