I have "two" S&W model 15-6's that are pre owned LE Trade ins to sell. Blue is about 85-90%, mechanically tight and in time, sights are good and not beat up. Forged steel triggers & hammers. $425 plus shipping to your FFL.
If interested and you want pics let me know.
Had 6, have two left. Typical LE gun, carried and not shot much.
