I have a like new Sig M17 that I never shoot. It has a Burris Fast Fire 3 that is brand new that comes with the box and stuff. The optic plate is a Springer precision plate made specifically for the Burris Fast fire 3. Comes with the factory case and 4 mags. All that in a retail perspective is almost $1000 if new. $700 takes this one home. 4o5-568-5o8o
