WTS: Laserlyte Smith & Wesson Rear Sight Laser, fits all M&Ps, purchased new, installed on a new S&W M&P that sat in a safe, decided to sell pistol so the sight was removed and is now for sale. Includes sight, all factory paperwork, an extra battery and all wrenches. Allen bolt in top of sight is a little tough to remove, probably just needs a better wrench. $108 shipped, PP (+ fees) or MOs gladly accepted, please contact me with questions via e-mail at jbsf3jbsf3 at gmail . com with any questions, thanks.
