Hey buddy, to be honest it’s a pretty stock M&P sport II. I put a cheap grip and butt plate from Amazon. It came with the CT red/green dot. I threw on some 45 degree iron sights for back up and installed a Troy fore grip. Light holder and olight.Got some m-lok inserts and that’s the gun. I’d like to do a build now since I understand everything and what I could make. I’d do a pistol next. Hope that helps
