Uhhhhh description This is a Geissele Super Duty 16” upper on an Aero M4E1 lower. I put an hrf concepts magwell on there because I thought it looked cool but it actually helps out with swapping mags while shooting. Weaponlights on both the rifle and pistol are Surefire… Eotech setup is heavy… and the pistol grip on the rifle is by driven arms co. Surefire warden for jokes (and because NFA items are illegal in the state where I pay taxes)
