A sling is imperative if you're running any other weapon system (or need to do anything other than hold a carbine).
A weaponlight is something I consider to be non-optional on serious use guns... even during the day. They don't have to be huge, but it does have to be enough to illuminate stuff indoors or at night.
Iron Sights - same idea, things break, optics fog; for the cost and weight it's silly not to run some.
An optic isn't required, but a solid red dot (Aimpoint PRO, H1, T1; EOTech EXPS) or low powered variable (Vortex/Trijicon/Nightforce 1-4x; Leupold/TrijiconVCOG/Swaro 1-6x) is a big force multiplying addition since they're easier to shoot especially at night or in awkward positions.
Anything else on a weapon I have to justify to myself as being worth the weight penalty it comes with. Suppressor on my short barreled rifle - yes, but I no longer want to put a heavy optic on it. IR Laser/Illuminator - if I have NODs with me sure, the rest of the time that lives off the rifle. Control accessories - if I shoot quicker with specific stuff it stays. It even applies to barrel mass - if I don't need precision, then I don't want extra barrel mass hanging off the front end of the rifle.
