Low profile, in line with the bore (helps some with working corners), ambidextrous, takes up minimal space for an ambi setup (compared to an M300 with an SR-07, for example), but the biggest thing for me, is you get twice the output and much better throw from an X300U-B vs. the M300.
Light setup is mostly preference, though, so try what you think you'll prefer.
Get an arisaka defense light and keymod mount. They are fantastic. Malkoff TIR heads, SF compatible, made in the US, and reasonably priced.
As others have said, buy more lowers, high quality mags, and ammo.
Also, it doesn't appear your receiver endplate is staked into the castle nut, though I can only see the one potential staking location on the right side. If it's not staked, you should do so.

Ammo, mags etc...ban items basically
You can always buy a flashlight etc
IR laser is something you'd probably already have if you had nods and acquiring those is a mfer.
Get an SR lower for that thing.
Mags & ammo, replacement parts such as rings, firing pins, extractors, various springs, and a light (Surefire is a good choice). Pretty much in that order.
