CYMA MP5SD.

Monstrom 3x prism optic on it. I replaced a venturable TRS-25. The Monstrum has a crisp and thick reticle which I find makes it perfectly usable for CQB, while the magnification makes it more useful in the woods.

A faux laser box (real lasers in airsoft is a huge pet peeve of mine) to hold batteries for easier access. A Surefire M952V light with a simple on/off function, which is great because strobes are pretty dumb. Amazon cheapo 1-point sling works decent enough, a 2-point adjustable feels a bit too cumbersome on such a relatively short gun.
