I haven't personally fielded this, but I bought it as a project and decided to go in another direction.
Upgrades include:
* Brand new LPVO - Crosshairs with illuminated red dot (just put in a brand new CR2032 battery)
* Collapsing bipod (never used)
* New A2 birdcage (pictured with orange painter's tape)
* Vertical foregrip
* Metal flip-up iron sights
* Two extra magazines (three total)
* Brand new soft case with backstraps
It also has battery, Charger and I'll throw in a box of BBs
