Airsoft Mike got a Nuprol Case for this KRISS Vector, and a pretty large one at that for this KRISS Vector AEG... "A new case I picked up for my Krytac Kriss Vector! I also preview the optics I intend to use! NOTE: Pelican cases are superior, but cost a lot more! The Nuprol Hard Case is widely available in the UK via most UK airsoft retailers or from Amazon UK or Ebay!

Prices from £60.

External Size: 109×39×15cm(42.92*15.35*5.91 inch)
Internal Size: 101×32×12.5cm(39.76*12.59*4.92 inch)

Currently there are no distributors in the USA for this, but I will keep you updated when it is more widely available.

This case from Nuprol includes an Air Valve.

The valve is basically a pressure relief system for cases that are air tight. It's there to allow the user to relieve pressure slowly so the inside equalizes with outside air pressure. Opening an airtight case under pressure, can damage the lens in optical devices such as cameras, scopes and other equipment."
