The price is going to depend on many things and can be as low or high as you want to make it, basicly a housing is going to set you back about 1000$, you can probably find some for less and you can probably find some for more. and then the tube, you can get a GSCI gen 2 tube for like 1500$, not sure on the exact price for that (new). or you can get a photonis XR5 from Europe for 8000$ roughly, or any myrad of gen 2 tubes available from any number of manufactures. So your cost is roughly 2500-9000$.

You could probably do it for less and you can deffinantly make it cost more.

My advice is, unless you have a serious hard on for the pvs-14 housing, which is kinda shit compared to some of the new housings (although its still a great housing, and i do personally love it), just get a generic gen 2 tube like a night optics D300 SHP, or any other gen 2 tube thats available, the GSCI gs-14 etc. and of course, you could just drop the ~3500$ on a used gen 3 pvs-14. Gen 2 will be fine for airsoft, gen 3 and like the super high end gen 2 like the XR5s are obviously better but really any decent gen 2 or better is going to give you a pretty fun night game.
