Don't hold back, spend the money to get NVG's. Yes, it is expensive but you will enjoy the night experience more. What's $3000-$4000 after all you have spent so far (and yet to spend) to enjoy airsoft.
You won't regret it. I suggest you get:
- PVS-14 Gen3 monocule
- Helmet mounting kit
- Ops-Core Helmet
Good luck, you know you want it.
