PTW's have their place with rich albertan airsofters, but for $2000 you can have a fully upgraded G&P M4 AEG, with a mosfet, that's reliable in the rain, fully upgraded with prometheus parts internally, over a dozen mags, and various external accessories.
My Magpul M4 is fully balls out loaded externally and internally, with mags, batteries and triggermaster it's still under $2600
And it doesn't short out in the rain
But PTW's REALLY don't like to get wet, as Jonas would tell you lol
But every other day of the week they work great
