It's sad they don't have a few more variations of the PTW. I like the M16, but it's not my favorite gun. However, the M series rifles are so easy to modify and accessorize you can almost make it look like anything you want. There is a 416 kit available for PTWs now as well. Not to mention PTWs can use almost any real steel accessory, optic, or furniture.
But I've used mine in the rain and snow. I guess my advice, is to disconnect your battery immediately if you think water got inside. Use a can of air duster (computer cleaner) to blow out your boards and optics, then let her sit stripped apart in a dry place fir awhile.
I once played in a torrential downpour, and heavy fog all day. I then put it back in my gun case wet. The foam in the case was already moist. It sat there like that for a week. The optic board failed a month or so later. Also don't use heat to dry your gun out. They really are the best, but not invincible. A minor amount of care is required.
ďREALITY IS LIKE A STONE. TO MANY ITíS HARD AND COLD, THEY CANíT HUG IT OR EAT IT, IT ONLY FRUSTERATES THEM AND DOESNíT DO THEM MUCH GOOD. TO OTHERS ITíS STRONG AND DEPENDABLE, YOU CAN BUILD WITH IT, BUILD UPON IT, OR WORK WITH IT, ALSO USE IT TO SMASH PEOPLE IN THE FACE.Ē
