I definitely did not come by here before I bought my WE 416. Learned a lot from buying this. All the maintenance required, but in the end I love the feeling of every shot fired through this thing. Also learned that not every gun works out of the box. My buddy picked up a new 416 about a month ago and problems are adding up with his. I bought mine used, closed-bolt and it was still stock, nothing wrong with it.
Eventually I think getting one of each (GBB & AEG) would be a good idea. And yes, pistols need to be GBB!
