I've been toying a lot with the idea to buy a GBB M4, esp. after handling a WA one.
What keeps me away from them
- high price of magazines - with WA family at least. Perhaps to be solved with eithre PGC, G&P or KA magazines?
- poor cold weather performance, which would be a problem over here. I can use my AEG during winter, but autumn / spring sometimes have varying temperatures along the day
With the G&P GBB, at least I drop one other scare factor - the big initial price point required to have a full metal solid internals working rifle. Right ?
