See, to me that reads like "all the annoyances of an AEG with one extra novelty that can go wrong."
The beauty of the GBBRs is that they're mechanically simple with only a small handful of moving parts (essentially they're exactly like GBB pistols, with the slide being replaced by a bolt carrier and the recoil spring being moved to the rear of the system).
In my toolbox I carry a spare complete bolt assembly and a spare trigger set; short of the gun breaking in two, those two parts (along with a few basic tools) will cover any failure I'm likely to encounter: either something with the bolt group fails, the trigger group, or one of the mags (in which case I'm down one mag and I move on).
Now how many people using AEGs have to bring a spare, some people bring two... and sometimes they end up with no working gun halfway through the day anyway.
