Things I liked:Very nice BBs, solid, feed well. And, they won't be around in my yard or in the woods forever. Things I would have changed:Not much.. clearer marking of the bottle showing they're bio BBs, maybe a feed spout on the bottle instead of just a cap - minor stuff.
Things I liked:Beautifully made.
Action very much like a 1911 firearm.
Authentic blowback, lock-open slide.
Wonderfully easy to load with BBs (use a bottle with a nozzle on it and just pour them in).
Great for practice and fun. Things I would have changed:Accuracy drops with quick fire - it seems to have issues with sustained shooting with less than a few seconds between shots. (This doesn't sound like much of a problem, but this thing just begs you to keep pulling the trigger!)
The manual isn't much. What others should know:My first gas gun, which I'm running on propane. It took me a little experimenting to get the fill right; I'm not sure that was completely my problem (could be) or if it took a while for the magazines to be purged / settle in.
I add gas each time I fill a magazine (about 16 shots).
Things I liked:Works very well with my new WE Full Metal 1911 MEU Desert Gas Pistol.
I'm getting a lot of shooting from my first 1# propane bottle. What others should know:It took me several tries (and a lot of smelling propane) to get the hang of this, but now I hardly ever freeze myself...
