Things I liked: Mine kind-of fits into my Well MB05, it holds it in, but if enough force were to hit or bump it, it would pop out. I would recommend super gluing it.
Things I would have changed: Maybe make the piece that goes into the body of the gun slightly longer? Not really anything.
What others should know: Mine had a couple dings on it, where silver was showing, like it had been used before, but i don't really notice it. This is still a pretty good deal for the money however.
Things I liked: A good BB bottle, has a good, tight cap and holds 1000.
Things I would have changed: nothing
What others should know: BBs aren't too great, but that's not why I bought this, I mainly bought this just for the bottle.
