Update on the Chinese Ebay cylinder: So the other night I repeatedly shot this thing over and over in
between rounds of PvZ Garden Warfare - and suddenly it started to lose
power. Eventually it stopped firing and the darts would barely leave the
barrels.
So I took it apart and noticed that the foam gasket was ripped off the compression tube;
If you do buy one of these, be sure to sand down those edges prior to
installation. I’ve shot this thing repeatedly with the sanded edges and
this seems to completely eliminate the problem.
Note that this cylinder was the first of four 7 shot cylinders I have purchased. Here's an overview of all four cylinders.
