Spyder pilot acs '05: 14" tru flight barrel

Did it's job on the marker it came with.
On the marker it came with it did it's job. When used on a spyder tl-x when the pmi was lost it was able to be shot out of the marker about 10 feet. It did stop the paintball but if more than one would have been shot then it was no longer in place. Should have some o-rings on it maybe that would help.
A plug or sleeve really don't matter as long as you use something that works on your marker. I know it is a pain in the butt but you should test it just to make sure.
Did work on marker it came with. Didn't work on others.
I think should fit all. SAFETY is supposed to be number one.
