Anybody Shoot Powerlyte Speedline Barrel??

[Marcus]

Saw an ad for Powerlyte Speedline barrels in a mag. Thought they looked interesting. Checked for any reviews but there were none. Anybody ever try one of these?

I think I saw those in my APG magazine. Dont they look similar to the boomstick design, but a bunch of porting? If it is those things are about $120. But I would like to buy one though.
