Rumor is somebody on here got two of those recently, or at least something very similar...and very pleased how it performed.
I bought one and it is impressive. The tolerances are tight, construction looks good. Mine is a paperweight but, I'm considering my options. There's a black one on ebay in aluminum with stainless steel components for $15 from China. Spending $200 for a tax stamp alone makes me want to go ahead and buy a pre made high quality suppressor. Thanks to Big Waylon for pointing me in the right direction to buy a good one. I've played with this "fuel filter" quite a bit and for the price, it's not a bad idea to buy a couple.
