No Tube?

No tube indeed. We have spent a lot of time developing and perfecting the Patent Pending SOS or “Screw on Stack” design. As far as we’re concerned, tubes are for the past.

Only Five baffles?

Yessir! While doing some gas flow simulations, for giggles we said, what if we swap more baffles for more airspace? Frankly we were shocked at the simulation results so we decided to build one and test it. It turns out a solid mix airspace and baffles is great, go figure.

Does it come unthreaded when firing?

No, it does not. All you need to do is hand tighten it snugly (no need to get too tight or strain tightening) when assembling it and you’re ready to rock.

Aluminum baffles? Doesn't aluminum suck?

No it doesn’t. There are different grades of aluminum. We machine a solid round bar of premium grade 7075-T6 to make this suppressor. All aluminums are not created equal and 7075 is king. It’s super light and as strong as steel. The issue with aluminum is the melting point. Over 600 degrees F and it can start to get weird. However you aren’t getting this puppy to 600 without some truly radical shooting. Light bump fire? sure. Belt fed full auto? As my Italian friends would say, fougettaboutit.

How do I clean it?

Here in lies something very special about the SOS-Thumpa design. The key to suppressor cleaning is maintenance. The problem with practically any other suppressor is it’s the devil to take apart, so of course you’ll not want to maintain it regularly (because you aren’t a glutton for punishment). With the SOS-Thumpa you will be able to disassemble the suppressor easily by hand, wipe off the crud, apply a thin coat of fresh lube (frog lube paste works wonders), and reassemble in less than a minute; with your eyes closed.
