I own a Dead Air Mask. I’ve also played around with a bunch of different rimfire silencers, so here are my comparisons of the Mask versus the other cans mentioned in this thread:
-It’s quieter and has less first-round-pop than a Sparrow. (The Mask has almost no discernible FRP. Some people don’t seem to care about FRP, some do. I definitely do.) The Sparrow is a little easier to clean though, thanks to its monocore design. The Sparrow also doesn’t need a tool to take it apart.
-The Mask is shorter and lighter than the Spectre II, it’s just as quiet (if not quieter), and it’s rated for the same calibers. The only advantage of the Spectre is that you don’t need a special tool to take it apart (you can use anything narrow and straight like the back of a knife), but the Mask requires a proprietary tool for disassembly.
-The Warlock II is the exact same design as the Spectre II except it’s made of aluminum, so it’s lighter than the Mask. But the Mask is a lot stronger and can shoot up to 5.7mm, whereas the Warlock isn’t rated for magnum .22 calibers. The Warlock is also harder to clean thanks to the aluminum baffles.
-The Mask is just as quiet as the Element 2 and it’s a lot easier to take out the baffles when it’s dirty (the Element actually comes with a special screw tool to push out the dirty baffles because of this). It’s also rated for 5.7mm, whereas the Element 2 isn’t.
The other three mentioned (Oculus, Switchback, and Bitty) I have no personal experience with, but here are some observations:
The Bitty might be small, but its going to be loud because of that. Also, the baffle design looks like the old pre-SilencerCo SWR Spectre I’s baffles. There’s a reason why they upgraded to the Spectre II...
The Oculus and Swichback seem cool, but I currently have no interest in a modular .22 silencer. To me, the point of a modular can is to shorten it for home defense where you want more maneuverability around your house and you don’t care about being super quiet, you just want to avoid blowing your ears out. And then you use the longer configuration for recreational use where you want it to be quieter. My .22 can is solely for recreational use, so I don’t see myself ever using the short configuration. (But hey, maybe I’m wrong and I’d end up loving it. Perhaps I’ll get a modular one if I’m ever in the market for a second .22 silencer.)
And as for the different baffle configurations for the Switchback, that seems cool but I probably wouldn’t switch it around all that much. I’m very cognizant of lead exposure because I have young children, so I only take apart my .22 can under controlled conditions during a cleaning session. If I had a Switchback I probably wouldn’t change it to the rifle baffle setup when moving it to my rifle, so what’s the point?
