Review: Liberty Suppressors Chaotic

[strobro32]

What are your specs Strobro?

8.2" Noveske barrel
Extended feed ramps
Pistol length gas system
Full auto carrier
Carbine tube and spring
H2 buffer weight

If you reload, remember that Noveske barrels do not have SAMI spec chambers. Pressures are higher than published bullet and powder mfg. load data. Start low and work up loads on high velocity and work down on subsonic loads.

Much appreciated!

Did you meter the Mystic with 300 blackout? I would be curious to see how the Mystic compared.

I don't remember if we did or not. We had limited time that day. I'm headed out the door and don't have time to skim through my review.

You've got an extremely fast moving cone of expanding gas, and the baffles need to 'intercept' this gas. just having more of them over the same distance won't put them in position to grab and redirect any more gas. Having a handful more baffles for a given design can make it a little quieter (m4-2000 mod8 versus mod6), but those baffles also do take up volume, and keep adding them and eventually, you'll start really hurting performance (and weight).

there's also a simpler aspect of why the can's length improves performance- and that's that the gas is fast, but slows down/loses energy pretty quickly, so the further it gets from the muzzle, the slower, cooler, and "quieter" it is. Cover up as much of this process with a can as possible, and what makes it out the end of the can will be less noise.

so an efficient design would be a 1" diameter 12" long?

More efficient than 1" long and 12" dia, yes.

you balance it, but you get diminishing returns real fast on diameter. You also get diminishing returns on suppression from length, but not as fast as with performance from diameter.
