    That's nice to know. I had no idea. But I like the red, go for that. Some shade of blue or teal might look neat with a silver or grey outer tube.

    We're gonna try something new here soon. I found a great price on 422 stainless bar, which is not as corrosion resistant as 17-4, but performs much better at high temperatures (600° F-1,200° F). It's a more complicated heat treat, and machinability is lower, but should be more resistant to flame erosion and deformation at very high temperature. It's often used for turbine blades. The alloy is actually really similar to Inconel 718 in many respects, but less expensive.

    It probably won't supplant 17-4 for me, but I think it'll be interesting to see how baffles, especially blast baffles, hold up between the two alloys when subjected to full auto fire.

    That seems like a good lineup!

    I'm sure you're going to offer THR members a discount of sorts? Haha.

    A touch over wholesale, so $580 on the Phoenix and $880 on the rifle cans with brakes.

    At some point here we'll get some video. Plan was to do that weekend before last, but a bunch of other goobers showed up at the private range, making it just about impossible. I did have a chance to run the Phoenix XLV and Phoenix IX against a Rugged Obsidian, and a dozen pairs of ears confirmed that they're noticeably quieter. And that was the 1.25" diameter x 8.0" long IX prototype, weighing just 9.5 ounces with piston. So shorter, slimmer, lighter and quieter.

    Phoenix IX on the Beretta, with the prototype 1.375" x 7.0" IX below it and SiCo Osprey above.

    I did decide to just do black anodizing on the baffles for now. It's the easiest to get consistent coloration with from batch to batch until my new shop is up and I have room for more dedicated set ups.

    I also did away with numbering of the baffles with progressively thinner cones. It complicated production immensely and only saved about 0.3 ounces. They're all just .050" now.

    Maybe by the time you get production up and running I'll have the cash to pick one up. I love the idea of the slim long can...

    To follow up, did you notice a significant difference in terms of noise between the 8" and 7" Phoenixes?

    Well, the 8" IX is 9mm, while the 7" XLV is .45. They have similar internal volume, but the IX is smaller diameter and a different baffle system. The IX seems a little quieter with 9mm subs than the XLV, but that's probably attributable more to the appropriate aperture size.

    On baffle color; a color might be handy for marketing purposes.

    Another consideration might be for production purposes. You could turn out a batch of .30 cal bore baffles and have them one color; then have a stack of 6.5mm a differnt color; and .22, etc. That way you could stockpile them in bins, waiting on when a specific caliber is ordered. This would be more for making your machining time more practical.

    Or not; just a thought, and only 2¢ worth at that.
