These are my short list choices for a flow type can, with "best" defined as these attributes:
Requirements: 7.62 and (Hard Use / Inconel / 17-4 Steel / Haynes 282) and (Flow / Low Back Pressure) and Hub Compatible.
No Ti cans, even if they market as hard use / FA. Must have LPB, or be considered a Flow type. Must be HUB compatible. Flash and Recoil suppression are bonus attributes.
I looked at these choices:
- Radical Defense CS-3 7.62
- Rex Silentium ULBP 762
- CAT ODB 718
- SilencerCo Velos LBP 7.62
- OCL Polo 30 (Not Really Flow Tech, but good value for Hard Use)
- Replicator Ventus 30
- LMT Ion30
I could also choose to wait for (or just get it when available):
I use a Rearden Atlas mounting ecosystem (Bravo 1.375x24, and Charlie 1.375x32), and Liberty Bell Precision, Ecco Machine, and Rearden muzzle devices. I like LPM muzzle devices for their ability to diffuse a blast from their Flash Hider model line without needing timing to the barrel.
I am still inclined to not select Ti cans for high power factor use yet, with my cutoff at about anything above 300 AAC BO. Sparking is still a concern for me, and I remain unconvinced that it ever goes away completely. I do believe the Ti particles that remain post-manufacture can be flushed out and blown out by use. But I have seen enough cans still sparking even after break-in and flushing, that I'm not yet ready to jump for the high power factor use case. Not Yet. If you really want to know if it has stopped sparking, you have to watch them in a darkened area, or at night. My .02 is, Ti cans continue to wear out over their lifespan, and that is what you see when you look for it. The type of muzzle device makes a big difference about how long that will be with Ti. MDs that focus the blast forward are harder on Ti cans, and shows more sparking. I have adopted the idea that cans are wear items, and I will replace them as they wear out. (I want to try too!). For now, I'm exploring flow models, but not flow and Ti.
For the CAT Ti models, a couple of other makers have bought them and took a saw to them, to open them for study. No pictures were published out of respect for design copyright, but an "opinion" was published stating that the internals were "thin" and were, in their opinion, not fit for hard use. I'm offering this view as an overall guidance, which is to pay attention to the comparative weight of the Ti cans you are considering. Lighter is better sure, up to a point. The CAT ODB Ti was removed from my flow short list. They do make an Inconel model.
The LMT models have a rep for being loud. The Ion dropped off my list. This is Not Lewis Machine and Tool, they are someone else.
I could not learn much of anything about Replicator or Ventus 30. That was a dry well.
The Polo 30 is on the list as a "Kentucky Windage" (see what I did there?) for value. Not really a flow type can.
The list is shorter, but there is another couple background factors: Whats available, what will I have to wait for on backorder (almost everything these days), and what is the outlet that can I obtain it through? That last idea can add another $100 to $200 onto the overall price, and it does drive my selections when a transfer fee is charged that I can not avoid. It becomes a matter of "best among the best" type of decision.
I bought a Velos LBP. It meets all my requirements, and my use case. It's a Charlie thread interface, and I got a Rearden Atlas in Charlie, no "Charlie to Bravo" adapter needed. It was available to buy without waiting, and without a pile-on of transfer fees. It had some testing information available, and though the test results indicated it was not the top at sound suppression, it was a front runner in it's peer group. That it was not "back of the pack" was good enough test results for me, looking for an overall balance of flash and noise suppression.
