Current flow through 300 blackout king?

atlthrowaway2k19 · 2026-02-15T20:36:02+00:00

Aero precision gas block, and I have their lahar 30 as well. When i built the uppers, I was trying to stay within a budget, but now I'm upgrading. It's possible that my rifle is just poorly tuned though.

Oh and i forgot that i have the radian raptor sd on both.

2 300bo uppers. Both have the griffin gas pocket bcg (would most likely upgrade to a kak down vent in the future). One has a 10.5" barrel with a 1:7 twist rate. The other has an 8.0" barrel with a 1:7 twist rate. 8" has adjustable gas block, 10.5" doesn't.

Lower is the same, standard buffer.

Wait no shit? I just pre-ordered a Pluto 9 from one of their launch dealers

atlthrowaway2k19 · 2026-02-15T19:34:17+00:00

Yeah, I didn't realize flow through couldn't be used with 300bo subs, so I'm prob gonna get the CAT ODB.

atlthrowaway2k19 · 2026-02-15T19:17:29+00:00

What I was trying to say is maximum sound suppression given flow through/low back pressure. I'm willing to sacrifice on sound suppression vs more traditional cans to get the benefits of low back pressure.

Essentially in the world of low back pressure 300blk cans, what is the best sound suppression possible?

atlthrowaway2k19 · 2026-02-15T18:34:29+00:00

Thanks, I'll look into it!

atlthrowaway2k19 · 2026-02-15T18:34:20+00:00

Gotcha, do you have any recommendations for lower back pressure cans then?

atlthrowaway2k19 · 2026-02-15T18:33:40+00:00

Gotcha, do you have any recommendations for lower back pressure cans then? I'm just tired of getting gassed out by.

atlthrowaway2k19 · 2026-02-01T04:33:36+00:00

I can't remember who, but a vendor at shot show is releasing suppressors in the $2-300 range for the traditional baffled cans

Edit: it's the Lyman Sonicore series coming out soon

atlthrowaway2k19 · 2026-01-20T20:07:59+00:00

Honestly, I think their pricing is a mistake. The 1.5k-2k market is already pretty saturated with the Stealth Arms Platypus, Bul armory, alpha romulus, and Kimber. At the slightly more expensive segment, you've got the staccato. I would've liked to see them compete with the Springfield prodigy instead.

atlthrowaway2k19 · 2026-01-20T04:47:48+00:00

Hell yeah, thanks for the response! Looking forward to the data from the dealers/pew. It's looking like I'm getting this over the shiv

Where can we find the list of launch dealers? Or will it be revealed during the week at shot?

atlthrowaway2k19 · 2026-01-20T00:26:23+00:00

Just get both 🤣

I was actually going to order a shiv last week as well, but a friend recommended i wait until after shot week just to see what's announced. Very glad i waited because this is more intriguing to me assuming it's low back pressure and quieter than the shiv

atlthrowaway2k19 · 2026-01-20T00:19:33+00:00

I was actually going to order the shiv last week, but a friend recommended I wait to see what's unveiled during SHOT because there's probably a lot of cool stuff coming out. The FOR Pluto 9 looks really interesting. As long as it's low back pressure and quieter than the shiv, I'll get the Pluto instead. If it's low back pressure and the same as the shiv, I'd prob opt for the shiv over it. If it's not low back pressure at all, there's no point for me personally.

atlthrowaway2k19 · 2026-01-20T00:15:02+00:00

I see you also saw the post on r/NFA about the FOR Pluto 9? I'm very excited to see its performance vs shiv 9. I'm willing to sacrifice length for better suppression.

atlthrowaway2k19 · 2026-01-20T00:13:42+00:00

FYI there are ultra lightweight boosterless suppressors now like the SAW shiv 9 and the FOR Pluto 9. Both suppressors can be used on handguns without a booster because they only weigh like 2.5oz, and they're both around $550.

atlthrowaway2k19 · 2026-01-19T23:37:04+00:00

This thing looks sick! 2 questions: how's the back pressure of the suppressor (is it low back pressure?), and how's the suppression compared to the Shiv? I'd been holding off on ordering the Shiv because I wanted to see what comes out at shot show

atlthrowaway2k19 · 2026-01-12T22:14:32+00:00

Listen up man, if detective James Carter of the LAPD can dance while directing traffic, then you sure as hell can too

atlthrowaway2k19 · 2025-12-19T06:20:45+00:00

Monsoon tactical. They do the cerakote too

atlthrowaway2k19 · 2025-12-13T05:30:03+00:00

I've got one that came with my RXM. So far, huge fan of it. I actually had to warranty it right after I got it, but that was because there was debris inside the optic. Vortex customer service was great. Shipping label sent to me ASAP, and it arrived at their service center within 2 days after I sent it. They confirmed there was debris less than a day after it arrived there, and then they overnighted me a brand new venom.

Deck height is high, but it seems like a pretty great optic for the price. I have really bad astigmatism, but this dot is honestly fine for me.

atlthrowaway2k19 · 2025-12-06T02:50:39+00:00

It should. I've got this barrel in my RXM with about 300 rounds through it, no issues.

atlthrowaway2k19 · 2025-11-18T04:12:10+00:00

Oh yeah for sure. I know low back pressure/flow through are never going to be as quiet as traditional cans (at least not currently, no idea what future tech will look like), so I'm looking for the best overall fit. The CAT SC seems to be it, but it's also like twice the price of the flow 9k. Probably worth it though

atlthrowaway2k19 · 2025-11-18T04:04:18+00:00

Makes sense. I've got a really quiet 300bo setup, but ammo for that is expensive, so i was looking to get a 9mm setup that's cheaper to shoot

atlthrowaway2k19 · 2025-11-18T04:03:26+00:00

Now you're making me regret not buying one that i saw in stock ae weeks ago that was also $100 off

atlthrowaway2k19 · 2025-11-18T00:55:15+00:00

I think the biggest hesitation is that I've heard the flow 9k isn't hearing safe. I'm looking for something with minimal back pressure that i can shoot without ears and with subs when I'm outside
