  • Omega 9K vs Octane 9. For a 9MM SBR/carbine. Which one is the better option?

    Posted by someboringusername25 on August 6, 2022 at 5:26 am

    I’m trying to decide between these two to pair one of them with a CZ Scorpion.

    It looks like Octane is loner and headier but slimmer and quieter.

    Is there something specific I need to consider? It would be my first suppressor. So I don’t really have any practical experience.

    I have close to 40 cans, and the Omega 9k is one of my favorites. It isn’t the quietest or most durable, but for its size and weight, it’s performance is pretty remarkable. And it is plenty durable for a 9mm PCC. I run mine on an MP5k clone, and I love it.

    Wolfman is great, but it is much bigger and bulkier.

    The jury is still out on my YHM Nitro N2O. I still don’t have the host I got that for. Dakota Tactical should be building it soon though. I’m not sure if I’ll switch this over to the mp5k and put the omega 9k on the Dakota or not. Time will tell. I’ll probably play with a few things and see what I like best.

    I own both the octane 9 and the Omega 9k. In my opinion, for running on a 9mm pcc, the Omega 9k, but it’s not my first choice. My first choice is a Rugged Obsidian 45. Here me out here…..

    The Octane has major back pressure, so much so I get gas and soot on my face from a MP5. On a blowback like a scorpion, the Backpressure is going to be hard on the gun, more recoil, wear and tear, more gas coming back towards your face.
    The Omega 9k no issues with gas, but it’s not hardly as quiet as the octane.
    The Obsidian 45 in short configuration is very similar in size, weight, and sound to the Omega 9k, in full length it’s slightly longer than the Octane but sounds better and no backpressure issues. This is my experience and my recommendation.

    Have both, 10/10 I’d get two omega 9k’s looking back

    The size and weight on the Omega 9k is unbeatable in my opinion. Rather bombproof build as well

    Omega 9k. I have it as a designated can on my scorpion sbr, can’t beat it. Size/weight is perfect and does an awesome job. My scorpion is one of the earlier ones that only has the 18×1 threading or whatever it is. so I went with direct thread. Haven’t had any issues.

    For a carbine? I’d go with the omega 9k.

    I have the Octane 9, it seems cheep as fuck to me when in hand. I would definitely pay the little bit more for the Omega if I had to do it again. Especially if it’s going to be for a PCC. The octane is a budget pistol can the Omega is a PCC can.
