This would be my choice. I don't have an Octane, but I am almost positive this rail is large enough to have the suppressor underneath.

Seekins MCSR is another option.

Just keep in mind with any keymod rail that there is limited clearance between the can and ID or the rail, so vertical foregrips may need to be mounted further back. |

There's a thread about Octane 45 HD - Rail choice ... and since the 9 and 45 are the same diameter, it's probably applicable to your needs.

I'm not a fan of keymod, so I think I'm going with the Seekins SAR over my Octane 45 HD. (Even after our CS conversation, Engineer).

If anyone has one of these suppressors can you suggest a nice free float rail....I have a 5'' barrel and wanted to get a 7" rail. If you have pics those are always welcome thanks Knights URX4/Octane 9HD on a dedicated 9mm SBR

Damn there are so many options to build one of these damn things its crazy. So now I am thinking about a 10'' hand guard versus a 7'' anyway the barrel is going to have a 3 lug mount so my question is.....will it be a pain in the butt to put the suppressor on a longer guard if it is not threaded? (kind of a new guy question)

Anyone know what keymod rail would allow the octane inside but still be able to attach a keymod verticle grip to? Any that give enough clearance?

Here is mine with a Quentin Defense slickside upper and 9" handguard. Suppressor is an SWR Trident9. This is the perfect handguard for me on this gun.

Thats a .125 difference, or 1/8 inch. BUT thats diameter. Lets think about radius to find the real distance between suppressor and rail. Radius of rail = .75" or 3/4 inch Radius of suppressor = .6875" or 11/16. 3/4 - 11/16 = 1/16 1/16" Of coarse we can find it by simply dividing the diameter difference by 2.. That rail is going to get hot quick and you are not going to be able to attach anything to it. Better get some welding gloves. They will probably bang against each other too if they are both perfectly machined, and certainly touching if anything is off at all. |

I wouldnt want a metal handguard over a suppressor without a heat shield built in, and those are going to get heavy and probably have fit issues. |

You're using a barrel that's .75" shorter but a can thats 1" longer. |

I meant to ask you, how do you like the Samson Evo rails? Solid even though it uses a stock barrel nut?

after a month of waiting my stamp was finally approved. I have been thinking of going with the seekins bar in 10''. Before I pull the trigger any other suggestions on something similar but maybe lighter?
