Has anyone tried the Keymo adapter for the optimus? I think i would prefer this configuration to the mid-length configuration on something like a 300 blackout only since it probably wont be able to do 556 withought the blast baffle. I've had the optimus come loose on me a couple times already and im not too confident in griffins taper mount system. and yes, I strap wrenched it on. Still comes loose. View Quote The taper per mount is very snug. Almost too snug, if you over tighten it, it can be hard to get off. |

I am reading the card that came with my Optimus. Some WTF questions come to mind:
1) It says the 22 end cap is only compatible in short config. Does that mean I can't use it in full size config to shoot 5.56? That makes no sense. 2) Can I use a taper mount minimalist brake with it in full size config or does going full size require the 2 port paladin brakes? |

No, you can use any taper mount device in the full-size. Only the minimalist and Palidan 2 port devices work in the mid config View Quote |

Anybody know if I can run this can on a 12.5” 6.5 Grendel barrel in the mid size config?

And I continue to love this thing on every gun I shoot with it.

Is there supposed to be an O-ring between the booster cage andcap on the piston assembly? (or 3-lug assembly)

There is an o-ring on the ID between the piston and piston retainer, there is not one between the retainer and the piston housing.

The Optimus is no longer rated down to 7.5 inches on a 556 correct? Its listed as such on the first page of this thread by GA? View Quote |

Quoted:
Ever an official answer to this? Everything I see currently says the limit is the same, 10.5 inches for 5.56 regardless of whether you use the mid size or full size configuration. So, no benefit to using the longer/heavier full size configuration on a 10.5in 5.56? I realize that the number of baffles is the same either way. View Quote View All Quotes View All Quotes Quoted:

A 7.5" barrel with something like the paladin brake and a slow rate of fire is a whole different ball game than a 7.5" with a FH and doing mag dumps. It's all relative. Q cans have no barrel length restrictions but did you see the pics of their suppressor that some guy did several mag dumps in a row with a 7.5" diablo? |

Quoted: The very first post in this thread when GA announced the Optimus lists 7.5" for 5.56 in the full size configuration, but currently their web pass says 10.5" for both. Maybe things changed since it was released, but I notice that there are different barrel lengths for .308. Since I've already paid for an Optimus, I'm interested it it's limits, not so much other cans that I don't have. View Quote |

Silencer Shop did some independent testing of the Optimus in the full size configuration.
Failed To Load Title Their testing was pretty consistent with ours. I believe we got 118 DB with the rimfire cap in the rimfire config. Nice performance across calibers in general. Concerning the specific back pressure question I'm not sure which config would have less. |

Do you need the fixed barrel adapter to use the Optimus on a Beretta M9A3?

Thinking about doing a 9x39 build. I understand that the 9x39 is slightly larger cal .362 vs .355 for 9mm. Can I use my Optimus on this round or is there too much danger of a baffle strike?

So planning to use my Optimus on a Scorpion. So looking at options.
Thinking fixed barrel spacer and direct thread, or, Taper mount with a minimalist device, or Or three lug. Most expensive and also out of stock right now. Anyone have advice? |

Quoted: Taper mount minimalist device is going to be heavy since you need to either use the full taper mount extension, or pay extra for the minimalist blast shield. Also, I think the only taper mount 9mm device they make with 1/2x28 threading is the hammer comp. Make sure you don’t use the rifle blast baffle since it has a .30 cal hole, not 9mm. I’d go direct over thread over piston + fixed barrel spacer just for weight. In fact, DT is going to be the lightest option. 3 lug is probably the best for PCCs, but it weighs more than DT. View Quote Dunno why they made the blast baffle .30. Wonder how many people have shot 9mm with it in. |

Quoted: I don’t think they offered a taper mount muzzle device with a 9mm opening until recently with their 9mm hammer comp, so I don’t think there was anything compatible. I don’t think the hole in blast baffle will even allow 9mm to pass through, so if anyone did, it would have been just once. View Quote |

Quoted: No but can be used with extra baffle. Also the minimalist stealth FH is available in 9mm View Quote |

Sorry I'm so late to the game on this one but you can use a Plan A adapter and mount the short config optimus onto a 9mm taper mount muzzle device (i.e. hammer comp). I've been using the Plan A on my 300BLK pistol with good results.
The Plan A actually threads into the mount housing (where you would install the pistol booster or the tri-lug adapter) and not directly into the rear of the suppressor. Depending on how dirty the ammo is you'll likely need a strap wrench to get it back apart after heavy use. https://www.griffinarmament.com/plan-a-taper-mount-adapter-1-125x28-for-griffin-pistol-silencers-and-others/ |
