Piston housing is stuck after 50 rounds of perfecta. Any advice on how to brake it loose without heat? My strap wrench is slipping and I can only use my hands to grip the tube. The fixed mount came off but it did not come out smoothly. There was a lot of crud on the threads and it felt like it was binding up while I was unscrewing it. I was not able to unscrew it by hand after breaking it loose. Had a weird experience with this perfecta ammo too. I wasnt able to get any hits on a 2'x3' target at 50, 25 or 15 yards coming out of a cz scorpion + optimus. When I took the suppressor off everything was good. Tried some PPU 158 gr w/ optimus and those were on target. Decided that I'm not gonna shoot anymore perfecta out of this can. It's dirty as hell and the bullets are disappearing into thin air seriously though, it's dangerous. Spent the next 40 minutes trying to get my suppressor apart so I can run my ar with the taper mount and had no luck. View Quote The only part I tighten pretty good is the inner end cap since that helps keep carbon from getting in between the baffles and housing. Everything else just snug. I check everything pretty often but haven't had anything come loose I also use copper antiseize in the stick form on all the threads Since I started this method I've been able to get everything apart without tools |

The seafoam worked. I still needed a 3rd hand to break it loose though.
Thanks for this advice though. I was beginning to regret buying this can because it was too difficult to "transform". Hopefully this will make things easier. The more I think about it though, with all the money I've spent on this 1 can, I could've bought a Recce and a Revolution can for not much more. Don't get me wrong though. This is a solid can. |

What would be the best route for mounting the Optimus on my DDI AK47 with 14X1LH?
It being a american made barrel the threads should be concentric. The owner of DDI confirmed this at the youtube shoot late last year. Of course I will check. |

View Quote If you have the A2 mount you'll have even more options They also make an adapter from 14x1 LH to 5/8x24 that gives you a shoulder so you could use muzzle devices that need timed. I'm also looking for a mount right now and I think I've settled on the AK flash comp. I have the A2 mount/blast shield already Even though your barrel is American made I'd still make sure to check alignment. If you don't already have them the drill rods from McMaster Carr are only $6. So far I caught two barrels that would have caused baffle strikes. One was a Ruger and one was a 8” 300 blk |

I have bought a Optimus and now waiting for my stamp. I also waiting for a stamp on a Scorpion and AR 300BLK 8.5". I will most likely also get a .233 10.5" upper down the road. Can I run the short configuration with my .300BLK in Supersonic or only in Sub. If so what connection can I use. When I bought it, I didn't realize that the different connections had different ratings. I am guessing that my Scorpion 9MM has the same ratings as any 9mm Pistol and can use any of the Short connections with that. I am also thinking of running partially under the hand guard so wondering how a connection will work with my .300BLK build.

3-Lug Configuration (with Griffin 17-4 PH 3-lug couplers):
5.56mm limited full auto down to 16" 5.56mm Semi auto 14.5" .300BLK supersonic limited full auto to 9.5" .300BLK subsonic full auto to 8" I was thinking of using the 3 lug, but here is says supersonic is 9.5 and 5.56 is 14.5". Am I not understanding this information right? Also can you direct thread when running supersonic, and understanding it right that you don't want to direct thread 5.56? |

That's right. I thought there was a limit on the barrel length in the short config but didn't go look. View Quote View All Quotes View All Quotes |

Hey guys!!
I would like to pick up a direct thread fitting to run on a m92 7.62x39 sbr (that Morgan cut concentric threads on in 1/2x28, can i run any taper mounts that will fit a 30 cal bullet in 1/2x28) and i want use it on some rimfire things. Which one should i get the taper or fixed adapter? thanks rob |
|
The cheapest option would be to go with the 1/2x28 direct thread taper mount and you would run it on both the AK and the .22lr, or just use the pistol booster to run on the rimfire.
1/2x28 on 7.62x39 seems pretty odd though. I would double check that. |
|
Thanks. Direct thread taper so I can use it in the full-size config? The barrels are skinny on those m92s so 5/8x24 wouldn't work.
|
|
You could use the full length or if you have the minimalist blast shield you could use the midlength configuration as well.

Bought a pelican 1170 for mine. Anyone have a pic of how they set theirs up?
Just curious. I'll post a pic of mine once I have the time to devote to cutting the foam. |

Here's how I did mine. I don't like the way the tool and pusher is at the bottom. If I had to do it over I'd probably put the tool and pusher in the center between the main tube and rifle extension tube. Either way, I'm not changing it as it is waaaay better than humping it around in the cardboard box it came in. http://i.imgur.com/3JNDbtx.jpg On a side note I tried a number of different ways for the image (not just the link) to show up in the post with no luck. Anyone want to PM me on how to fix it so we don't garbage up the thread? View Quote |

I set it up so the heavier parts are towards the hinge side of the case. I'm not sure that it matters but it works just fine.
I got the case off of Amazon for $35 or so. The pluck and pick foam was easy to work with. I made a couple of 'whooops' moves and but I shoved the foam back in and it was good. I guess you could use some adhesive to hold it back in but I didn't need to. |

You can kind of see the size of the cubes, 1cm x 1cm. They were real easy to work with, I don't think you could cut them.
If you look at the top left corner you can see that there is a layer of foam that goes all the way around the case that you can't (shouldn't) cut. Other than that layer you can pluck at will. I put the 22 caliber endcap under the plastic hex tool. In the end, $35 and about 10 minutes of labor is well worth it to protect a $1000+ can. |

View Quote I haven't had much time to play with it but I'm hoping it's possible to turn the rubber wrench and piston housing/booster assembly on end to save a little space too. I'm hoping to make room for another accessory or two. But this is a great example! |

What Griffin needs to do is make a endcap tool so we don't have to use the piston.
Once the piston is used its nasty and you get that crap all over your hands, having a tool that doesn't go insane de the suppressor will go along way to keeping hands clean. |

Here's how I set mine up - really happy the A2 mount and the booster assembly fit vertically with no cutting the lid or bottom foam! Saved a lotta space. Might even have room for a minimalist blast shield in there...

Did mine a few weeks ago as well. Figured the cardboard box would not hold up long and want to add storage for the mid length tube and direct thread adapter. http://i1046.photobucket.com/albums/b468/vmalchesky/C460B231-D21B-4179-96D1-028AB9D7E850_zps4zwm2p5t.jpg View Quote |

It's one they sell at the container store and online. The actual foam sextion that comes in the box would drop in to this case.

Have a question.
I have a 10.5" 5.56 with minimalist brake. When in the short Taper mount config (short expansion Chamber), is it safe to use the 22 cal endcap? Shot it this morning and it tamed the noise considerably but wanted to see if the 22 end cap would quiet it down more. Seam like I read somewhere that the 22 endcap was for the shortest config possible. |
|
If I recall the 22 end cap for 5.56 is only to be used in direct thread and 3 lug configurations.
Their CS is pretty awesome though. Just shoot them an email / call. |
|
They later came back and said the .22 endcap is usable in the mid and long config
|
|
Hopefully they chime in on this as I use taper mount in mid and would like to try it.
|
|
It's safe to do. That's how I run mine all the time.
In fact, I've never had mine in the full length. I run the mid on my 556 rifles and on my 6.5cm rifles If all I'm shooting that say is 556. I change the end cap to the .22, if I'm mixing it I use the 30cal/9mm |

Thanks guys for the feed back, I will have to test it out when I get home.
On another note. Is anyone else having a hard time locating a minimalist taper mount stealth flash hider in 14X1LH? |

Look forward to hearing the results. This is good news because I see me using it in 22lr and 556 the most. Being able to keep change one less thing to swap back and forth is good news. I am using direct thread in short configuration for 22lr than mid for 556.

Just want to add, I was in a video hangout with Griffin today and I asked about the 22 endcap for my alpha and if it was worth it to get the 22 endcap.
Their view was that, performance wise it was not worth it and there seems to be some concern about bullet stability in the 223 Remington/556 that leads them to worry about endcap strikes. Ive got somewhere north of 1200 rounds through my Optimus with the majority of those being 556 with the 22cal endcap and haven't had any problems. But I wanted to share that with you guys so everyone can be informed and have the latest information. |

Took the Optimus out the range today with my 11.5 SBR and A2 Blast Shield Mount. A couple of points:
1. 11.5" SBRs are really LOUD. It would ring my ears even with muffs on. 2. The SBR with the can was much nicer to shoot. However, I wouldn't want to shoot it without ears. 3. I had little to no change in zero with the can. 4. I burnt my leg with the can while letting the SBR hang on the sling doing pistol transitions. 5. A set of oven mitts are helpful. 6. My 14.5" upper was much nicer to shoot unsuppressed than the 11.5". 7. Double taps were very easy with the can. 8. I like the tube cleaning brushes. 9. Anti-seize is the bomb. |
