Best tactic is to put a drop on the threads near the very end of the thread path near the exposed border of the 2 parts where water can make ingress. |

Originally Posted By Green0: Originally Posted By bmarshall1: I was watching an episode of silence or analytics the other day and I do believe they have a couple of Griffin cans, I'm not sure which model but I'm looking forward and I hope they get a great review I saw a couple of HRT5AM/5K Am cans it seemed with Hubs. I wanted to send the Dual Lok versions so I don't know what happened there. @Green0 I'm think he uses regular hub mounts for ease of changing things around and consistancy. I do recall onetime that he used a Sig mount and that particular mount reduced the Dbs on any can. I also wonder if a mfg stated something like 'this can is much quieter with it's own mount' what he would do. Are Griffin cans more quiet with you mounts and if so which mount makes the most difference, or are we splitting really small hairs. Per Grok: Rob Orgel (Silencer Analytics) prefers and primarily uses HUB mounts rather than whatever proprietary mount a manufacturer ships with the silencer. Key Points from His Content He has repeatedly described himself as a “HUB guy.” He favors the industry-standard 1.375×24 HUB rear for modularity so he can choose his preferred mounting system (most often SilencerCo ASR/Bravo as his go-to QD option). When a suppressor is available in both HUB and proprietary QD versions (e.g., CAT WB Ti), he tests both and has shown measurable differences (especially in backpressure). In those cases he will use the manufacturer’s QD mount for the comparison, but he still defaults to HUB for general testing and personal preference. His testing philosophy emphasizes consistency across hosts and suppressors. Using HUB + a standardized mount (or direct-thread HUB adapter) lets him keep variables more controlled instead of switching to every company’s unique muzzle device/adapter every time. He has noted that proprietary mounts can sometimes perform better in specific metrics, but he still prioritizes HUB for flexibility and does not automatically use the included manufacturer mount for all reviews. Bottom line: He does not simply use whatever mount the manufacturer sends. He strongly prefers HUB and will standardize on it (or a HUB-based system he likes) whenever possible for consistency. He only switches to a manufacturer’s proprietary mount when he is specifically testing the difference between the two versions of the same can. |

I’m real interested in that new Optimus 6 AM. Can’t wait for you to be able to spill the beans on it. Few weeks? I did a thing and ordered a DUAL-LOK Ti Minimalist Brake along with a DUAL-LOK HUB Interface to experiment with. I shouldn’t have done it. I think I’m going to like it. If I like it I’m going to be faced with some pretty monumental decisions. I had zero reason to do it because I’ve never had an issue with all of my Taper Mount stuff and I love that system because of light weight and short length it provides. Not to mention, if I like the DL system, I should’ve bought these latest 4 GA cans with the integral DL interfaces vs HUB.

Thats true. The taper mounts always worked for me and I do like Dual Lok better but not for any great reason given taper mounts never failed me. The Optimus 6 AM cans got welded and heat treated, but we are hoping to get some lead free ammo in before we do test fire. So the hold up is just wanting to keep a test fire booth more clean for the future compliance crap. The ez brake’s kind of square cornered ports would probably not be good geometry for titanium. So to have a ti ez brake would probably ideally involve a redesign of the ez brake not required otherwise. |

| What are the thoughts on the best sacrificial baffle muzzle device on a HUB DL5 AM on a 10.5”5.56 with a Plan A long adapter? I’m looking at the new design hammer comp with the angled slots vs the EZ brake. The hammer comp looks more robust for a sacrificial baffle, and it’s probably better for shooting unsuppressed with if I choose to occasionally do so, but it’s longer, heavier, more expensive, and requires timing. But for shooting unsuppressed, I’ll probably use the Explorr taper mount blast can anyway, so that aspect might not matter. How does the EZ brake stand up to the blast from a 10.5” 5.56? |

The two best brakes Austin seems to always suggest for extending suppressor life are first, the EZ-Brake, second the Minimalist Brake. With an open FH being the worst for the suppressor (opposite end of the spectrum) or direct thread. Anything outside of those is probably an in-between crapshoot. The shorter the better. Or, buy what you want and just shoot it. Put this new 625X stuff to the test!  I seem to be buying new cans faster than any serious erosion is occurring, short of my early days SiCo stuff. |

The hammer comp protection is intermediate between flash suppressor and EZ brake. The sound (on a meter even) is near identical for both. The 625x has very high solid solution strengthening, and mc carbides which resist erosion extremely well. In other words its like a super alloy that is extra super within the family of nickel super alloys. So the material makes 718 look like an inferior material as it pertains to sound suppressors. 625x remains harder at higher temperatures also than 718, which contributes to this more wear resistant result. This is a great material for running whatever muzzle device you want. |

I was mainly asking about the muzzle devices, which are made of regular stainless steel, standing up to short barrels when being used as a sacrificial baffle. The muzzle devices of the best suppressors made are typically 17-4 or 15-5 which are two near identical composition materials. The reason that works, is that the barrel soaks the heat from the muzzle device. The muzzle device is usually below 900F in 17-4 has very high wear resistance. The suppressor baffle application is different- localized heat at apertures gets very high- like 1500F. That extra temperature at the bore apertures of the suppressor is why superalloys get used in suppressors. If a barrel gets much over 1000F, it is being destroyed. I've not seen eroded muzzle devices machined from 17-4. We ran 600rounds cyclic (like in 50 seconds) on a M240 with a 17-4 flash hider and the 17-4 flash hider was fine, and we have maybe 6500 rounds on that flash suppressor in that application and it is serviceable. Obviously that's the type of application that is most likely to see upgrade material if the use case is severe enough. |

Last time ai called CS (a month or so ago) they said there were no plans to spin down the TM products. Of course that doesn’t mean they wouldn’t come out with a new line of mount - like a TM 2.0 or something. |

This is a great material for running whatever muzzle device you want. Without overthinking this....EZ Brake for a SBR and flash suppressor for a 14.5/16? Is there enough benefit to the brake on the SBR or will it not matter much? I am loving this HRT AM with the dual lock and need to pick up two more muzzle devices....one for an SBR and one for a 14.5 |

It hasn't been remotely considered. They are more affordable than Dual Lok and they work well. |

It still reduces flash well on 14.5 and longer barrels. But there isn't a heavy erosion threat from those barrels either. So it's good territory to do whatever you want. |

Gonna be awhile because Im covered up with work. Im sure someone will beat me to it. I have rc2 , mini 2 , DL hrt gen2 and 2 dual lok 5 to compare. |

One thing I noticed, in the part of the video showing thermal was the Griffin can sounded like someone beating a bass drum in the background with the shot, the Laz sounded like someone hitting a sheet of plywood with a hammer. I know Austin commented several times how 'nice' the can sounds, but the back to back lets one hear the difference. Also fairly shocked a the flash signature of the Laz @Green0 - I know over the net it's hard to judge shots, but are you using hi quality microphones for the video portion and is what we hear over headphones fairly accurate (no clipping, compression, etc...) >Off to read the rest of the thread. |

Shooting the Lazarus 6 near the time it came out the impressive part is the peak ear performance for being kind of low pressure- it had peak better numbers than like the CRS-PRT (not 2 or 3 but the first one). To hear them, the Laz 6 didn't sound good to me. It sounded pretty loud indoor. The Dual Lok 5 sounds good inside. Our mic on the camera is pretty good, but being indoor isn't the greatest for hearing the cans on a video with a boom mic. I've been so kind of buried in work I never have heard the can outside, but I'd imagine it sounds really great outdoors, because every can sounds better outside.  First shots with the @GriffinArmamentOfficial dual-lok 5 suppressor!!  Griffin Armament Mk2 12.5 - First Impressions |
