Hi @Green0 ! So I have multiples of these 3 (I have many more GA cans, but my scope concerns these models): non-AM taper mount: Recce 5K EXPLORR 224 EXPLORR 300 I freakin’ love the above cans. Workhorses and they handle all of my absuses. My question is, if I were to buy the updated AM versions of each of these 3 cans (I’d order all 3) what would my expectations be vs the 2-4 year old non-AM versions I have? -Besides minor weight increases, would I notice any better sound reduction performance? (Your specs seem to indicate approx 3db quieter on the AM versions, apples to apples) -Would I notice any back-pressure / flow-through differences? -Heat time / cool time differences? Thanks and appreciate all you do! |

I want to be conservative so realistic expectations get set. I also can say I haven’t shot the cans outside head to head or indoor head to head to be able to really speak to same day comparisons so rather I’m in the group where I would have to pull down a memory of one versus the other and thats the context I’ld be speaking in here. The last Recce 5k model with the 718 blast baffle, I really liked. I think the new one performs pretty similarly to it. The sound meter says better 2-4 db at every location. We reduced flash signature also. I don’t really recommend replacing them all, I would think of those more like similar human tangible performance cans that improve durability and flash reduction more than any other tangible things. Out of that group probably the Recce 5K Am makes the most sense as a can to potentially own for a person that already has and likes the cans you have. If you want to have a more tangible improved experience I would recommend either a HRT5 or a Dual Lok 5 if the emphasis is on sound more than backpressure reduction. These cans add more different performance advantages and get into the “generational change” camp. For example the recce 5k non am model might be 139db muzzle on an 11.5” or something like that. The DL5 is 129db muzzle on the included ez brake mount. That 10DB change is huge. That hits like a two by four to the head in so far as how obviously better that is. |

The HRT556 AM is a really nice can. It performs with cans up to twice the price. In its form factor, it's in a very small part of the market with the best products that exist. The DL7AM is a great can too- 119DB in 300BLK subsonic, that's the kind of performance people want in a can. |

The DL7AM is a great can too- 119DB in 300BLK subsonic, that's the kind of performance people want in a can. Looking forward to it! The DL7AM seems to have serious noise reduction and will be significantly lighter than the Velos LBP 762 I was thinking of ordering. I like my Velos LBP 556, but I think I’m going to like my HRT556AM a lot more, not to mention the cost differences in these cans. Those Velos cans are fat, heavy beasts and you can really feel them hanging off the front of your rifle. 300BLK subs and supers will be very cool with the DL7AM. Can’t wait. I’ll probably still stick to my EXPLORR 300 TM for my hunting 308 as I don’t need to worry about rapid fire / heat there. Weight and agility is the huge priority when hoofing around the woods. Unless you can convince me I need an EXPLORR 300 AM, lol. Thanks again Austin for all of your critical comms and participation in the forums. So many reasons to go with GA products. |

No really compelling reason to replace the EX300 with a similar can when you have other cans for harder higher round count use. We aren't so much telling people an EX300 is obsolete as we are trying to move some lathe time to printing in a world where we need to make more cans, and skilled CNC machinists are harder to find. Not to say we didn't improve the can and make it of better material, but more so to be honest with the concept of 17-4 is already good enough for practical use, especially if have a brake mount protecting the blast baffle. |

Ok @Green0 - next question. My Checkmate-HD. Is there any reason to go with a Checkmate-AM22 for primarily 22LLR pistol plinking? Occasional mag dumps. Do you lose the serviceability with the AM22? |
|
The AM-22 is a quiet can, but in terms of serviceability the Checkmated HD is a longer life option because it can be cleaned. The only thing the AM brings is 16” 5.56 compatibility which only really provides value to new suppressor users who don’t have other cans for that. |

Waiting on just one more to come in - DL5AM - these came in in the last few days. They're works of art @Green0 ! Attached File Attached File |

Thats cool looking forward to hearing your thoughts. The KAC cans are really nice cosmetically. I agree the finish quickly grew on me. Aka I warmed up to it- it offers grip almost half way between smooth and 3m grit tape, which is kind of useful to grip not slipping on the can. We’re trying to compete more with B&T pricing, and that keeps us from really going nuts on cosmetic finish of the cans because additional machining in inconel adds substantial cost. 625x gets machined by specific tough carbide inserts with larger corner radius at ~85sfm (very slow). We tried ceramic but 625x just has too many work hardening and abrasive properties for ceramic- one cut just destroys ceramic inserts seemingly regardless of sfm), so we can’t get the higher speed process benefits of ceramic or sailon inserts. All the content that makes it great for erosion resistance and to an extent its incredible strength, makes it hard to machine. We have a new pistol can coming soon and just cutting a thread on a diameter was a 5 minute operation. Just part of the machining it required. In stainless steel the same thread would be 45 seconds. So 7 times machining cost with inconel between tool wear and additional time. |

I have heard other manufacturers report anywhere from 2-5x lifetime for a printed core compared to a traditional baffle stack that the print was based on. They become, at that point, nearly identical with the main difference being no welds. Fewer points of failure generally leads to less failures. |

Just got all of these out to the range today. Wow! The HRT5AM, HRT5KAM and DL7AM were freakin’ amazing. The DL7AM’s performance compared to an Omega300, 36M, Scythe Ti and EXPLORR 30cal (non-AM) was pretty shocking. I think it’s my new favorite suppressor. Griffin has a winner on their hands for sure. I may be buying a second one shortly. I forgot my new DL5AM today (wasn’t in the range bag when I got to the range, lol.) If its performance is close to what the DL7AM does for 300BLK I’m going to probably buy a second one of those too. If you don’t already own one of these newer Griffin AM cans you need to get one - not joking. This was all with adjustable gas dialed for reliable function unsuppressed - 7 rifles total. |

Thanks for the feedback. It did pretty well at the silencer summit too from what I was able to see of the results at its diameter and length it is the most quiet can muzzle, and the second most quiet ear by about 1DB on each end. This can also has a very performing flash suppressor and is highly durable, whereas I don't know how the other can compares in that camp. It's important to consider length and diameter when looking at results too. We also don't have any geometry designed to shield a 1M muzzle mic from SPL whereas the other can did have such a geometry which can hide a couple DB of sound from the 1M muzzle mic without actually reducing that signature forward of the gun. The pistol cans are quasi-rectangular 625X cans with boosters that are printed and machined into the suppressors. The machining of the booster and threads takes as long as making the booster did previously, but this allows the booster to be massively wear resistant, corrosion resistant material which is nice. The cans are abnormally quiet because they have more volume than cylinder cans and they also have the benefit of the crazy geometry of additive. They are super neat in the pistol can space where everything else is kind of in the same performance bracket. |

Thanks @Green0 - still can't talk about the new Optimus 6 yet? What is it's purpose in the lineup? Where does it slot between the DL5AM & HRT5AM etc. I know it's a larger diameter unit. That's fine if beans can't get spilled yet. I have a feeling it's going to wreck the Velos LBP 556 (a can I also have and like) with the added volume. |

I have a feeling it's going to wreck the Velos LBP 556 (a can I also have and like) with the added volume. Yeah it will outperform a Velos LBP. It exists because we had an Optimus 6 and wanted to support it in house in the SLM machines. It's place in the lineup is the only 6 ARC carbine can in the lineup, also the lowest flash and backpressure 5.56mm option. We intentionally didn't take full sound performance advantage of the volume, giving about 17% of system length to the flash suppressor system, because we didn't see the point of lowering the sound much more, and targeted further reducing the muzzle flash over obtaining greater sound reduction. The can is pretty similar to the HRT5. It is ~1.5DB more quiet muzzle, approximately identical to +1DB ear (larger 6 Arc bore relationship here), and has about 40% lower flash signature (in 5.56mm), and lower backpressure and bolt speed. I don't know much about 6 arc can options on the market (I have seen little data and have only run the Laz 6, but I know it outperforms the Havic, and outperforms the Lazarus 6, muzzle, ear, backpressure, flash (basically all metrics). To be honest, at the project end, my only regret was that I didn't make it in a 5.56mm bore because I don't really care about 6 ARC. haha. I get that 6 ARC uses a funny magazine, loses capacity, and adds range, but all combat statistics say that 90% of lethality happens within 300 meters of distance, and urban probably cuts that in half, so the ARC is all about 10% of lethality outside urban environments, and it's a bunch of cost and compromise and nuance to work harder that 10%. Call it a point past diminishing returns. |
