I’m no stranger to Griffin Armament. I just lately reviewed one in all their scopes, an LPVO in 1-8×24. That scope is well-built and sits atop one in all my prized rifles.
The corporate makes many merchandise… for instance, they despatched me a set of AR iron sights and two mounts for a yet-to-ship prism sight. Extra on these will comply with after that sight is available in.
Now that the $200 tax on suppressors is however a tortured dream, each firm appears to be promoting cans… some are higher than others. Griffin Armament is a significant participant on this sport.
So, what I wish to write about at the moment is their suppressor line. (Or, as they name them, Silencers. The opposite shoe drops…).
Seventy-Six
I attempted to consider a intelligent method to say that they make 76 totally different fashions of suppressors, however all I got here up with was one thing about “76 trombones main the massive parade”… sorry…. That’s the band director in me popping out.
Griffin makes all these suppressors utilizing two manufacturing strategies: additive and traditional. Standard, I’m accustomed to, and I’m turning into extra so with additive… substitute “3D printing” for additive.
At any fee, 76 is a heck of numerous suppressors. They’ve suppressors for a lot of calibers and plenty of budgets. Calibers embody:
.22 (rimfire)
5.56mm
7.62 (.30)
.32 ACP
.36 (9mm)
.45
.46
6mm
Supplies that these cans are constructed from embody:
17-4 H900 Stainless Metal
7075-T6 Aluminum
718 Inconel
Nickel 625X
A Bit Of Metallurgy
I believe a phrase about a few of the above alloys is so as, since a suppressor is just nearly as good because the metallic it’s comprised of.
Stainless-steel and aluminum, we’re accustomed to. The aluminum right here is aircraft-grade, and the 17-4 stainless was initially developed for the aerospace trade, as was Inconel. I’m not schooled on the underside two alloys, although, so I learn the blurb on Griffin Armament’s internet web page regarding them. It’s centered on Nickel 625X however discusses different alloys, as nicely. I’ll quote a bit from that web page; put together to geek out…
Nickel 625X is a patent-pending, nickel-based powder superalloy developed particularly for DMLS additive manufacturing processes.
At 1200°F, Nickel 625X™ demonstrates roughly 68% better energy than additively manufactured (SLM/DMLS) INCONEL® 625, which, to the very best of our information, is used within the NGSW suppressors that see service to very excessive temperatures. It additionally reduces warmth remedy prices by ~93% in comparison with the vacuum anneal and age processes sometimes required for superalloys.
Superalloys are inherently dense, so higher-strength choices like Nickel 625X™ allow the design of lighter but equally (or extra) sturdy suppressors. Nickel 625X™ additional provides superior corrosion resistance, with a PREN worth of roughly 57 – considerably increased than INCONEL® 718 (~30), Haynes® 282® (~33), and INCONEL® 625 (~47). Its hardness additionally excels at 41 HRC (in comparison with as-built values of 29 HRC for INCONEL® 625, 33 HRC for INCONEL® 718, and 35 HRC for Haynes® 282®), offering higher resistance to erosive put on of suppressor baffles attributable to high-velocity gases and particulates.
So, we’re wanting principally at a next-generation alloy. Suppressors comprised of 625X are likely to final a really very long time.
What We Have Right here
I used to be despatched two suppressors to attempt… one for a .22 rimfire, and one for a .30-caliber rifle. Right here they’re:
Checkmate AM-22
This $371 rimfire can is on the decrease finish of the value spectrum, but it surely works very nicely. It’ll find yourself on my new Ruger 10/22’s threaded barrel as quickly because it will get right here. Within the meantime. I caught it on an unlikely candidate… my Trailblazer Firearms LifeCard.
This little man suits simply into one in all its leather-based wallets, in your pocket or purse. It folds up and isn’t a lot bigger than an Altoid field… minus the suppressor, in fact.
Sporting the can, the LifeCard turns into a little bit extra unwieldy. However, as my suppressor seller, Peyton Clark from Fortunate Labs Armory found, it will make an awesome little .22 to have with you whilst you have been out working your traps or in any other case within the wild. Stoked with standard-velocity or subsonic ammo, the shot is barely audible and positively wouldn’t upset nature (or the neighbors).
By the way in which, if you happen to reside within the Hoosier state and are available in the market for a suppressor, Peyton ought to be your first cease. He runs a whole store, may be very educated, and has good costs. He can repair you up if you happen to’re an Indiana resident. Name him at 812-554-0624.

I additionally obtained an Explorr 300 Taper Mount AM suppressor.
As I’m discovering out, as I begin on my suppressor journey, some are simpler to connect to barrels than others. I’m studying about them, and nonetheless don’t know what I’ll want to connect Can A to Gun B. The great half is, with this suppressor, you get what you want proper within the field. It features a 5/8×24 mount.
Manufactured from Nickel 625X, this will is light-weight and sturdy. I mounted it on a Ruger Scout .308 bolt rifle. It’s designed for each bolt and fuel gun use, in contrast to many fashions.

Decibel Reductions
I wish to faux that I’m a scientist typically… even have the lab coat. (Not likely…)
I used to be interested in measurable noise discount, so I grabbed my trusty noise measurement machine – my iPhone – and opened one of many decibel apps I’d put in. It’s not precisely sound-meter high quality, however it can give us an thought of how a lot sound is lowered.
To assessment, decibels measure sound depth on a logarithmic, not linear, scale. So, a 10-dB increase isn’t just ten instances extra, it’s 100 instances extra.
Right here’s a fast reference chart of on a regular basis sounds and their dB ranges…
0 The softest sound an individual can hear with regular listening to.
10 regular respiration.
20 whispering at 5 ft.
30 gentle whisper.
50 rainfall.
60 regular dialog.
110 shouting in ear.
120 thunder.
Science class is over. Now, for the cans…
I positioned the Checkmate on my LifeCard single-shot .22. I did this for 2 causes. First, the gun is novel… verify my linked assessment for particulars. Secondly, the barrel is extraordinarily quick, and shorter barrels are often louder barrels. I believed the can would have its work reduce out for it. I didn’t even use subsonic ammo… simply atypical standard-velocity Fiocchi Vary Dynamics, rated at 1050 fps. (As I discussed above, I might be receiving a threaded barrel from Ruger for the ten/22 I simply reviewed, and can do an replace.)
For the Explorr 300, I connected it to my Ruger Scout .308. Once more, this rifle makes use of a shorter-than-normal barrel for the caliber, so I believed that could be a very good take a look at. I shot some Black Hills 155-grain ELD Match ammo, the primary Black Hills field I grabbed.
For the Checkmate, I acquired these averages:
Non-Suppressed Noise Degree: 106.4 dB
Suppressed: 83.6 dB
And, for the Explorr 300:
Non-Suppressed Noise Degree: 117.8 dB
Suppressed: 103.6 dB
The .22 confirmed a median discount of twenty-two.8 dB, whereas the .308 averaged 14.2 dB. The LifeCard exhibited a quiet “pop”, about like a gentle pellet gun, whereas the Ruger sounded about like a .22 Magnum fired from a 6-inch revolver. My brother-in-law was capturing the LifeCard, and after the primary shot, his eyes acquired large… he couldn’t imagine how quiet it was.
That’s sufficient noise suppression to warrant the acquisition of a suppressor. I put on listening to aids, partly because of my age, but in addition because of the truth that I shot numerous weapons and listened to numerous loud music in my misspent youth. The great half about these suppressors is that my listening to, or what’s left of it, might be protected. I nonetheless advocate sporting listening to protectors, however that’s your name.
Abstract
Griffin Armament produces an entire lot of shooting-related objects. I discussed earlier, a scope, a prism sight, and open AR sights, and we checked out a few their suppressors. If you’re wanting so as to add a can to your pistol or rifle, you may wish to give them a glance. With the elimination of the $200 tax on suppressors, evidently all people and their brother is making them. Please make sure that you’re getting your cash’s value… with Griffin, that’s not a problem. These cans will final, little question.
Additionally, let me put a very good phrase in for Peyton Clark, Fortunate Lab Armory (hyperlink above). For those who reside in Indiana, he can repair you up with nearly any kind of suppressor (or rifle) you’d like. He’s acquired an awesome inventory, and he’s an awesome man. He’ll deal with you proper.
