Much of what was new for SHOT Show 2020 for Griffin Armament has already been covered by our resident suppressor addict and Editor-in-Chief, Pete. However, Griffin Armament did have something new and shiny at SHOT Show 2020. Their GP-N is a QD suppressor that attaches to an A2 Nato flash hider.

Don’t You Mean Halo? Nope. GP-N

My first thoughts of the GP-N, besides the shiny Captain Phasma or Cylon-esque chrome finish was that it is remarkably similar in concept to the Gemtech Halo. Griffin Armament even referenced the Halo when explaining the GP-N to me.

The mount design is definitely inspired by the Halo but they added some much needed improvements. Four years ago I suppressed my X95 with a Gemtech Halo.

Often the GMT-Halo knurled ring would seize up on the threads of the suppressor. Adding the heat from the suppressor makes it difficult to quickly detach.

This issue has been addressed by Griffin Armament when they designed their GP-N suppressor. Firstly the mount is a single tube running the entire length of the suppressor which will eliminate alignment issues. They also under cut the blast chamber, See the three cut outs? Those act like a relief so gases can escape the flash hider and go forward. Less chance of the mount seizing on the flash hider like the Halo.

Another huge improvement on the GP-N over the Halo is the addition of wrench points on the collar and can.

As I discovered in my suppressed X95 article, the Gemtech Halo knurled ring would be difficult to remove after shooting. Griffin Armament designed their collar to use a castle nut wrench and spanner so you can tighten or loosen the GP-N. Now you don’t have to touch the can to unscrew it.

Griffin Armament claim that the GP-N has new baffle technology and at the ear it measures 135 dB and just 133 dB at the muzzle. The GP-N weights just 17.2 oz and is 6.4″ in length. It will retail for just $595 MSRP. No it will not be chrome. They will coat it like all the rest of their cans, they just wanted a little bling for SHOT Show 2020. Go to their website for more info.

But they already have QD suppressors that use A2 mounts. They’re called the M4SD and the M4SDK and they mount so much quicker and easier than this does. So what is the damn point of this if they already did it and better?

  @Andrew Probably because they also had a Halo-type modular mount laying around for the Optimus: https://wwwDOTgriffinarmamentDOTcom/a2-blast-shield-optimus-a2-mount/

  @Andrew You are not wrong. I use both the HALO and M4SDK regularly. I think the point is probably price, as the SDK is a rather expensive can at ~1K. Also, I think the quickness of mounting certainly merits discussion. The SDK has no depth-stop, so you actually have to fiddle with it in most cases, to hold it in alignment with the BFA groove. I think this is ultimately a plus though, as it makes your mount options actually more diverse. I am of the opinion that quickness of mounting and dismounting is not a huge deal anyway though, so i am maybe the wrong person to comment on that aspect. Just figured I’d share my experiences. Like I said, you’re not wrong, but at the same time, this new suppressor has merit. Especially at only a little more than half the price of the SDK.

  @Dingus M4SDk is $725, and comes with a depth-stop, no fiddling required. I also have one.

  @Andrew Well, shoot. We are learning new things all the time. The SDK I use doesn’t have a depth stop. Maybe a generational difference. Also, last time I priced one at my LGS, his cost was around $900. This was a month or so ago. This stuff has me confused sometimes, I swear.

  @Dingus You mount the overtravel stop between the flash hider and the shims. You can buy them off the website. I think the Griffin Gate Lock muzzle devices come with them. My can came with one.
  BTW, I’ve noticed that its become common lately for A2 flash hiders from a variety of brands to be too large to fit. The ones from Wilson Combat work well.

  @Andrew I see! That would indeed increase the speed of installation. Thanks for the WC tip.

  @Andrew All their A2 devices - FlashComp, Hammer Comp etc - come with the overtravel stop now.

  @Andrew The SDQD lineup are not as generous in their ability to take all the odd dimensioned A2 mounts like the GP-N. The GP-N territory is taking all the bastard mounts that would trouble the SDQD stuff, and getting it done in style with the best sound suppression this market segment has ever seen.

  @int19h They always did have an overtravel stop from the M4SD II forward, the M4SD only took A2 devices and had an A2 length stop internally so it never needed one.

  @Austin It would be cool if y’all sold some regular A2’s. I’m probably all set at this point, but it took some experimenting. It would also be cool if y’all worked deals with other manufacturers, such as White Sound Defense (who might be more interested than you think) and Forward Controls Design (also might be more interested than you expect) to make in-spec devices. Dead Air is doing it with FCD and JMac, so its not that far fetched.

I did not realize that the A2 flash hider was NATO.

  @Jeremiah The A1 and A2 are within NATO specs for firing NATO rifle grenades, like most other NATO rifles, but I don't think this suppressor will fit on most other NATO flash hiders.

  @Kivaari Needs A2 length, .860-.864 diameter, .112-.130" groove width of A2 nato print for compatibility. So BCM's gunfighter A2 style and others will probably work.

  @Austin The A1 should be just fine. The old three prong probably not. I remember seeing M16A1s fitted with Energa grenades. I think they also added a copper plated coil spring to the groove so it wouldn't just fall off.
