Well yeah, they copied BE Meyer's 249F internally serrated tines.
edit: I did not remember correctly.
This thing was advertised over at TOS. I wonder if it really does what they say? If it did, it would definitely be interesting.

In a comparison by thetruthaboutguns,com - https://www.thetruthaboutguns.com/ar...ider-shootout/ - they said that JP Enterprises agreed to stop production because they agreed it did infringe on the 249F. Yet I still see them advertised.
What is really confusing to me is that the drawing on the installation instructions (follow link at bottom of this page https://www.jprifles.com/buy.php?item=JPFH-556L) shows scallops on the ends of the tines and the inner serrations, yet their advertising pictures show the a different device - refer to the page I linked above and everyplace on the internet.
Anyone know whats up?
Interesting discussion. If I had the option, I'd go FH. For someone who lives in a ban state, where an FH is verboten, what would be the next best thing?
I am curious as to why the Russian's chose more of a hybrid type comp muzzle devices on their newest AK assault rifles. I guess they don't put flash suppression as high as a priority as we do, and are willing to compromise some to get the benefits of a comp. I guess as with most things, not all hyrid comps are created equal.
WRT to FH like the JP, the Smith Vortex, and similar designs: that design tends to produce FH that are the absolute best at flash suppression, one of the few designs that surpass the plain old bird cage.
Even though these designs are a bit better than the A2 at flash suppression, I've avoided them because the ones I tried had the unfortunate side effect of kicking up more dust when shooting prone. In the end, I prefer designs that do flash suppression at least as well as the A2, AND offer additional capability beyond it. An example on the budget end would be the YHM Phantom, for $23, which actually does flash suppression slightly better than the A2. In the mid-range for $50, as stated earlier I prefer the FCD 6315, which does flash suppression as well as the A2, but gives noticeably better muzzle rise compensation--and without any added blast or noise. At the high end, I've never tried a high end dedicated FH but if I did, it would be the White Sound Fossa, which appears on paper and in published tests, to be the closest thing to a well-balanced, multi-purpose device that would appeal to me.
Took a low light pistol class today and brought two of the rifles in case there was free time at the end. Super unscientific because they were different rifles and all I was doing was trying to catch fireballs. KAC 3 prong on a Mod 2 carbine upper had very minimal flash. The BCM comp had more, but to me as the shooter, it was barely noticeable. The only time I actually saw it was on the last two rounds with the FM .223, and I wasn't using my light or aiming at a real target. This is anecdotal, but I shot my RS for the class which obviously has the KKM comp, and I never noticed a flash while firing. My guess is that the fact that I wasn't trying to see it was part of that, so if I was in a real shooting or even just taking a class, I probably wouldn't have noticed the flash. This would be even more true if using the WML. I'm not going to waste the time editing, but I can throw up some videos. I used an older GoPro on my hat and had someone film me with an iPhone X.
I'd still be interested in seeing the video.
This is the playlist of the videos from my phone. The GoPro footage definitely shows more flash so I'll get them up in a bit.

ETA - GoPro footage should be in there too now. Like I said, super unscientific but I expected more flash from the comp and was pleasantly surprised when I didn't notice it.
