I'd bet that the compensating effect is more valuable than the dust sig. But the dust nonsense sells well for aftermarket models like the phantom and such.
Thanks for the reply. I went ahead and grabbed an A1 online and will give it a try. Originally Posted by demigod. At least in a North Carolina beanfield that hasn't been rained on for a month, you'll get a major dust storm with an A2 flashhider from prone.
As I recall from when I had a Colt Sporter Lightweight, about like a with an A2 stock, the owner's manual called that part a "compensator," but it never paid me anything so I don't know why they called it that. I guess when you think about it, the amount of muzzle gas that goes through the flashhider slots is very small compared to the amount of gas that fans out straight ahead.
Maybe a suppressor would help a lot, but not a flashhider. The next flash hider to consider is known as the Vortex. The real-deal, actual Vortex is made by Smith Enterprise. As a result, the Vortex does a much better job of turbulating the gas flow of the muzzle blast, thus hiding the flash. Yes, turbulating. It's my book, I get to invent words now and then. The one drawback is that the open ends of the tines can catch on stuff like vines, branches or gear.
Everyone from the smallest machine shop to massive offshore manufacturers has made copies of the Vortex design. So buy original if you can. There are more kinds of flash hiders: ones with slots, drilled holes, ports, vanes, grooves, you name it.
A muzzle brake is a simple thing in theory, and a difficult thing in the real world. A brake directs hot, high-pressure gases, turning the gas flow into something we can use. When the bullet begins to move, the rifle begins to recoil.
The first approximation is muzzle velocity multiplied by mass. For a. The rifle weighs 7. There are 7, grains to a pound. So, our first estimate will be that the rifle will recoil at a velocity of 3. The actual total recoil is derived via calculus, as the bullet does not spend the entire bore time at 3, fps. The same estimate, using a hunting rifle in.
The muzzle blast is basically a jet nozzle, and we can also calculate that. If we take a basic. The hot gases jet out at over 4, fps, in some loads as high as 5, fps.
The only advantage I can see is if you rest your muzzle in the dirt it prevents dirt from getting in the bore.

The M16 had the 3 prong, the M16 A1, which is what I was issued, had the birdcage, the A2 had the birdcage with the closed bottom.
It is well made and nicely finished. Quick Navigation 6. All times are GMT. AR » AR Discussions. Site Notices.
Meyers' New "Pocket Rocket". A2 flash hider. As an improvement over the A1 birdcage, the A2 flash hider has a closed bottom that a. Those enhancements are easy enough to see and appreciate. But from the standpoint of just flash hiding, it seems that the A2's lack of the ventral ports that the A1 has would cause it to actually direct more flash towards the shooter's field of view, thus making it a somewhat less effective flash hider than the A1.
Is this correct? I am aware of the other flash hiders available; my question is really just about the A2 versus the A1. Not really much more flash. I have both and tried it at dusk, could not tell the difference.
