Most flash hiders are threaded in place, but some may be attached via set screws if the barrel is not threaded. What is a Flash Hider?Ī flash hider or suppressor is a muzzle device which attaches to the end of a rifle barrel. The muzzle device has been maligned to the point of being outright banned in some jurisdictions, with some versions tightly restricted by the Federal Government. I'm sure I'm not the only guy wanting to put a flash hider mount onto an AR instead of a brake in case I shoot it unsuppressed, and I want to know if it really will matter.If there ever was a part of the AR-15 rifle that was grossly misunderstood, it has to be the muzzle device, be it a muzzle brake or a flash hider. I want to know if there is actual science, or even anecdotal experience behind the idea that a brake is the way to go. I think it's probably pretty agreeable that either a brake or flash hider is probably better than just a direct thread adapter. I have to imagine an A2-style flash hider isn't that different from a brake in a certain respect in that the bullet is still sealing the forward path and the gases have to exit the sides, like a brake.
Griffin has some commentary on Brake vs Flash Hider having no tangible effect on sound. What I want to know is if this is actually proven, or if it's just one of those things that sounds like it makes sense so we all just keep repeating it. I know that brakes are considered to be the way to go as a suppressor mount because, in theory, they're a sacrificial baffle, and they help with the initial expansion inside the expansion chamber. I have no idea how true this is, however their cans are exceptionally quiet, and the mounting system is good. The brake ports are offset by a margin, and apparently induce a spin or cyclone effect. Australia does have its benefits, sometimes. Got a good suppressor design ? I can make and test it REAL fast, as I don't need any FBI tax stamp. I'm a manuf who can make whatever is needed for a job basically, like a SOT2 / 4 I think you call it. It's not law, it's just a policy police try to enforce. As such, they are "unregistered" and stupid police who authorise ranges put in place a "no unlicneced or unregistered firearms" restrictions. I can't shoot mine at a range as I don't register them.
#FLASH HIDER VS MUZZLE BRAKE R6 PROFESSIONAL#
They are for pest control (licenced professional contractors) so they are quite limited. I have no idea how true this is, however their cans are exceptionally quiet, and the mounting system is good.Īlso why I said I used the blackhawk style originally, as it was a good brake anyway.Īs for Aussie laws, we don't pay rego fees to register them, so no tax stamps. I don't know the exact science behind overcoming this but apparently more than a few manufacturers have figured it out.Ĭlick to expand.The brake ports are offset by a margin, and apparently induce a spin or cyclone effect. When the bullet and hot gas displaces that ambient air inside of the suppressor is when you get FRP. I have always heard it's more of a function of the suppressor design. Overall though this type of stuff is so far out in the weeds it's not worth chasing.Īs far as FRP goes I am all ears. Of course that is within reasonable limitations. My experience leads me to think the difference would be so small it would be easily overcome by a different brand or lot of ammo or even the weather outside being different on a given day thus rendering 'muzzle device type' to be less of a concern. Usually people making this claim say it's because bigger muzzle devices take up more space thus reducing the volume inside of the can. You can either get it re-cored or just buy another can if you are shooting that much.Īs far as sound reduction there are also 'theories' that different muzzle devices inside of cans cause more or less sound reduction. If you shoot enough to wear out a suppressor your budget is a lot bigger than mine. While there may be some truth to it I am not aware that any definitive evidence has been shown to conclusively prove it. Some people have floated the idea that certain types of muzzle devices will absorb the brunt of those abrasive blasts thus extending the life of the suppressor. If you shoot an insane amount of rounds or shoot select fire, depending on the baffle material the blast baffle itself will erode and degrade the sound performance of a suppressor. The concept is that when a round goes off you have super heated gas with particulate blasting forward like a mini sand blaster. Silencer Shop has come out more than several times on their YouTube channel and said exactly that.Įven if you accept the theory about 'sacrificial baffles' that has just about zero impact on sound reduction. Click to expand.I have heard lots of theories on this sacrificial baffle thing and in several podcasts numerous different manufacturers have cast doubt on this claim.
