Flash hiders are illegal in the USA but a muzzle
brake is made to stop- barrel lift on discharge this allows for quicker second
shots. What it does is to hold the barrel down using the hot gases as they exit
the barrel to help defeat barrel lift on discharge. Many years ago as a boy when
buying some fishing supplies I wanted a particular lure which was quite impressive
looking. My uncle said Richard that lure was meant to catch a fisherman and not
a fish. Undaunted I took my allowance and bought it and my uncle was right it
had caught a fisherman, “me” and though I had used it many times I never caught
a fish with it. Muzzle brakes are probably about like that. Some cost a small
fortune but outside of looking good I do not think they are worth the money
spent on the pretty things and it looks like very little science was involved.
An “OK” AR muzzle brake will expel the gas at the top and the sides and the bottom
is solid and so the upward exiting gasses will push against the flat bottom
holding the barrel down. Some of these come with a crush washer on eBay for
about $10. If you need a phallic symbol (symbol of your manhood) that may do nothing other than look pretty spend $100. The pretty muzzle brakes will do no more than waste your money
A crush washer will
not un-crush so to keep from turning the muzzle brake to far do as described
below and by eye line up the paper with the front sight so the paper makes an upside down "T".
In a war a simplistic flash hider
would be a piece of thin walled pipe that would go over the muzzle break The
pipe would have a lot of holes drilled in it to let off the gases and an exit hole large enough to let
the bullet out with room to spare. This is very close to some military designs.
