BP-Technologies Muzzle Brakes/Compensators

[Patriot_1776]

Anyone tried these before?  They are advertised as having zero increase in muzzle blast, while at the same time reducing recoil and muzzle flip.  How was the report: same as, or less than most other muzzle brakes?

Never tried one but I would be most curious as to how "zero increase" in muzzle blast is defined. I would recommend checking this most closely. The physics of a brake demand that gas generated by the combusting powder be used to develop a reaction force to the recoil. It is this same gas that creates the muzzle blast that so many find objectionable (particularly shooters at adjacent benches).

For a given round, the same amount of gas is developed when the trigger is pulled irrespective of whether a brake is used or not, hence the same potential muzzle blast. So in a technical sense, unless the brake creates more powder combustion, it does not add to muzle blast per se. The key is where the gas is directed or channeled by the brake. If more of the gas is directed outwards and slightly backwards (in order to counteract recoil), the shooter may not notice any increase in muzzle blast but rest assured it will get the attention of the poor bloke at the next bench.

Patriot,

Don't believe their claim of "zero increase in muzzle blast".  They like other muzzle brake makers just redirect the blast away from the shooter which means those around you get the full effect of the increased blast.  They state on their web page http://www.bp-tec.com/info.htm the following;

The VA Comp shown at right uses four separate chambers with four different impacting plates to redirect and channel the intense high pressure found in a discharging cartridge.

The key words here are "redirect and channel the intense high pressure" which shows all they do is to direct the sound away from the shooter.  There is no such thing as a QUIET muzzle brake.  Lawdog

:cb2: Isn't that because there is no such thing as a quiet gun?
