We all know the ups and downs of muzzle breaks. The better the break is at reducing recoil
the louder it is. The quieter it is the less braking it does.
Having dealt with the 50 bmg and other large cartriges there is another element that has to be
dealt with, Pressure wave/concussion (Muzzle blast) from huge amounts of pressure and
volumes of gasses at super sonic speeds exiting the muzzle.
So not being one to leave things alone I decided to try a new concept/theory and use the Barrett
M82 A1 50 bmg as a test bed because it is recoil operated and would not rely on perception of
The existing break on the Barrett does a good job of making the recoil reasonable but it has a
terrible muzzle report that requires ear plugs and ear muffs to protect your ears and sinuses.
The snipers report that after 30 or 40 rounds they had some cases of nose bleeding from the
pressure wave and that if you try to shoot it with only ear plugs it was known to blow them
out of your ears from the pressure inside of the sinuses.
The goal of the prototype was to end up with close to the same volume of the ports as the factory
and see if the new design could compete or improve the recoil reduction while reducing the
pressure wave and signature of the big 50 bmg.
I talked to several muzzle brake
manufactures to find out there opinions on the breaks they make
and the performance of them. Jim See has a great break and I knew it would be tough to beat it
or even match it in recoil reduction. (I still don't know because I have not tested a small version of
the prototype break).
So the new design has progressive ports,(Each port has a greater angle as they get farther away
from the muzzle) In theory, as each port is opened up the pressure drops and the next port is less
efficient as far as recoil reduction. So by increasing the angle they will contribute more/equal to the
past port making it more efficient.
Also the design of the ports are an attempt at moving or minimizing the pressure wave away
from the shooter.
After the initial test I am very pleased with the break and intend to produce some smaller ones
for testing on 30 cals and 338s. we will see where that leads.
You can find the test on You Tube Under http.//www.youtube.com/watch?v=20 pG5euY3s
Or if the link doesen't work, just look at YouTube and look for Barret M82 A1 .50 cal prototype
Thanks: and I hope all of this theory is not to boring.
More to come.
