J.P. enterprises original Cooley brake, or a Rolling Thunder from Triangle. Now take this for what it is worth.. Rene Peltokoski...the current world rifle champion and I agree! As long as you are used to what ever you are using, it doesn't matter what you use!!!! In the immortal words of my amigo Jake Kempton....R.I.P. if it is at the end of the barrel on a 223 and it has fairly large holes it is going to work! To be honest I can make almost any neutral brake work form a Michulek to a Lantak in less than 500 rounds by adjusting my hand position in off hand......the rest doesn't even matter as

AR-15 barrel length, gas operation/tubing, recoil discussion

The "gas" isn't a gas is what I am saying. It is gas with solids, particulates, and liquids all flowing together, made up of all sorts of chemical compounds. So looking at perceived "gas" charts based on a pure gas.....not a plasma, don't give an accurate rendition of what is happening......and yes pig tails help, but once again, with feeling, the closer you are to the chamber with your "gas" port, the higher your "gas" velocity, the more violent/faster the carrier reacts. -

Gas, in this case, is quite a misnomer. The "gas" from a modern propellant acts more like a plasma. Which at higher pressures is not very compressible. Constricting a plasma increases it's velocity.....much like the garden hose analogy, but does not drop the volume like it would if it were a "gas". It still effects volume to some degree, but what you are doing in reality is increasing the velocity of the plasma in the same space as before i.e. gas tube volume, bolt carrier volume, etc. More plasma velocity equals quicker carrier reaction. Yes you can constrict the plasma to a point that it doe -

Maybe the laws of physics has some input on this. Calling Mr. Boyle? -

Restriction does not decrease pressure. The closer you are to the chamber the higher the pressure. -
Shadow great! Bullets forward for me.

Im saying that they are spotty right out of the box. Some are great some are not without some work. The box, however, is of a very consitsent size and capacity. The graphics are very precisely placed it closes every time and opens easily. The springs never wear out because it doesn't need them and you don't have to cut, polish, nor port, to use it to hold the originalc contents......yeah......the box.

This might be a good question to ask proof research.

Practical port work??? I think those words don't mean what you think they do!!!!

My top fuel drag car would occasionally choke on regular 87 octane gas......matter of fact it ran down right poorly, but I had a lot of 87 octane gas, so I switched to an engine from a stock Honda civic and have been happy ever since!.....well I'm not placing that well, but hey!!! Pump Gas!!! -
I got one drilled it all out, did all the tricks and I can't say it was any better than what I started with. With all the hype I was expecting at least some improvement, but maybe it just isn't cut out for 458 SOCOM.

There have been historical records of very happy Edsel owners as well.
