i CAN HAS explanation

The problem is that some systems require more back (or directed) pressure than others to function properly... ie 7.5 inch vs 20 INCH
Its not a problem of giving it too much pressure, its a problem of giving ti enough to be reliable and in this case avoiding cycling issues...

:p I am lost!

Pressure is just a measure of force per section area - it is the amount of energy transfers that matter - ie volumetric flow.

If a system is calibrated with a certain volumetric flow (fixed gas port size with a specific port pressure - time of pressurization is fixed by the distance between gas port and muzzle), increasing the pressurization period means increasing the total volumetric flow and dumping excessive energy in the system.

Unless any of the 3 variables is wrong in the first place (gas port size, distance between muzzle and gas port and the pressure produced by the ammunition), increasing the pressurization period does nothing, nor does increasing the pressure.

In fact, if the device does increase the port pressure, it will lead to hyper extraction because it will be increasing the volumetric flow rate and duming energy into the system faster than it is originally designed to.

I hope I still remember enough of my fluid mechanics to get this right!
 
Would love to see some photos of your prototype.

Now that's looks slick. Depending on the design/materials used it would appear the mass with the additional flutes may be greater than the pig.

Not being a manufacturer I was thinking as well, if I were a business person, what one could do to modify the design to create a premium line to chisel out some market share. Based on reading feedback from some whose wrists are a bit sensitve to the extra fraction of an ounce a pig adds to the barrel over a conventional flash hider perhaps an offering in titanium? Another thought was as these were designed for SBR's and close proximity work so perhaps an offering with an aggressive leading edge/glass breaker akin to what has been availible on flash hiders and flashlight bezels as of late.

If you use one of the ideas I'd be willing to field test a pre-production version for you :D

The dwell time of the pressure spike definately has an effect on the bolt carrier velocity. Suppressors typically increase the cyclic rate of full autos.

I don't think the suppressor increases the pressure, only the length of time the pressure acts on the system.

Looking at it from a conservation of momentum point of view, if the length of the force (= P dA) impulse changes the magnitude must necessarily change if the total momentum change is to remain the same (and I don't see why it would change). This is from force = dp/dt.

GT - you think your fluid mechanics is hazy... I'm taking the course right now and I'm even more confused! :p

I gotta get off this damn site... lab report due at midnight.
 
In watching the MagPul video Tactical Carbine, It was said that it was best for CQC/CQB so if there was a team member beside you also engaged in combat the sound and flash from your gun would not distract them when returning fire if you are using the Noveske KX3.. Does this make sense?

Going above the pressure and the pressure application time is not BAD thing up to a certain level. It permits for one, the fact that if the system is corrupted by dirt, the stick still works... Opposite to a tighter toleranced and tuned system where powder residue of .5 gms means hickup...

what kind of tooling / manufacturing process do you use for the internal flutes?
Click to expand...

The entire thing is CNC machined.

We had a customer in today examining the prototype who was impressed at how light this brake is. I guess weight is all in your expectations.

Certainly, if you want to pay triple the price, we'd be happy to make it in titanium.
 
PWS makes their CQB Comp which was specifically designed for short barrel AR's and built to direct muzzle blast and sound forward (away from shooter and "team members" instead of sideways and rearward, as is the case with many other muzzle devices...

As quoted from their website...
The CQB Comp, originally designed as part of the Diablo Upper, is designed to provide as much compensation as possible while suppressing flash and sending all the blast forward of the shooter and those next to the shooter.

The CQB comp is designed for just that - CQB. This product comes by request of those running through buildings that love the FSC556, but the blast in that narrow space is too much, especially for the guy standing next to them.

The primary function is to send all the blast forward. The secondary function is to suppress flash and the tertiary function is to compensate the rifle. This product in no way compensates the weapon to the level of the FSC556 or our other comps, but it does serve the needs of those that requested its development.

This unit is 2.8" in length, 1.4" in diameter and is threaded 1/2x28. Weight is 8oz

We've been stocking these for a while...
