Calling on AO

[Butterfingers]

could sombody generously post a pic of this waveform for me.

How many shots do you see...

sounds like a motor dosent it :)

[krafty]

The computer I'm at won't let me do a picture of it, but I took the 1st second of it and blew it up in Cool Edit. 20 pulses. Looked VERY evenly spaced out, too.

[Load SM5]

Did you have Taco Bell for lunch? That was gross.

[shartley]

Here is a Cool Edit Pro shot... yup... 20. Count them.

[Butterfingers]

avg peak amplitudes are the same too... you know what that suggests... no shootdown YAY!

[BTAutoMag]

wow that sounds pretty cool.

[shartley]

Yes, VERY consistent. I am impressed... not so with the other claim made here on AO... I posted a shot of that as well...

But hey, even at 14-15BPS that is still fast for those other guys. Their claims however, or 22BPS are unsupported.

[wyn1370]

but they are doing it on a semi. unlike the emagnum on full auto. that's why the emag has nice evenly spaced pulses. I'm not claiming I believe the other guys, but it's still darn impressive.

[synreal]

looks like 20.5bps to me

i'm guessing the secondary peak is the bolt reseting/sear catching.

[shartley]

Go read the other thread. Like I said, even at 15BPS it is impressive... but to claim double shots per spike? I just don't see it. Also to claim 22BPS in semi? LOL 15BPS is impressive in Semi.. even in FULL.. they should have left it at that....

[wyn1370]

yeah I read the other thread, just couldn't decide which one I was going to reply to. guess I should have picked the other one.

[synreal]

impressive, you bet....22bps..nope

i count 15bps (which is still VERY nice)

Darnit you caught us

Yes that is most likely the bolt resetting. Its about 2/5 of the way down so seems consistent with the 20 MS cycle time quoted.

When we get L10 installed whenever it comes out ill post another waveform so you guys can figure out if L10 is faster or slower than the original.

You guys are really gonna have a hard time when we get the e-magnum to break the sound barrier... LOL JK.

[Butterfingers]

This is also a testament to the time and inginuity AGD put into the RT valve system. Would you guys beleive me if I told you that this wav was created on a gun using a simple Nitro Duck screw in HPA system outputting 780psi @ 2000psi at the time of testing.

How about if I told you the tank dropped off around 80 psi @20bps so the gun was only seeing around 700psi and as you can see the RT valve system stayed consistent.

I wouldent be surprised if the valve system exceeds its claims.

20bps without shootdown PSFT! yeah right, AGD stop underrating your guns!

[Vegeta]

lets say on average the bolt moves .75 inches every cycle... at 20 bps, that means the bolt it traveleing on average of 122.72 miles per hour...

If the bolt was to break the sound barrier, that would mean we would have to shoot at 114.07 cycles per second.

Here is the math if you wanna see how i got that:
.75 (bolt travel) x 20 (cps) x 12 (inches in a foot) / 5280 (feet in a mile) x 60 (seconds in a minute) x 60 (minutes in an hour) = 122.7272727272... Miles Per Hour.

to find the latter:
700 mph (est. avg. speed of sound) / 60 /60 x 5280 / 12 / .75 = 114.07 cycles per second.
its just reverse.


pretty cool huh!
