The baseline graphs look like two different platforms. Perhaps a new one and one that has broken in more, or one dry and dirty and one cleaned and lubed. There appears to be both a different sampling rate and post sampling hardware and/or software filtering and/or simple averaging. While they mainly impact finer data range transitions, I was trying to reverse the graphical point coordinates and crunch them to sum the area of the positive pulses and the negative pulses to compare for an overall quality factor as well as the individual big events that are caught. It's all very cool technology to play with and draw conclusions from. Imagine what the big boys have at their disposal? I spent 15 years in Aerospace Test Engineering with random and linear vibe generators, transducers, environmental chambers, etc. We had to test and documented product performance (or failure) for Navy fighter jet computers, air to air missile computers and radar targeting computers for the 20mm Phalanx System and it was a ton of fun. Broke my heart to get "workforce reduced" after 15 years so the company could make a quarterly profit statement. They didn't last much longer though, but it was still stressful re-entering the labor market at age 42. Hoot yet again digresses....![]()
All that having been said, you don't need to crunch the raw data mathematically (though it would be nice) to visualize the change of period of the first recoil pulse due to the added weight in the bolt, or it's effect on bolt bounce as well as smaller nuance changes.
From your experience so far, is it more maddening to try and A) optimize each of the finite elements such as the brake, optimum carrier (or buffer) mass, buffer spring weight and active delay line stock individually for their impact upon recoil and then try to merge their characteristics, or to B) try them all lumped together and then optimize each one's characteristic for the ultimate good of the combined package's resulting trace, or is it more A) first, B) second, back to A) then B), etc?

Looking at the detriments as well as the attribues of the CCWS, it's got me wondering if a gas port move or adjustable gas block (which I have) would be a better choice. I don't think a heavier spring is the solution as it slams the bolt back all the more harder, adding stress to the cases and peening the barrel extension, bolt and cam pin. In retrospect, the heavier carrier while not pushing harder by virtue of the spring, still adds to wear and tear by virtue of momentum derived from the additional mass and it deadens the anti-bounce deadblow design within the buffer. Might be interesting to substitute a glued in mercury filled metal capsule instead of the solid lead slug. Hmmm.... [ http://www.militaryfirearm.com/Forum/images/smilies/03.gif ]

Second would be one of those Wolf or equivalent XP springs compared to the stock A2 spring. I think they would be good additions to all the data we are fortunate to have access to.

I have Enidine, stock and heavy weight buffers for carbine length. Plus stock spring and wolf heavy spring. Would be happy to send em in for the test.

Recieved. Enidine, stock and heavy weight buffers for carbine length. Plus stock spring and wolf heavy spring. The Enidine buffer looks very interesting.
