It cushions the end of the forward stroke of the bolt, where the spring would completely compress. It would make the shot smoother, less kick, probably quieter.

Hey how loose should the spacer be on the Axe bolt guide? Mine can move about a millimeter. When I put it on my Mini it didn't move whatsoever.
that's pretty normal - you can see the difference in the bolt guides where the mini's bumper groove is at a 90 degree angle and the axe has been cut at a 45 degree angle. I don't know if Simon did this intentionally to hate on me

Yeah +- 1mm isn't bad I was just making sure it was normal. Wonder if you could rework the spacer to accept the angle. Don't think it's too big of a deal though.
Note: I'm not experienced with this stuff and never tuned with upgrades.
Received my order yesterday. Today I got to test it out. Shot with the stock barrel and then changed over to the Lurker .678 barrel to underbore using cheap Valken Redemption paint (around .68), went from 270ish fps to over 300. Then installed the bolt using a tank o-ring, which was a lot easier than the o-ring that came with it. Spacer seems to fit nice and snug. A little give, which is apparently normal for the Axe due to bolt guide design.
Lubed everything up with Lurker lube (smells like bananas) and took my pressure down to 170 and dwell to 2 blinks (3.5ms on the Shockwave board), and 1 turn on the back cap. Shot around 265 +/- 7 with a couple outliers. Tried to find the sweet spot at a little under 1 and half turn on the back cap. Lowered pressure to 155 and shot around my target fps of 280 +/- 7 with one or two outliers every dozen or so shots (260s and 290s, and upper 240 if firing fast).
Time to install and lube bolt: 5 mins after I decided to use a tank o-ring.
Time to fine tune: 15 mins
I always thought my stock Axe was somewhat loud. Now, it's very quiet. The sound of the balls moving around as my Rotor is loading almost drowns out the sound of my shots. Didn't have the spring spacer with my order, so I can't comment on that. Still have to field test it of course, but so far so good. Like I said before, I'm not at all familiar with tuning and I'm not entirely sure what I should be looking for as far as the "perfect" setting goes. I just followed the directions on the site. There is noticeable kick, I'm guessing I should be increasing my dwell and decreasing my pressure?
The goal (at least for me) is to run the lowest possible pressure. Low PSI = smoother shot.
I can't seem to get mine right. I try some of the settings on here and it just doesn't sound right. I shot a few balls out (I'm at an apartment so can't exactly w/o being sketchy) and it just didn't seem like it was reaching a good FPS.
I'm playing tomorrow and really don't want to tune it at the field with a chrono. What is a good setting I can set it to and it'll work fine? I tried setting it to 4ms dwell and 160 psi like Lurker said but it still didn't seem to cycle correctly.
There's no real answer to that. Every gun has it's own quirks and needs it's own tuning process to settle it in at a nice FPS... and when I say "every gun", I mean each individual one. You have to experiment with different settings until you find one that has the right amount of smoothness and FPS that you're satisfied with.
It sounds like you have a good starting point now. I would try dropping your PSI to around 140 and raising dwell to compensate for the FPS drop.

I'm at 160 psi and 4 ms dwell (16 clicks) and the ball doesn't even make it through the barrel. I even just relubed and reset the spacer.
1 1/2 turns out from all the way in on velocity adjuster.

Here, try the tuning guide, it might help. I honestly don't know why it isn't stickied yet.
If I have time at the chrono tomorrow I will. Since the orings on mine probably still need to be broke in I'm going to keep it at 5ms and 160. Then tomorrow I'll likely just adjust with back cap.
Once I've had a few cases for it I'll retune it. Sound like a legit idea?
