The one aftemarket bolt to rule them all! (Empire Axe)

Hey guys, im looking for a new bolt and four competitors come into play.

Boss bolt (http://www.bosspaintballproducts.com/axe_parts.htm)
Tect DELRIN bolt (http://www.techtpaintball.com/Products.aspx?CAT=3226)
Ndz bolt (http://www.newdesignz.com/InvertMINI.htm)
Lurker bolt (http://www.lurkerpaintball.com/minieigenbolt.html)

So I ask you...Which one is better AND WHY. Please no fanboy posts, the more facts you can state the better.

The Lurker bolt I think is the best because its not just a delrin bolt, but it has a spacer within it too which helps a lot. This makes it have a lighter force for brittle paint and is lighter because of the space cut out for the spacer. The other ones are just Axe bolts that have a derlin construction, nothing else. The only difference is that the Boss bolt is said to have accurate tolerances.

I've only used techt's delrin bolt and lurker's eigenbolt. Currently I'm using lurker's bolt, as it's the best I've come across.
I'm no fanboy, so here are some actual facts about lurker's bolt.
Out of all the bolts available for the axe/mini, Lurker's is the only one that actually changes how the bolt operates. It comes with an aluminum spacer that slides over the bolt guide, replacing the stock bumper oring. The rear spacer allows the bolt sail (the back face of the bolt that air pressure acts on) to be much smaller then stock/other bolts. This decreases the initial force of the bolt movement, making it crazy gentle on paint. How gentle? I can shoot evil paint at 290fps then take a single ball in the breech and hold it slightly out of the chamber to simulate a chopping situation. The bolt lightly taps the ball and bounces back. Same if you stick your finger in the breech and pull the trigger, it just bounces off your finger. The definition of how "gentle" on paint a gun is how much force the bolt exerts on the ball in the breech. So that makes Lurker's bolt one of the gentlest on paint ever, for any gun.

I'm not sure if you are familiar with how the axe's bolt operates, but the reason the stock/all other bolts have two outside orings is so the last one cuts off half the solenoid flow at the beginning and ending of the bolt's cycle. This design makes the bolt gentler on paint, but it unnecessarily slows the bolt on the return stroke. Lurker's bolt only has one outer oring, so no flow is cut off from the solenoid. This speeds the bolts cycling up, not wasting any flow. It's really an ingenious design.

I'm using techt's stiffest spring with my eigenbolt atm. Here are my settings:
140psi
3.5ms dwell
1.5 turns out back cap.
chrono 290 +/- 4

I have zero kick compared to stock (well not zero because there is always a bit of recoil due to the ball being fired, but it's ridiculously smooth. I also get around 11-12 pods from a 4000psi fill.

I would highly recommend Lurker's bolt, best upgrade I could suggest for sure

Here's a vid of Lurker's bolt doing a ball pinch:

My gf saw me doing a pinch test and said she wanted to try. She was like "that didn't hurt at all!" lol

Remarkably well written and argumented. Thank's for your input and the explanation regarding how the bolt works as I was not aware of this. So far I am leaning towards the lurker bolt based on your explanation. Thanks for the vid btw, any chance you could post one putting a couple shots through with the lurker bolt or comparing it to stock/techt? Does anyone have a different (well argumented) opinion?

Yeah that pinch video wasn't mine, but illustrates how gentle the bolt is, I can attest to it being accurate I will be making a vid in the next couple weeks that has a few different things in it. Just to stop people from being like "oh well it's pinching paint because he probably has his settings turned down for it that's why he doesn't shoot it first". I'm gunna make ONE vid that shows a 5 shot chrono reading, followed by me shooting at 12.5 psp, followed by taking the hopper off and doing a ball/finger pinch test. Here's a link to the eigenbolt thread, if you scroll down the page in the link you'll come to a picture installation guide, it'll let you see how the bolt works a bit better.

Fantastic illustrations for the lurker bolt

The thread is starting to seem a little biased. Anyone care to put in their 2 cents on any of the other bolts? For the benefit of the community ofc.

Yeah that's crazy, almost the same settings I have. Makes sense since he's using the same spring and bolt as me, lol. I just upped my dwell a bit higher than his so I could drop my pressure to 140psi.

You get the idea though.

Unfortunately, you're probably not going to find anybody who has tried more than one or two bolts, seeing that each one is around a $30 investment. I wish I had that much money to throw around, not only for my own benefit, but the benefit for everyone on PbN.

I chose the Lurker bolt, should have it before the weekend.

The poll is showing the boss bolt over the lurker 7/5. Anyone care to share their point of view on the boss bolt?

I'm sort of in the same boat here, getting an Axe and I'd like to see which bolt everyone is most happy with. Looks like it's a two way race though so I won't go with the Tech T bolt. Where do you get the aftermarket spring kits from though?

I'm curious as to this too, surely 15 people had a good reason to vote for it other than the fact that it happens to be what they own

the lurker and ndz bolts seem to be lacking the soft face.

btw what is the weight of the stock bolt? The stock bolt seems pretty good, do these aftermarket bolts have the same soft face as the stock bolt?

The lurker bolt not only has the stock soft face, it improves it by giving an air gap for the rubber to fold back into. Feel on the tip of your stock bolt. Try to compress where the ball would sit back into the bolt. You can't. The stock geometry there allows for very little compression and is almost as bad as aluminum. It's a fist wrapped in a tight rubber glove.

The lurker eigenbolt, on the other hand, lets the center diameter of the insert move backwards into a chamfered out air gap. Think of a pillow in other guns - it's the AIR in the rubber foam, not the rubber itself, that is creating a soft-touch effect.

I assume no other aftermarket bolts have this, because if they did, they'd advertise it. I really tried to stay out of this thread, but I just can't do it.

I actually made one like that during prototype testing. I felt going the way I did would be better over long term use. Especially since we have no issue breaking paint with either version.

And yes I have desided to stay out of this thread. Both seem to be quality products and the entire community wins.
