I have ordered my threshold and it's coming sometime in the next week as my distributor is only just receiving them. Are there truly different versions of the bolt's design floating around? What are the primary performance differences between these different setups (if in fact there are differences)?
Given my threshold is just coming in, what design would you expect mine to come with if in fact there are different versions?
Anyhow would someone please clarify this? (sorry if this is a common question but I haven't been able to track any thread down about it)
my guess is that dp has tweaked the design a bit differently to get around patents..
for example every marker needs an effective way to seal the breach during firing, some people put an o-ring(or two *patented by eclipse) on the very tip of the bolt, others (smart parts) choose to put that o-ring inside the breach which they consider their seal forward technology. my guess is that the original design had an o-ring inside the breech because it makes it easier to pull the bolt out of the back because of the design. But smart parts would ***** so they probably decided to put it on the bolt time..
Now the rear o-ring is was seals the air source during the firing process. That is a direct violation of dye's patent, so they shipped the bolt without that o-ring in place (however I still believe that can be argued at contributing to a patent violation).. now my guess is that they probably originally put that o-ring inside the bolt tube so that they can claim a very minimal amount of o-rings on thier bolt.. this would cause an issue with the ease of putting an o-ring on (and probably add some extra time to the assembly process). so they just threw it on the bolt..
The bumper is a relatively new ground in paintball. everyone realized that the bumper softens the cycling process or atleast makes the end user think it reduces kick, so it's safe to assume that they didn't include it in thier proto-types or early bolts because 1.) they might have wanted to thoroughly research whether it's been patented 2.) it slightly reduces the time needed to produce the bolt, and if it was a beta version then it wouldn't matter anyway.
My guess is the most current bolt would have the bumper and the bolt tip o-ring, and a slot at the rear of the bolt not containing an o-ring...
wow, I'm pretty long winded today..
