A bit short, nothing to grab on the back to pull it out. Large diameter.
I bought my BKO used, and after testing for blowback, i found that i had EXTREMELY bad blowback. Got the Vapor bolt for 20. Went to put it in my gun and found that it was a little bit hard to get in, so i lubed it up with white lithium grease and slid it forward and back a few dozen times. This seems to have solved the blowback problem.
A must if you have blowback. If not, why get a new bolt?
04 BKO w/ Macdev red valve & feed tube, Dead On drop, 12" CP barrel, Vapor bolt
O-rings stops blowback.
Manufactuing quality, o-ring drag.
Nice bolt , approximately 1/2" shorter at end than stock. Grey color goes better with gun than stock bolt. Does seem to generate some dragdue to o-rings. If front o-ring is oiled/lubed the residue left in the breech area decreases acuracy compared to stock. The manufacturing quality is poor, all milled edges were sharp and had to be smoothed down prior to use, inner & outer face edges, o-ring groove edges.
Does what it is supposed to do, stop blowback. If a better alternate is available I would get it over the Vapor and I may still if I find one.

We did not detect any blowback at all. Smooth operation. No chops(although this could be the effect due to the other VAPOR mods) Low cost effective upgrade = more bang for your buck.
The bolt will drag a little more than a stock bolt, but I don't think this has any negative effect at all. It is shorter so it takes all of 2 more seconds to remove than the longer stock bolt.
We gave it a 9 only due to the fact that we have not had it very long and have as yet to fully realized the positive effects of the Vapor bolt. If you are going to upgrade bolts, this should be your first choice. If you have blowback problems, this should almost always fix it. Besides, the Vaporworks has treated us very well.
Bolt drags, too short, ball seat and spring inside bolt were faulty, poorly manufactured.
The bolt makes for worse effiency.It drags creating more force needed to push the bolt.
The spring inside the bolt was poking out and bent.I had to replace before i could even test it out.You have to lube the orings.And most of all it is a hassle to get.
Save your money, make your own.Not worth the time or cash.Junk.
This bolt is designed to reduce the blowback that some markers get with the stock bolt. The delrin doesn't seal in the breech well. The orings take care of that. You can put a business card over the feed tube and hold your hand over the barrel as you fire and it won't even bobble the card.
Less blowback means more air is hitting your ball making it a little more effiecient and getting a better velocity.
A new nylatron model is being released that is much stronger and "slicker" than the previous versions.
Not perfect for all guns. Some bushys have a smaller bore that won't fit the vapor bolt properly.
It needs to be lubed, adding another maintenance step, but nothing major.
It's a good upgrade for the price. Other bolts claim to be better, more efficient, etc, but the vapor bolt does what they claim at a very good price. I'd recommend it to everyone. Vapor products rock!

It only cost $20. It gets rid of blow back. Also, it gets a higher Feet Per Second at the same pressure. It is lighter. It is more accurate and gets more range. I chop less paint.
It is a little short, but it only takes a second longer to take it out. The ball detent wears away the bolt, but not much.
The bolt is a must. You get a lot for a little money. It improves the bushmaster. Gives it more range and makes it more accurate. The bolt being short it not a problem. It gets rid of blow back. I chop less paint. Buy it!
This was on a 1st gen B2K , vapor valve , fmd mod and cp .693 2-piece barrel.
The Bolt eliminates all the blow back problems the tested maker had.
The operating pressure was lowered too.
The Vapor Bolt is made out of some kind of plastic instead of derlin like the stock.
The Vapor bolt was flawed but Goldie has taken care of that for me.
The Vapor bolt is to short, it makes it hard to remove from breach.
The o-rings on the Vapor Bolt cause slight sticking in the breach which adds to the difficulty of removing the bolt from the breach.
The Vapor Bolt does its job by eliminating the blow back but you must sacrifice some convenience with it.
The Idea is great, maybe the next version of this design will solve the length problem and control the quality better.
