Solved BlowBack Problems
I got this bolt used from somebody online, and as soon as i poped the sucker in it solved my blowback i had no kick anymore! This bolt is awesome for anyone who has blowback or who is looking for a great bolt for a modification for there BKO or other bushy.
My inital thought on this bolt was the same as many i've read, Bolt was too short! however i get nice and close to my gun when i shoot, so the shorter bolt is nice, since it doesnt come out the back of the gun you wont crack your mask when it loads the next ball. I had one bolt actually break, called sam and explained the situation, i recieved a new bolt in a week at no cost. I've been using that bolt for the last 1.5 years without a problem.
Anything Vapor is a good idea, He doesnt charge alot and his products and back with great service, and are good quality. Always nice to see someone stand behind their work and take pride in it!!!
this bolt is a lot better then the stock bolt because of the o rings. they do seem a little loose though and i have gone through the 3 extras that they sent with it. but they are cheap to replace and it helps with blow back issues if you are having any.
in conclusion i think its a pretty good bolt. some people say it is too short but it still sticks out a little so you can get a hold of it. if you are having probs with blowback get it, or if you have access to a lathe and you're fairly bold you can make your own with the stock bolt. anyways, im giving it a 9.

stops blowback, nice color, little bit air efficient
machining not perfect and i dont know to use to loosen the bolt pin thing
i put the bolt in my gun and it went in extremely well, perfect size.I went to my back yard and put a credit card on the feed neck and shot a lot of times, and the card barely moved,so it worked.ummm i love this bolt! it solved my problems! ahhits great and i love it now. gives my gun a better sound i think
i think its really good if u have blowback problems or stuff like that and blah blah blah its really good go buy one today. oh and its shorter than stock,so that when u shoot it it wont pop out of the back of ur gun

stops blow back
helps air efficiency a little
if you have blow back get this bolt it will get rid of it.also the bolt fits good in the gun because off the o rings on it. also i think that it is nice that this bolt is not delron so that way you don't have to worry about it swelling.
if you have blow back on your bushmaster get this bolt you will be very happy
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?

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.

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.

too much friction
Here's the story I bought my b2k used on ebay with a few things done to it. Right away I ordered the vapor to go kit. I installed it, and I have only used the maker once before I installed the vapor parts. I thought that my marker was too loud, so I sent it to be vaporized hoping that it could be tuned to be quieter. I got the marker back with the cool vapor jewel and new hid blue light, but when I went to the field it was still loud, the bolt was greased heavily when I recieved my marker and I broke a ball that day and had to clean my bolt therefore wipping of the grease, I forgot to get my grease so I decided to slap in the stock bolt. I shot it a few times and the paint was winging. I brought it to the chrono and it was shooting 340fps wow!!! So I was able to turn the pressure way way down and was shooting 290fps @ 170psi. The marker is now literaly ten times quieter, more consistant, and I have broke zero balls. My conclusion is that the bolt is good for some bushys but my body is too small for it to work properly, will I ever get rid of blowback and still have a quiet marker? I don't think that the product is bad it is just my marker, it isn't for every bushy.
buy it and try it if it doesn't work for you oh well sell it to a friend and try a new bolt.
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!
