Sure, I'd say thats a fair assesment. But where do you draw the line between money spent, and marginal improvement? When I say works fairly well, I mean I dont want/need any more outta my marker. I'm happy with its performance. But none the less Shartley, your comparison is a good point.

Sort of like spending $300+ to save say ~3oz on the total weight of your valve ...

The point of the system is to decrease, blowback to 0, and to increase efficiency.

Actually, I could have used something like that, but for a reason other than blowback. I'm usually forced to shoot small caliber paint, and so usually used a smaller insert. This caused problems for my bushy, because the front of the bolt was actually bigger than the insert, which meant it couldn't come forward all the way and hit my valve stem. Although I doubt that's what the maker is getting at, I don't think it's totally useless.

Iv known (not personally) Josh for a few years. He seems to know his stuff. This particular product is VERY helpful in some instances to prevent blowback up the feedtube (as well as help boost effiency). I have a Spanky Cobra cocker body with the upper tube so large that the blowback would leak past the bolt tip on firing and litterly toss the next balls in the stack (no hopper) about 6' up in the air. I ended up making my own oversized bolt tip which fixed it beautifully... but this was before he came out with the Deviant so I had no alternative.

out!

I would hope that makers of paintball markers would hold to a higher tolarance level if this was such a high problem area. I also would assume that if out of spec the body would be melted down. just my guess what some places do

Well looking at this from the outside of the box I think it is a great idea and mainly for one reason. You have small bore paint(Or I should say variable sized paint), you can now match the bolt up with the paint to limit the amount of "smack" on the next ball in the the stack which is the leading cause of most barrel breaks in most guns. The speed and force of the bolt can put a small crack on the next ball depending on how much of it is hitting the top edge of the bolt. Blowback.....with loaders like the Warp feed and Halo, you do not have to worry about balls back up the feed stack. I can't speculate how many shots you will lose per tank fill because of more blowback, but I would want to think it would definately save some barrel breaks. I thought of this before lvl 10 and using a setup that used different sized bore's to try to eliminate the problem of "ball bobble"(top edge of bolt hitting the bottom of next ball waiting to chamber). Same idea with using the different sized tips.

I will gladly wade in here and take on the naysayers-

My name is Josh Coray, I came up with the concept for the Deviant (formerly the Mutant) Bolt System. The design is mine.

The bolt was designed to solve MY problems with setting up Race Cockers. If you do not have blowback issues, then I didn't make it for you.

One of the biggest problems I had was blowback from small Outside Diameter Bolts like the Superfly. The superfly is suppose to be a 'Tolerance Fit' bolt that has a delrin portion that seals in the breech. The problem is, the superfly has on OD of .679-.680. With a common breech sized between .688-.692 on a cocker (due to manufacturer, anno choices and number of times annodized) there is going to be blowback due to the difference between the bolt and ID of the breech being far to large.

After hunting, I found custom handmade bolts that would fit, but I would have to have about 5 different OD of bolts, times 5 for different lenghts (pre-2k, 2k, P-blocks, etc.) I would have had to have 25 different bolts made to take in any one gun that would walk through my door.

Or I could have tips made that would fit on the different backs. So the tips could fit the gun I had in the shops breech, and then I could grab the back that would match.

Then I realized I could throw 3-4 tips in a package with a back and sell it as a kit.

So, this was originally a real world problem solver for myself. Not a gimmick whipped up by some nobody. Over 12 years in the sport, and I hate gimmicks.

Does you bolt seal well? DO you know the difference?

I had a gun that would cycle 15bps, a really nice cocker. Open time with a HALO would be about 10ms. I couldn't put the load below 45ms. With a HALO. Or a WARP. Because of blowback. And another gun I had in the shop at the same time had the same problem, even with a load time of 55. After I found a good sealing bolt (one with 3 o-rings) the guns load was turned down to 10 again.

The difference in speed was 15bps compared to 8-9bps, with a HALO. Can you imagine having a HALO and not being able to shoot over 8bps?

Including critisism-

aja ended up buying the rights and releasing as the Deviant because he liked it so much, here is what he said:

that mutant bolt thingy

I got one of the first run of them, I figured what the hell, I've tried every other bolt out there, what's another $50, right? There have been a few different bolts with multiple heads, dating back to the old cooper-T days, most for different venturi patterns. This is the first one in the 13 years I've been playing/working in the industry that I've seen that matches breach size.
I got the box in the mail, opened it, and my first reaction was "that's freakin ugly!" After looking at it for a while, shooting a couple cases with it, dropping the pressure on my cocker 100psi with it, eliminating blowback almost entirely with it, I still say it's freakin ugly.
I do have to give him credit on this one... Good work! I like the idea of a completely oringless delrin bolt. They're fast as hell, no orings to wory about keeping lubricated, but they've always been a bear where blowback is concerned. I've had a couple delrin's that were so bad the feeder looked much like a popcorn popper (shocktech comes to mind). I know the gun is timed correctly for the vaccum effect, it works that way with an aluminum bolt. I always end up back using the stock WGP bolt. It's a little sluggish, but the open face seems to work best for me. I found it's replacement!
It's faster than anything else I've used, requires a lot less pressure going into the ram to move the thing, the input pressure can be dropped a bit to compensate for the larger openings and less resistances, overall, the thing gets a B+ (it would get an A if it wasn't so freakin ugly!)
It's pretty rare that I write a review on a product. There just aren't many I like enough to say "yah, I'd admit I use that. Hell, I like it so much I'd stock it at my store" Well, it's on the shelves...

I really say this is one bolt people should try. No, it's not venturi (thank god). No, it's not the prettiest thing, but it's in the gun 99% of the time, so who cares (except me of course). For the price of this bolt, you could buy a bolt that you'll use twice, realize it sucks and toss in your toolbox, or find some poor kid on ebay to buy the PoS, or you can pick up a bolt you'll actually use. (and you'll buy it from me of course!)

Okay, if you have read this far, please reply.
