Made of frictionless delrin, this bolt uses space age wind force cyclonic effects to create an upward spin on the ball, to propel the ball further than gravity would allow. It also comes standard with the signature series E jewel attached to the rear of the bolt (obviously the key selling point). It also has a cool little twisty design to decrease surface friction or something.
The Evil Rear-Cocking Delrin Venturi Bolt is older, so while it may be available used and in a few cases new, it is not commonly available anymore.
This bolt is awsome. I hesitated to buy it at first since I knew it wasn't a flush-cocking bolt, but there is one way to make it flush. After receiving an e-mail back from evil I found out that if you take the plastic guide o-ring off of the flush-cocking rod you can make it work instead of using the evil cocking rod. And to boot you can take the evil jewel off the evil cocking rod and stick it on the stock flush-cocking rod, it fits perfect!
For approx. $35 it is a inexpensive and great upgrade for any piranha.

More accurate than stock
The Evil Jewel on the back
I wanted a delrin bolt because my stock was scratching up the inside of my gun. i got it and put it on and went out side and shot small pole from 100+ feet away the first shoot accuracy was sweet if i can see something and hit it right on the dot . My groups are better than stock but thats probably because of the cheap paint iam using. it a venturi so that probably is the reason for the accuracy. The Evil jewel on the back of the cocking rod is cool to
It a lot better than stock it looks good get it if you want improwed accuracy and delrin bolt i dont see why not

when its lubed it works so well
This bolt was well worth the money i paid for it. I got my for $20 because i know the owner of the store but this thing works great its quiet fast and accurate all my freinds like it and it hasnt chopped paint once. I love this upgrade and it was the first evil product i ever bought and now i know that i will be buying more of it. so in the long run this is a great bolt for the money.
Buy this product if you can because it is well worth the money. :@

Decreases wear on gun
Breaks less balls
Increased cloud size from the end of the barrel (C02)
A very good product, definetly the most worthwhile upgrade to your Piranha, second only to a new barrel. The increase C02 cloud is noticably bigger on my setup, especially on hot days. With the bolt installed my marker lost the metal 'ching' sound when it fired, making a pretty quiet gun much quieter. I also find with the bolt I can use cheap paint (Rec Sport) without fear of breaking a ball like I did with the stock bolt.
I bought this accessory halfway through the 4th year that I owned my marker, and it has made a huge difference. After being able to use it for a few games last year and one so far this year (stopped for winter, no indoor places around here) I can say that this product, though expensive, is a worthy addition to your gun.
piranha srt with black green grey fade paint. the new eforce trigger the ventri bolt a 12 1/2 inch progresive barrel evil feed and thats all i need to make this gun awsome
Fast Quiet Dont Chop Balss Never
With Co2 It Leaves A Small Cloud Thats It
I think the piranha is a good gun for the money with my upgrades its almost perfect. Got to get over fifty words so here it goes. Some body once told me the word was gonna roll me I aint the shapest tool in the shape. I 'm a barby girl in a barbie wolr its fantastic made of plastic. Devil went down to gorgia lookin for a soul to steal . I fell in to a burning ring of fire i went down dow n dwn bu the flames went higher and it burns urns burns the ring of fire. Buy the piranha
Buy this gun and upgrades beginner or not its a great gun and will support you if you support it.

Overall this bolt is better than the stock bolt......... It is way better because it lubricates itself... This bolt is very very quiet when you shoot it. This bolt may even increase you rate of fire a bit, maybe 2-3 balls per second, with is fairly good... I can get about 13-14 balls per second if the Extreme Rage Overdrive Hopper is in its highest setting....
I think this upgrade for your PMI Piranha is very good...... Also you should consider getting this bolt and a new barrel.
Piranha E-Force VTL, 14in 32 degrees Ice Cold Barrel, 4 stage ACI Sub Zero Expansion Chamber, Evil Delrin Bolt, Halo B, Empire Reloader,Dark Horizon Titanium Hammer, Palmer Male Stabilizer, PMI/Pure Energy HPA 48/3000, 14in Dye Ultralight
Maybe a few more O-rings
This is a great upgrade for any marker. Really any Delrin bolt will be a improvement over the stock metal ones. Its weight really keeps the kick of the marker down and as for improvement in performance...the chops have definitly droped. I just recently modified it by using a dremmel, time, and patience, by cutting/sanding out the venturi holes in it. They were just made of the delrin so using drill bits and sanders on the dremmel i just shoved them up the shaft of the bolt (carefully) and cut out the venturi and made it smooth inside. I did this because if you think about it, the air (co2 or HPA) is used to propel the ball right...well the location of the venturi part on the evil delrin bolt is right at the beginning of where the air will hit the bolt...so my thinking was....if that air has to pretty much hit a "wall" and then push itself through holes (venturi) wouldn't that slow down the air...I haven't got to use my gun yet this year but it isn't like the evil delrin bolt is now destroyed and won't work...it is just hollowed out, lighter, and i believe going to improve my velocity. Also with the comment of the few more orings above in key weaknesses....its not a big deal but I think if they placed a o-ring on both sides of where the air travels into the bolt and through it...i think that would "seal" the chamber better and increase flow...This is available on a lot of metal bolts and some other delrin bolts...It isn't a big deal that it isn't available on the evil delrin bolt...but it might help something.
Nice upgrade, like I said before...the mod i did on it may not help any but it also can't hurt just taking in the idea that the air has to push through holes...worth the money and investment in not just this bolt, but any delrin bolt out on the market.

On my piranha I use my 48/3000 pure energy and a 12 v revvie
Never breaks balls
The stock bolt on my piranha chopped like there was no tommorrow. I got this bolt for 35 and didn't break a ball until I had shot through 2 cases of paint, and the ball that chopped was PMI Big Ball(Seconds). This bolt is awsome. It is super light and it seemed to make it shoot a lot more accurate, even from a 9 inch stock barrel.
Get this bolt if you don't want to spend half the day cleaning your gun out. It makes the day a lot more fun.
