CNC machined bolt made from Nylatron.
Self lubricating material.
Maintenance free (no '0' rings to oil).
Smoother action (no scuffing in the chamber).
Lighter in weight than stock bolt.
Open face giving maximum airflow.
Better fit in chamber creating more air efficiency.
Reduced ball breakage.
The cheapest effective upgrade for you marker.
The APM Products Tigershark Bolt is older, so while it may be available used and in a few cases new, it is not commonly available anymore.
The stock bolt... it wasn't that bad, but not that great either.
If you REALLY wanna see my setups... which I doubt, go to:
- Cheap (price)
- Perfect fit
- Very light weight
- No O-rings/oil needed
- Secksy looking!
- Ehhh...shipping? (It took a while, but then again APM is in Canada...)
When Flamin'Skull first posted on the Kingman forums about a new bolt he was developing, I was skeptical. However, since he took input directly from us in the design of the bolt, I decided to plunk down the $11 he wanted for it. Boy, am I glad I did!
First off, the customer service was great. Flamin'Skull helped me to place my money order (I had no credit card...), and promptly informed me as soon as he received it. The package the bolt arrived in was very well protected, with the bolt having no damage upon delivery. When I first installed the Tigershark into my Avant, I immediately noticed something: All the side-slack and rattling I was used to from my stock bolt was gone! In short, the bolt fit perfectly into the chamber. I was already impressed, and I hadn't even gassed up my marker yet!
When I dry-fired my marker a few times (to make sure that the new bolt worked), yet another amazing realization struck me. As I was looking at the feed-neck, I noticed that there was not the usual "puff" of CO2 that was oh-so-often released when I would shoot. Just to check, I stuck the back of my hand over the feed-neck, and felt absolutely no air at all when I would shoot. The perfect fit of the Tigershark in my chamber also had the strange little side-effect of drastically reducing my blow-back. Also, as I would shoot my Avant, I noticed that the kick-back was slightly reduced, due to the fact that the Tigershark weighs much less than the stock bolt.
One of the key strengths (besides the perfect fit and all that) of this bolt is the fact that it is made out of nylatron, which, like delrin, is self-lubricating. Unlike delrin, however, nylatron is less prone to swelling. Also, the milling of the bolt as well as the cool "swirling" pattern was a nice feature.
As of yet, I have not tested the bolt with paint. When I do, I'll edit my review and let everyone know how it goes. |8^)
Well, I finally got to put some paint through my marker with the new bolt installed. As I predicted, blow-back is now a thing of the past. Just to prove it (to myself, mostly), I stuck two paintballs into my feed-neck, and fired off one shot. With the stock bolt, doing this would make the second ball in the feed-neck fly a few feet into the air, but with the Tigershark, the ball didn't even leave the feed-neck! Needless to say, I was most impressed. My second test was to chrono my marker, and see if there was any velocity increase. Upon testing, I noticed a 3-4 FPS increase on average, which, even though that isn't that great, my venturi on the stock bolt I was testing was already removed. Some time ago, when I removed the venturi, I recorded a 9 FPS velocity increase. So, to be fair, this bolt would (on average) give the user a 12-14 FPS velocity increase. Also, while testing, I noticed that the marker was slightly quieter and had a less "metallic" sound to it, due to it's nylatron construction and perfect chamber fit.
Well, this bolt swelled up on me. It wasn't anything catastrophic, but I did have to sand it down.
NOTE: APM HAS BEEN INFORMED OF THE SWELLING PROBLEM AND HAS FIXED IT!
In conclusion, I still stand by my recommendation that you order this bolt immediately!
Most people say that a new bolt will not make that much of a difference. Normally, I would agree, but this bolt is different. Buy it.
For $11 ($15 now...), you can't lose.
However, if you have more money to spend, I would reccomend the ACP Blue Bolt over it, or the White Wolf, since APM seems to have gone out of business.

Spyder E-99 avant, Tiger Shark Nylatron bolt, dead on drop, 14" 32* Terminator.. thats about it..
Price!!! very light, looks cool, reduces blow back overstock bolt
May break easy? Like if u smashed it with a rock.. bolt swell
I got this bolt directly from the manufacturer.. Cheep bolt.. i got in on the 11$ ones but at 15$ its still a deal... placed this in my E99 and there was very little play which i like.. started firing and shooting seems about the same but there is less kick.. gun is also much quieter.. when i have a chance to get on a chrono i will update about speeds..
UPDATE** i wanted to update this after game play.. played and this bolt rocks.. no chops at all (i got a few chops before).. also a some friends of mine have the bolts for their guns and there was only one chop between the three of us.. as far as the speeds, didnt see a diffrence..
UPDATE again** this bolt was taken out of the gun while i atempted to get money to play again.. the bolt swelled up and will not fit in my frame anymore.. it was inside and other than power outages from the hurricans it has been at room temp.. still a great product.. if i had another one i would be in my marker now.. just fyi
Great product!! cheep even at 15$ would totally recomend.. awesome cheep upgrade!

Once i saw the package i was like WHOA.. i took it out of the package and was amazed about how light it was..( pretty light) i was comparing it to my stock bolt and it was alot more snug too.. i dont have my reg yet so it was undecided about how low i could get it. but i went through a bag of crummy TORK balls.. and didnt break one.. this is an amazing product and i LOVE it..
Get it.. its probably the cheapest GOOD aftermarket bolt on the market..
Just got back from the field, an to let you all know that this is a great product. I could not get the aka.. bolt to recock below 350psi, I tried with few different springs.. an its kept burping... when I tried.. to Bring.. to pressure.. down..
So I get TIGERBOLT in, it preformed great I got my gun dialed in with the tigerbolt @ 300Psi @ 280fps... I did not chop any paint, its seems IMO that it made my gun a lil quieter it worked flawlessly on the field, so yah I HIGHLY Reccomend this BOLT to anyone. good luck on you business I will recommend this bolt to all my frens
