All the goodness of the Undertow, now available for your Spyder. (See Impulse Undertow bolt for Undertow description) Tapped to accept you stock rear cocking rod,if needed. Also available in rear cocking/Shutter style bolt. Completely delrin, 1/2 the weight of the stock bolt. Requires NO lubrication. Complete with groove for ball detent. Lighter, faster, & Undertow technology.
The Imperial Paintball Undertow Bolt is older, so while it may be available used and in a few cases new, it is not commonly available anymore.
This bolt raised my accuracy by at least 30%. I have a "Range" set up in my back yard, from 38 feet away I was putting 6 of 10 balls in an 8" shot pattern before this bolt. and now I am putting 9 of 10 into the same 8" shot pattern. Honestly running CO2 in a starter gun, you cant get much better. Aside from that dealing with the "WERM" the guy that acctually machines these bolts from scratch was great the guy has excellent customer service.
Go to the website for a complete and accurate breakdown of the bolt and the undertow tech it is based on.
This bolt is outstanding, For the retail of around $40, you cant beat the quality.
I ordered one from Imperial Paintball (WERM) a month ago and I haven't seen or heard from them (him). Emails bounce back and the toll-free phone is disconnected. So, I bought one on Ebay for a lot less and got it within two weeks. If WERM pulls through and it does come, I'll be getting rid of one so if you are interested let me know.
As for the bolt itself, it shoots straighter then stock (10" groups down to 6") and it shoots a hair further. I have only put about one hopper through it and it double fed three times. I haven't looked yet to see if it pulls back that much further, but it could be due to my also new Evo2.
I give it a 9 for performance and 1 for service. Like it or not, part of a product is the sales process.
It's cheaper than a really good barrel as it allows you to use a variety of paint in a more forgiving barrel (straight bore) and still have decent accuracy. I'd say get it, but only if you don't have to deal with Imperial Paintball. (I understand making things to order, but no communication at all? That's bad business.)
stock everything else
much more accurate, a bit more distance, cheap
shipping takes forever
made my spyder sonix have great accuracy, very consistant with every shot, i got a little bit more distance (but its nothin to brag about) the total price including shipping was 35 bucks. this is a great bolt and anyone that is thinking about buying this should because it is a cheap boost for anyones gun.
great investment in money, really you wont be sorry at all for buying this, the only problem is shipping which took one month exactly ,but im here to rate the bolt not the servive I got so this gets 10 out of 10
Java vert feed
Very accurate, increases distance, no crappy o-rings, looks great!!!
Not what i expected but still very good, bad service from ipb
When I got the bolt from IPB, i had waited 4 weeks, it looked great! I ad no problems installing it what so ever. I shot my gun and boom that ball went alot farther than the crappy stock vetri. I have alot better long range accuracy and distance. I highly recomend this bolt
Great bolt, looks even better i give it a 10 and i recomend it to anyone
Spyder Xtra, 14in. Nite Stick, 14in. ACI Zero Gravity, 8 in. drop forward, 8 cell expansion chamber, Undertow bolt, ESP trigger, Regulator, Evollution 2
they take forever to ship, 2 months for mine,
this is a pretty good over all bolt, the undertow technology seems to help some. I had to grind down the pin that connects it to the striker because it came to long and you can't adjust it. you can't get a hold of the company if you want to.
good over all bolt, the delirion bolt is helpful for field stripping (dosn't need oil), I would recomend this bolt to anyone who dosn't mind waiting 2 months to get it.
7 out of 10
