The Mercury bolt for the Impulse is one of the lightest Impulse bolts in exsistance. The front end of the bolt cups over 1/3 of the ball, improving efficiency. Test have shown that replacing any other aftermarket bolt with the FBM mercury allows you to lower the dwell of your gun, and still retain the desired velocity.
The Fireball Mountain Mercury Bolt is older, so while it may be available used and in a few cases new, it is not commonly available anymore.

The one thing that sets this bolt apart from all the others: PRICE. This bolt is definitely better than the Shockteck Superfly and MUCH cheaper. There are so many delrin bolts available and if you pick a well known manufacturer you'll have a hard time finding a bad bolt - so why spend more?
19 bucks well spent.
If you need to buy a new Impulse bolt, this is it. Even if competitors are as good, they're costlier.

Really light, white delrin for was board, speed (raised my bps by 6) self lubricating

A great bolt for its price... i got mine for 21 dollars. My TonTon came with a long bolt and it just couldnt keep up with my internals and my super fast trigger fingers. I decided that it must be the bolt. I went looking for the superfly bolt a PBReview.com. I noticed that several were saying that the fireball mountain bolt was really good. So i decided to try it out. WOW!! That thing is hot. Like i said this bolt should raise your bps by about 6!! Pair this bolt up with the fireball mountain delrin trigger to raise it 10+ (i got 14)
I say go out and buy this product, and the trigger too, you will be glad you did.

Lowered my dwell 9ms, Very light, reduced kick.
I would recommend this bolt for anyone. The bolt is alot lighter than the stock bolt, and you don't have to lube it. It made a large change in efficiency, and my accuracy increased. FBM makes very good products and I would highly recommend their clamping low rise as well.
Great product, if you still have a stock bolt go out and buy this. If you have an autococker they make bolts for them too.
