Comments

The IPB Delrin bolt was the first and for a long time only upgrade bolt available for the Impulse.  The whole purpose of an after market bolt is to add performance.  The IPB Delrin bolt does that and then some.  First, it's Delrin.   Everyone loves a Delrin bolt...why, because they don't have o-rings and do not require lubrication.  That equals less overall maintenance.  Second, Delrin weighs less than aluminum, so with less weight to move, your Impulse will require less air to cycle and therefore become more efficient.  Third is actually second part two, again because the bolt weighs less, it will cycle easier and reduce if not eliminate the little kick that the Impulse has to begin with.  This assists you with accuracy.   With your Impulse kicking around less from shot to shot you will be able to maintain you aim better, therefore increasing accuracy.

The Details

  • SIZE: The IPB Delrin bolt is the same length as the stock Impulse bolt, 5 11/16 inches long and uses the stock bolt pin.
  • STYLE: It is a venturi style design with one hole on top and two holes on the bottom.  Interestingly enough, this is the opposite of the stock aluminum bolt which has two holes on top and one on the bottom.
  • COLOR: This is all about the COOLNESS FACTOR!!  Nothing is more cool than having your Delrin bolt colored to match your Impulse.
  • MSRP: Price is $38 for white, $41 for solid color, & $44 for fade.   Limited Edition available in Earth, Water and Fire, price $49.
