The latest generation of the HollowPoint bolt is ready! The
new silver-colored HP U3 bolt adds a paint-friendly rubber nose, which
is gentle on even the most brittle of paints. This means the HP U3 can
be used in any Ion/Vibe/XE/SP1 setup - with or without QEV - including
those using the Blackheart board in their SP1's.
The HollowPoint Ion bolt is the original of it's design, and
the U3 is the result of years of development. The HP U3 Ion bolt uses
Hollow
Valving™technology which eliminates the use of multiple ports
through the bolt --the bolt is one big hollow port! Multiple ports in a
bolt introduce structural weak points and air flow turbulence. Hollow
Valving allows the bolt to be much lighter, stronger, and
higher-flowing. The HP U3 Ion bolt also incorporates our
ARB™
(Anti Roll Back) technology. ARB™ eliminates the "ball roll back"
problem typically caused by any open or deep-type bolt faces.
Installation
instructions here.
- 9.0 gram bolt. You won't even know its cycling. (The blue "stalk"
does not move)
- Lowest kick.
- Over twice the valve area and flow path as a stock Ion bolt.
Opens faster, flows better.
- Contiguous toroidal air flow path. No porting to break up
the air flow into efficiency-robbing turbulence.
- Longer bolt nose section takes better advantage of the Ion's
SFT seal than the stock bolt.
-
ARB feature prevents
ballstack chops caused from the ball rolling back into the cupped bolt
face.
- Controlled condition testing yielded 1800 full 290fps shots @
150 psi from a 68/45 tank. Expect to get 1500-1600 in typical use.
- Quick, easy install.
- NEW U3 version now uses a universal
stalk that will work in both the "original" Ion AND the XE versions. We
include the mounting hardware for both!
Works with:
- Original generation Ion, Lucky 5.1 bodies
- Ion XE, Vibe, SP1
*At this time we do not suggest using the HP bolt in the
Epiphany or EOS due to the higher required operating pressure.
