We have designed a newer, lighter HP bolt! 6.3 grams and two-stage ID for for even less friction without risking leaks.
The HollowPoint Ion bolt is the original of it's design. Over a year in development, the HP 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 Ion bolt also introduces ARB™ (Anti Roll Back). ARB™ eliminates the "ball roll back" problem typically caused by a deep-cupped bolt face.
Installation instructions here.
6.3 grams takes the cake again for the lightest bolt.... ever!
- 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.
*We do not recommend using a QEV with this bolt. It simply moves TOO fast and can cause paint to break. Side benefit: save yourself some $$ and complexity.
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.
