Through initial testing, benefits we have seen...

1. Have a tighter chronograph grouping.

2. Add 10 to 15 ft per second over the chrono. 

This should allow you to lower the pressure of your marker while achieving the same velocity. This is great for mechanical use when there are no eyes to allow for more brittle paint.

We made them brown so people could continue to complain about our brown bolts. 

*They do not come with the soft tip. You will have to transfer that from your stock bolt. They will in the future but they are not in stock at the moment and everyone keeps bugging to put these online for sale.
