Everything about this bolt is perfect. My velocity at the chronno went up when I installed this, not to mention my accuracy is notably better. There is less kick with this bolt, and the airflow is perfect through it. The range on my gun is much better also. It will quiet your impulse a little, and really improves on every aspect of your performance. Definitley one of the best Impulse upgrades you can get.
Conclusion:
Buy this bolt. There is not one disadvantage with this bolt. it is perfect in every category. I personally have not seen any other bolts for the impulse that even compare.
