Eliminates the farting, and made my pump stroke smoother!
A bit Pricey, but well worth it
It basically completely changed the way my gun shoots and feels completely. The pump stroke used to be tight and jerky but is now smooth as butter. My pump stroke is 100 times smoother and the farting is gone. I have not noticed any efficiency changes, but it does sound quieter as well. The lower tube kit and CCM pump kit are a must have for any pump I own.
I would suggest anyone looking to improve the performance of an autococker or sniper to pick one up. Though expensive, its CCM quality and THAT makes it worth it as anyone who has used their products can agree.
psychoballistics superbolt, psychoballistics z drop, CCM inline reg, Emprie 4pc barrel system, 12v revy, CCM internals, front block, Back block, and CCM Bolt
Every thing it's well... perfect
Well i have been looking to get and upgrade for my gun. Well CCM did it again with this one. These internals are the same as what is in the J2 and the Series 5 as far as i know. They allow for better airflow and less air usage I have noticed a drop in the amount of air the gun use. Granted i could have a better gun to be putting these in but hey im slowly putting what i will be calling the MINI CHIP together.
