Currently these are only available the
smooth styles seen. Can help get rid of or reduce bolt stick just from the

cap.

  can see a 15-25fps increase. Co2 results are less.
  
• Higher volume means you can run a lower
  operating pressure
  
• Using our high volume cap alone on a stock
  Impulse can eliminate or reduce bolt stick completely during dry firing

  the stock capacity of only 9.6cc.
