This expansion chamber is setting new standards. It has a large liquid cell at the bottom and then 8 micro cells on the top. This grip is the first grip that was designed with both CO2 and N2 users in mind.

The X-Core will give more than enough expansion cell area to break up liquid CO2 while still keeping a straight through, low resistance air flow for Nitrogen. Also, the port hole is on the bottom. Most x-chambers have it on the side and you have to get the hole lined up. With the hole in the bottom, you just get a 90 degree connect elbow (same as with a gas-thru foregrip). Superior performance at a low price makes this expansion chamber the best on the market!
