"Using this (208mm) in an ICS CXP15 and have very good luck. Comes right a bit past the end of the threading of the outer barrel but can confirm not so much that a tracer unit cannot pick up the shot (tested with the AT1000).

Very consistent shot and didn't see a big jump in fps (about 5 to 10 ish) which is a pro to me as it didn't push my gun outside my locals strict fps limits.

"Pretty solid upgrade for only $30 the consistency improvement over a stock brass barrel is massive.

"I was thinking about getting R-Hop for my gun but because it was a little bit out of my budget I went with this. This inner barrel works magic, the bbs go super far and super straight. Would definitely recommend this for people who are trying to increase the performance out of their AEG.
