"Great Quality barrel, for being a Japanese steel product it is cheaper than other options. I have the 595mm length and its current installed in my SRS. And being a bullpup, the barrel only sticks out an inch from the outer barrel.
Regardless, it’s a great barrel and worth getting. I have bought a few different Lambda branded barrels and they have all be consistent with the crafsmanship and quality.

"These is a solid inner barrel for the price. I got the 303mm version and it shoots lasers. Be advised it has a slightly larger outer diameter than your brass barrels (Only by a few nanometers). They'll still fit in your hop up and outer barrel but it will be slightly more snug but nothing to worry about.

"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.
