Lambda "SMART .03" Precision Carbon Steel 6.03mm Tight Bore Inner Barrel for Tokyo Marui Spec AEGs (Length: 303mm)

"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.

"Alright I've sent about 10k+ rounds through this barrel now and its honestly a quality barrel. It made my groupings alot tighter and made for no random flyers. Comparable to a madbull or Prometheus barrel 👍

"Very nicely polished internally, A great barrel for increasing precision on any airsoft gun. You really can't go wrong its cheaper then madbull 6.01.

"I'd heard that the window for the hop-up bucking on this barrel is rather sharp, which turned out to be true, but it hasn't caused any issue or cut through my bucking yet. Aside from that it seems pretty good. Shots are consistent with my flat hopped Krytac CRB.

"Hmmm...after installing this barrel in the same manner I've installed countless others, using the same hop up unit and Modify bucking, I started having feeding issues.. I did some careful investigating and troubleshooting to determine the cause and discovered this barrel actually sits too far into the hop unit, causing the bucking to protrude a bit too far (we're talking a 1/2 millimeter) into the feed tube, and thus blocking the BB's from feeding out of the magazine smoothly. The slots for the C-clip are very slightly out of spec (VERY slightly) and thus the barrel sits too far back in the hop unit. I was able to correct the problem by removing the hop & barrel, pulling the C-clip, pulling the barrel forward slightly out of the hop, re-setting the C-clip and clamping it gently with pliers to make sure it was good and tight around the barrel. So far it's back to firing properly with normal FPS, but I have never experienced this with any other barrel. A side by side comparison with other barrels showed that the position of the C-clip slots are indeed slightly off on this barrel. Again, SLIGHTLY different, but that's all it takes. I'll stick with tried and true Madbull barrels from now on.
