"it works fine for the g18c the only problem i find is when i put any barrel attachment other than a really light piece of plastic or metal so i cant use any tracer units sadly but best in the other respects.

"Still works well for me despite having to dremel and sand the top hopup housing enough for a very smooth action! Touched it up afterwards so it almost looks like nothing happened! If the G18C slide gets stuck, I recommend turning it upside down, and dremel and sand the flat ends of the hopup housing until it no longer becomes stuck. There are other reasons why the slide can get stuck though.

"Sadly, after relatively few uses this outer barrel is starting to fail similarly to the stock VFC one.
I run this in an EF G17 thats been HPA tapped. I run at ~85 PSI, to to acheive roughly 1 joule ouput for CQB (equivalent to roughly 330 FPS w/ .20s)
This amount of pressure should exert less stress on this part than running green gas will on a moderately warm day.
Cracks in this component have already started to appear in the same location they appeared on the stock EF outer barrel, where the square portion tapers into the cylindrical portion.

All in all: it looks good visually, although it defintely looks more like a cast part than a CNC one. The thread are definetly 14mm ccw. And it runs well for a couple games until it starts to fail.
