ZCI 6.02mm Stainless Steel Precision Tight Bore AEG Inner Barrel
(Length: 407mm)

"This is a great barrel. I got the 509mm for an AK74. Dead straight and sturdy with exact dimensions. Significantly boosts power and accuracy. I highly recommend this barrel (=

"These barrels are fantastic. I have a 247mm in a short m4 and 363mm in a g36k. Combined with a maple leaf mr hop, these have become lasers. Accuracy down range has increased considerably along with a 15-20 fps boost from a stock barrel. The range isn't extended much soley from the barrel, you get more range from using a heavier bb and turn up the hopup, which you can do because of the extra velocity. Highly recommended for all builds short or long

"Swapped this into an old M4. I went with the 300mm version. Seems to work great. Paired it with a 4UANTUM friction pro bucking. Brought some life back into the old build and is making me rethink going with a barrel that's 3x the price in my new build. I can't see how it could get much better. It's my first ZCI product and I can see why people like the brand so much. Excellent value.
