Laylax Nine Ball Power Inner Barrel for Gas Blowback Airsoft Pistols (Model: Hi-CAPA 4.3 / 94.5mm)

"6.00 gives supreme shot to shot consistency, especially when paired with heavier weight bbs. This barrel with a decepticon/I-key and .28s gives /- 1fps consistency and a wildly flat trajectory out of a 4.3. PDI is the only brand to consider when looking at barrels, especially so at the .00 range. the only real downside is that these are pretty picky bb wise, garbage ammo will jam up a 6.00. any amount of dirtiness can foul these barrels so a clean system and environment is kind of a requisite. for most players, something like a .03/.05 would be the more practical option.
