ZCI's latest generation of stainless steel inner barrels are very well made and feature some ideal features for an aftermarket barrel. They are cleanly cut and the internal surface is visually comparable with high end brands. The hopup window cuts vary a bit for different barrel in these, this is because there are a few different types of windows used by different brands and makes of GBBs. Please compare the window cut shown in the picture below with the cut of your stock barrel to ensure compatibility. The crowning on these barrels varies, some are rather deep and some are very shallow (see pictures below). As with all aftermarket barrels please clean these thoroughly with a strong solvent followed by a light coat of silicone oil before use to get optimum performance.
