This latest batch of ZCI barrels as a rougher surface finish in the chamber, most of them look like it won't noticably effect perfomance but some of them are not up to my standards so I'm boneyarding the whole batch.
All boneyard items are no returns and no warranty of any kind!
ZCI's latest generation of stainless steel inner barrels are very well made and feature some ideal features for an aftermarket barrel. The window is a good depth and shape for R-hop installs and the internal surface is visually comparable with high end brands. This barrel also features a groove with an O-ring near the end of the barrel for stabilization in the outer barrel. These are all the new edition versions that have deep crowns and double alignment slots so they can fit both normal and TM M14 style hopups. As with all aftermarket barrels please clean these thoroughly with a strong solvent before use.
Remember for improved accuracy these barrels can be lapped with our lapping service developed in cooperation in HS-Armory.
