Tooling Marks on SIONICS NP3 Coated Bolt Carrier Groups

Due to the inherent nature of NP3 coating, tooling marks may be present on the SIONICS NP3 Coated Bolt Carrier Groups. Tooling marks are cosmetic and have zero effect on function.

NP3 coating is a thin, impregnable coating that bonds to the host material. This makes it much less forgiving of tooling marks than other coatings, such as phosphate and nitride, which are thicker and darker.

Despite the presence of tooling marks, all SIONICS NP3 coated bolt carrier groups are backed by our lifetime warranty. This warranty covers any manufacturer defect that would affect function.

If you have any questions or concerns about tooling marks on your SIONICS NP3 coated bolt carrier group, please do not hesitate to contact us. We are here to help you get the most out of your firearm.
