Ditch the NiB and go w/ Nitrid3 Syt3ms


After use the N3- BCG I have no complaints. They're extremely reliable, consistent, and the quality is second to none. I've ran this BCG full auto and it didn't miss a beat. The salt bath finish allows for the BCG to be cleaned with ease and doesn't discolor over time either.
