PDI 6.03 Precision Inner Barrel for AEG 208mm

The 03 barrel has a tight inner diameter and is a model that emphasizes on FPS. It is a precision stainless steel barrel made by cold forging. Since the inner diameter is slightly wider than the 01 barrel, it is less likely to get jammed with sand, dust and wax compared to 01, and it requires less maintenance. However, do be sure to perform regular maintenance just in case. Outer Diameter：8.55mm Inner Diameter：6.03mm Tolerance：±0.002mm Material：SUS304
