Hand selected Version 2 Black Python 407mm Tight Bore Barrel for M4 / SR16 / SG551. The Black Python is a tried and tested product. By using a hard coating process, the barrel can provide the smoothest inner barrel surface and reinforced structure. Madbull QC each piece of barrel by a very special process, every single barrel has been carefully chosen and well-packaged.
What is different from Ver 1 and Ver 2?
Based on the feedbacks from users, Madbull did a lot of improvements on the Version 2. For Version 2 a new machining and new coating process was used. The Version 2 also has a different packing (10pcs packing) process to prevent "bending" during shipment.
