The new HAND SELECTED Version 2 Black Python BP229 229mm Tight Bore Barrel. For long barrel custom AEG's

By using a hard coating process, the MB barrels provide the smoothest inner barrel surface and a reinforced structure available.

MadBull QC's each barrel by a very special process, every single barrel has been carefully hand chosen and well-packaged from the factory to ensure accuracy.

What is difference between Ver 1 and Ver 2? Based on the feedback from users, MB did a lot of improvements on the new Ver 2's Ver 2 is being made with a new machining and new coating process. Ver 2 is using different packing from the factory to dealers (10pcs packing) to prevent "bending" during the shipment.

NOTE: The choice of B.B.'s is very important. MB barrels are 6.03mm in diameter, all BB's available for sale at Gamepod have been selected based on consistency across production runs and extensively tested in tightbore barrels down to 6.01mm for proper clearance.
