MagnusHD Barrel for PTW / length : 16inch(448mm) The Wide Bore Barrel for Professional Training Weapons (PTW) is here at last! The Teflon coated 6.10 MM diameter wide bore inner barrel reduces friction and resistance achieving precision accuracy! --- About ORGA Barrel --- After our first lot became a hit with players in Japan, selling over 2500 units in 2012, we are happy to announce that our second batch of ORGA Magnus WideBore barrels has arrived with a new and improved design! As shown below, a standard diameter barrel will introduce some friction and path variation due to slight contact along the length of the barrel. This can have a significant impact on BB trajectory and accuracy. Longer barrels and increased hop are often used to try and reverse these effects.
