Description
05 RAIZEN Inner Barrel for Tokyo Marui M870 Series – 260mm
Designed for the Tokyo Marui M870 series, this 260mm inner barrel is part of the 05 RAIZEN lineup.
Featuring a 6.05mm inner diameter, it provides a moderate amount of clearance without being excessively tight, aiming for a well-balanced combination of range and accuracy.
The barrel is manufactured from SUS304 stainless steel. Using the precision machining know-how developed by da Vinci custom, careful attention is given not only to the bore diameter, but also to the internal surface condition and overall finishing quality.
The 260mm length was selected specifically for the M870 platform, taking into account its unique three-BB simultaneous firing system. It is suitable as an upgrade from the original inner barrels.
Available individually, or as a set of three for users who wish to replace all three inner barrels with matching specifications.
