Inokatsu apparently decided to produce its own gas blowback rifles instead of simply releasing body kits for the WA M4s. As a matter of fact, Inokatsu will release different rifle series under its MTW (Masterwork Training Weapon) product line. The first of the series is the M4 SOP MOD0, planned for release at the end of August, with a MSRP of NTD 17,800 (USD $585.62). Inokatsu will also have two gas systems available to cater to the different markets. One is designed for common gas propellants (HFC134a and propane). The other is designed specifically for CO2 use. Inokatsu will demonstrate and take preorders of its MTW M4 SOP MOD0 line at the Taipei Hooha Show (August 8th to 10th).
