This is FN5-7.Marui has already announced last Hobby show(1 years ago).They said A development of New AEG (M4 & AKs)had taken a long time.So the release of L96 & FN5-7 were delay.
That cylinder bore is the 2nd biggest of all Marui's pistol,so has really hard shock with blowback.(No1 bore is Desert Eagle)
Under rail is adopetd Picattiny.
They emphasize it & demonstrate attached some lights.
I feel heavy shock more than TM HI-CAPA series ,so nice pistol.
