Already some time ago LCT Airsoft introduced the Slim motors and handle for the LCK 47 series. Due to the narrow motors the grips could be manufactured much closer to the original. The next logical step is of course the more modern versions of the LCK 74 series. They are suitable for the models LCK-74, LCKS74, LCKMS, LCKS74UN and many more.
Of course they are also available in different colours. Black, bakelite-look and dark red. You can find out more at LCT-Airsoft (click here).
