Front Sight for GBB 17/23 TM/KJW/WE. Attention: FIBER OPTIC NOT INCLUDED! It fits a 1.5mm fiber optic rod! I advise you to get aome UAC 1,5mm fiber optic, they are the best out there. Or some RS ones.
The fiber optic will be very bright because in this design it can catch a lot of light!
Works very well in conjunction with one of the rear sights that I sell in my shop!
