5KU Low Profile Mount for VFC MP5K GBB ( 5KU-420 )

If you like to mount any red dot or optic on the MP5 this is a perfect fit on the VFC/Umarex MP5K GBB. Be aware this is the low version of this attachment, so when you use a red dot you won't be able to use the iron sights unless you have an elevated red dot with an open space under it.
Highly recommended.
