3D model description

this lower top rail will work with your stock FGC9 MKII,FGC6 MKII and FGC9 MKIISD Uppers.

this model is made to go in place of the stock top rail that goes with your MKII. in case you have a different shroud model then you might need to look for a different rail piece. those are usually included with the shroud middle in case it needs a different one.

how to mount these these work with the Flat Countersunk Head M3 Screws in a lengt of 14mm

also note that this rail is a lot thinner so it looks to be really weak and flexible even when it is a lose part, but once it's bolted on the upper does it get its structure.

I have added 2 extra low rail options. MID 1mm, MID2mm, just incase you find that the stock Low rail is to low. then the MID 1mm will add 1mm and the MID2mm 2mm to the rial hight.

or go for the fixed rail options
