FGC9 FGC6 FGC68 MKII MKIISD UNW free floating handguard

this package is for the FGC9 MKII, MKIISD
and the MKII MKIISD models of the FGC6 (FA,S) lineup
 

this “rail sizer” to make your AR15 shroud look better. will most likely not fit your model. but with some help of others there maybe some more designs added on a later date. but it should not be so hard to make a rail sizer on your own. so I hope mine can be at least be a bit of a inspiration.

keep in mind that the barrel retainer with the mount for the free float shroud will take in some extra space shown on the picture. and the barrel sits a bit further back. so make sure your shroud is not getting to long.

print wise, normal FGC9 settings will work. 0.16 layer hight is fine enough for the treats to work.

for the riser you could go for 0.2 layer hight and a 8 wall layer thickness with 40% infill. but it depends on what your are planning to mount on it… you don’t want your sling mount to break on you

I have added a pressure pad under the rail option as a concept. but this might be a bit hard to press with gloves or thick fingers. but it's doable.

what does the MKIISD update mean?

the main update and why these are called MKIISD are that I took some improvements from the FGC9 SD and placed in the MKII shroud models that I designed. but keep in mind the are still made to just work with the MKII this is because the rail stands higher then the SD does.

so the magnet design of the MKII have been removed. and the SD style magnet have been added. the to install it is basically the same. but you will be using a cylindrical magnet with a OD of 5mm and 10mm long in size.

and wile I’m add it did I also add the grove that prevents the barrel from rotating
