<p><br>this package is for the FGC9 MKII, MKIISD<br>and the MKII MKIISD models of the FGC6 (FA,S) lineup<br>and the MKII version of the FGC68.</p><p>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.</p><p>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.</p><p>print wise, normal FGC9 settings will work. 0.16 layer hight is fine enough for the treats to work.</p><p>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</p><p>movie link<br><a href="https://youtu.be/vfE4TGeNW_Q">https://youtu.be/vfE4TGeNW_Q</a><br><br><br>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.&nbsp;</p><p>__&nbsp;<br>what does the MKIISD update mean?</p><p>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.</p><p>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.</p><p>and wile I’m add it did I also add the grove that prevents the barrel from rotating</p>
