FGC9-MKIISD UNW370 SLIM shroud or for the FGC6 MKII

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

--

the name 370 stands for the barrel length this is made for. but this is the same length as what was called the XL shrouds in the past like the: 2021 LB XL, 2021 LB M XL, XM8 LB XL, TEC9 XL, LB XL.

for the barrel? you can use the ECM v3 set that can be found here https://odysee.com/@c0ld_d8rk_h8nd:8/ECM-Barrels-v3.5:e

materials needed: for the front of the shroud 1x M3 bolt 20mm long or up to 26mm

for on the top rail 4x M3 bolt 20mm long
