463mm MLOK Hex Handguard

thingiverse

The barrel nut screws directly into the upper receiver. The handguard locks onto the barrel nut, held firmly in place by two or three M3x0.5x12 screws. If you prefer a shorter model, simply slice it down to size, then smooth out the edges with sandpaper and seal them together with superglue. Printing this design at 0.2mm layer height with 200g of PLA filament can take around 22 hours, depending on your printer settings.
