This is NMS-GnK, quite simply its alternative parts for MS-GnK to give it a less aggressive silhouette, for those who do want a fresh gnk but don't want a milsim appearance!

This is fully interchangeable with stock MS-GnK parts, requiring no changes to electronics or firmware, making this a fairly simple conversion, only a few added pieces of hardware.

The stock utilises an AEG attachment point, similar to the ones used in Airsoft, with a single M5 bolt running through to the M5 nut thats included on the original MS-GnK. I can comfortably fit in a GnB 3s 1700mah 60C LiHV battery, utilising the wire channel at the bottom of the stock. 

Most of the hardware is what is included in MS-GnK and whichever attachments you used for it, but the extra pieces of hardware are as follows:

• 2x M2x8mm Bolts (For stock buttplate)

• 1x M3x15mm Bolts (For foregrip + upper shroud mounting)

• 1x M5x15mm Bolts (For stock to receiver mounting)

• 1x 5mm OD x 4mm H M3 brass heat insert

• 1x M3 Thumbscrew (For stock and/or grip)

• 3x M3 Hex Nuts (For stock)

No further modifications to MS-GnK are required. You will still need to supply your own grip, however there are many 3d printed and aftermarket options out there.
