Add the Magpul K2+ Moe Grip

Add the K2+ MOE Grip from Magpul. Personally, I think the grip looks very unique and would most likely add to the variety of AR grips we have, and depending on stats, would be a very helpful and decent grip for starters.

I think it looks great too, simple to implement and add. I would like to see them add it to a list of things to add in the future after more substantial content and patches have been added for sure ❤️
