I'm constantly making updates to make it fit. Right now it's still not wanting to fit right... I will let you guys know when I successfully get it to fit like a glove. Latest Update: 2/25/18
I couldn't find a stl online so I made one. This was modeled to the same dimensions as the one that came with my AR stoner ar15 upper receiver. It should be standard for all 6.75" handrails.
I designed this to have 3 rails so you can have a foregrip on the bottom, as well as 2 more attachments of whatever your heart desires so that it does not obstruct your view. Print the top piece concave upwards to minimize the support structures needed and reduce printing time. Bottom one's rail will look better if printed concave down.
For obvious reasons, don't print with PLA. I'm personally printing mine with PETG. Polycarbonate, ABS, and NylonX are all good alternatives.
