Thanks to a kind customer on Gunbroker, I obtained measurement for the top rail of a 8 inch launcher. I winged the modeling based on his one picture tape measure data so this top rail may not fit perfectly (very slightly too long or short), but I assure you it will fit and function.
Also, I slightly tweaked the geometry of the stock adapter itself because my G36 stock supplier seems to change the mold every time when I purchase from it. The new adapter should hopefully fit better with G36 stock purchased from Evike after May 01, 2022.
