I found that the release on the MDT LSS Chassis system could be enhanced and could not find any solutions for it. I designed this one to slip onto the factory release and be held in place with friction. In addition, a hole can be drilled and tapped to accept a bolt for a more secure install. The user can drop a magazine easily with minimal movement using the index finger or support hand.
I printed using Colorfabb XCF Filament at 100% infill in simplify3d. I suggest printing in PLA first to scale to a proper fit, then printing in the desired medium.
