This is a replica of the 45 degree version of the product of the same name. For now it contains mounting plates for RMR, ACRO and T1/T2 pattern optics (The T1/T2 plate has 2 versions, with/without the recoil lug), since those are the only 3 patterns I'm familiar with, whilst the real thing can accommodate dozens of footprints.

Hardware needed: 

• 1 M3x30mm screw to attach the mount to a picatinny rail
• 2 M4x10mm countersunk screws to attach optic plates to the mount 
• Whatever screws are needed to mount your optics

It's best that you print this with a strong material and high infill.
