Description

This model features a replica of the GBRS Lerna Mount. I initially thought this sight riser was a bit much, but it has a strong use case if you have an A2 front sight gas block or if you are into CQB/CQC. This sight riser allows a full sight picture of your back up irons even if you have the beefy A2 front sight post seen in one of my pictures. It is designed to mount to picatinny rails using M3x30mm hardware. I have limited data on mounting plate footprints so I have only designed the ones that I had info on. If you want a different mounting footprint, leave a comment or send me dimensions and I will try to help you out.

Mounting Footprints/Scope Compatibility:

-Aimpoint Acro

-Sig Romeo

-Any Scope that mounts to Picatinny Rails

-Any Scope with the same footprint as ones listed above

Hardware Requirements:

2 - M3x30mm Screws

2 - M3 Hex Nuts
