Vector Optics SCRA-58 Short Picatinny Riser — Black

The Vector Optics SCRA-58 short-profile riser is a height adapter for Picatinny rails that raises optics, red dots and sights by 12.7 mm above the base rail. It is intended for shooters mounting an optic on AR platforms with a low comb, elevated handguard, or any configuration where standard eye height is too low for a natural cheek weld and sight alignment.

The 12.7 mm height corresponds to the offset needed to bring a red dot or scope into direct co-witnessing with folded iron sights on AR configurations, without replacing existing rings or mounts. This is a precise, functional value: it keeps the backup iron sight line operational without adding so much height that the optical axis moves meaningfully away from the bore axis.

The short profile is a deliberate compromise: it takes up minimal longitudinal space on the rail, leaving room for lights, lasers or other accessories, while adding no height beyond what is required. Anyone needing a greater lift should consider a high-profile riser instead. The anodized aluminium body withstands recoil on high-impulse calibres and does not develop play over time, keeping point of impact consistent between sessions.

Key points

• Height of 12.7 mm for direct co-witnessing on AR platforms with folded iron sights
• Short profile: clears the rail for additional accessories without unnecessary added height
• Compatible with any accessory using a standard Picatinny mount
• Anodized aluminium body: maintains point-of-impact stability even on high-recoil calibres
• Uniform matte black finish, suited to outdoor use in wet and dusty conditions
