Saber Tactical Arca Swiss 2 Accessory Rail ST0022 with with Picatinny rail at the end.
This Arca Swiss 2 accessory rail from Saber Tactical is the successor to their first Arca Swiss rail. The difference is that this version has T-slots on both sides to mount flashlights, lasers and other accessories.
Saber Tactical has made the rail from sturdy aluminium (6061 T6) that has been anodized, which makes it wear-resistant. The edges have been smoothed off so you can shoot your FX Impact off-hand.
All features of the Arca swiss 2 accessory rail:
Arca Swiss as the main rail
Picatinny rail on the front
Screw hole with ¼x20 thread for conventional camera tripods
T-slots on both sides
This rail comes with one extended fill cover cap
