The Grind Right Square Gap to Rail was designed specifically to pair with the Blackriver 5-Stair, but it can also be incorporated into custom DIY spots and projects.
When mounted to the Blackriver 5-Stair, the rail installs in a slightly different location than the original Blackriver rail. This allows the stock rail to be reinstalled later without any extra modifications or hassle.
Please note: The Blackriver 5-Stair is not included.
Like all Grind Right products, this rail is built from 100% cold-rolled steel and TIG welded for excellent durability and a realistic feel.
