Compared to firearms, projectiles fired from paintball, Nerf, and crossbows have a very sharp drop. This can make buying optics difficult - most can't have the elevation dialed so far down!

These rails add or subtract an extra 1-3 degrees of elevation, putting that garbage $20 Amazon scope back on target!

The 2.5- or 3-degree rails are perfect for high-performance Nerf blasters. Paintball markers and crossbows may only need the 1.5- or 2-degree rails.

The creator also included an extended 3-degree rail! It's a long boi.

I recommend printing these on the end for strength. You'll need two M5 lock nuts and two M5x30 screws.

This worked great for my Caliburn Sniper build on YouTube!
