Picatinny rails are a type of mounting platform used to attach accessories to firearms. They provide a large surface area for mounting rings. If you can't get the correct eye relief with a two-piece set, you can move to a different slot on the rail.
Here are some other reasons to use a Picatinny riser:

• Improved line of sight: A riser can provide a clearer line of sight for night vision goggles.
• Shorter distance to move weapon: A high riser block means the shooter has a shorter distance to move the weapon to achieve the mounted shooting position.
• Reduced muscle fatigue: Low-mounted optics can place excessive stress on your neck and eye muscles.
• Comfortable and safe shooting height: A riser can lift your optics to provide a clear view over the front sight.
