Wheeler Anti-Cant Indicator Picatinny Rail Attachment - WH 580033

This anti-cant indicator mounts to a Picatinny rail and helps ensure your scope is perfectly aligned to prevent canting errors that affect long-range accuracy. Even minor angular misalignment of 2-3 degrees can cause significant point-of-impact shifts, making this tool essential for shooters using drop-compensating scopes. The indicator helps verify proper rifle alignment before dialing turrets or using hold-over marks.
