Frequently Asked Questions
Will this sight fit my rifle?
This barrel-mounted sight is designed for rifles with a front sight dovetail cut directly into the barrel. Your rifle must have a .450'' wide dovetail to accommodate this sight. Measure your barrel's dovetail carefully before ordering, or consult your rifle's documentation to confirm compatibility.
What's the white bead made of?
The front bead is white polymer, 1/16'' in diameter. It provides good visibility across a range of lighting conditions and won't corrode like some traditional materials.
Is this sight alone enough for aiming?
This is a front sight and requires a matching rear sight to form a complete iron sight system. You'll need a compatible rear sight installed on your rifle to establish a full sight picture for accurate shooting.
Can I remove this sight if I switch to a scope later?
Yes, the dovetail design allows you to remove or replace the sight if you transition to optics or want to swap it for a different model. However, removal and reinstallation should be done carefully to avoid damaging the dovetail cut in your barrel.
