The 2.6mm thread pitch will fit all 2.5mm x .45 vent rib shotgun barrels.

Tired of losing Your Magnetic Shotgun Beads?

Our innovative taper lock design uses a combination of friction and surface area to securely hold the bead on the barrel. This design will withstand thousands of rounds and last the lifetime of the shotgun vs. current options on the market. With magnetics, you are lucky to get through a hunt without losing the bead. Magnetic sights can also lose magneticity when heated up and shotgun barrels get hot quickly. Our friction lock design is not affected by heat.

A Night and Day Upgrade Over Fiber Optic Sights!

Our standard dot shotgun front sight bead is more visible in bright light than fiber optic sights in the same size category. We take full advantage of our bead footprint and utilize 90% of the surface area with our Ember Glow Dot. The short low-profile design is durable and will not break if hit or discolor with cleaning agents like fiber optic sights will.

There are some longer fiber optic sight options on the market that can offer better daylight visibility, but their fragility increases with the added length.

See Your Sights in the Bushes!

Our proprietary photoluminescent material absorbs ambient light and glows in low light, aiding in hunts with thick overhead vegetation or foggy mornings in the blind.

Designed specifically for hunting purposes, our beads do not contain tritium. Instead, they feature a fully colored glow dot surface area to provide excellent visibility during daylight hunts and ensures adequate visibility during early morning hunts or in thick vegetation.
