Product Description
The Spark II is one of the first compact sights that HIVIZ developed and remains a top seller today. It’s tiny but brilliant with an affordable price tag. Unlike the Spark III, the LitePipes are not interchangeable, so make sure you pick the color that best suits your needs. Use the drop down to select Green or Red. This sight sells for $11.05 on the HI VIZ web site store
Fit Details: Fits most vent-ribbed shotguns with removeable front bead. Sight includes five screws in varying thread sizes to fit nearly any shotgun: 3-56″; 5-40″; 6-48″; 3mm x .5; 3mm x .6.
I can only speak to Remington barrels so here is some info. Remington Non Vent Rib Bead sight barrels are pressed so this will not work on them. Remington Vent Rib barrels all models are 6-48 Threaded so this sight will work on them.
