They Look Cool At End Of Barrel, But Friend Tried One Out Missed A Turkey, And He Really Never Misses Unless To Far, He SHot At Some Toms That Were Running Away From Him, Hit His Back..Later He Was Wondering...So He And A Friend (Had A New Sight New)(Ring Or Fire)
He Targeted And He Missed Paper At 30 Yards. (Granted He Misses Alot)
So Then They Toke Of Sights And Used Beads On Barrel And It Was In The Head/Neack Area 50 Yards. One Gun Was A Remington 870 And A Mossberg 835.

What Problem Was.....

Problem Was That The Sights Were Higher Then The Bead And Therfore Your Gun Barrell Is Basically Droped So At 30 Yards Missing A Huge Paper Turkey, Is About 1 1/2 FT Drop At 30 Yards...
This Was Same On Both Guns.
But Because The Sights Were Higher Its A Miss, And Thos Sights Are Un Adjustable.
