The phone nunmber to customer service goes to Bushnell. They are as helpful as nipples on a boar hog. No instructions worth having with most of Bushnel's newer stuff. The Uncle Mikes mag pouches came with extra parts but no instructions as to what to do with them. Sad, very sad.
Pros: adjustable tension
Cons: No instructions on the extra parts.
