Angled Weaver-style or Picatinny-style scope rails elevation �pre-load� are commonplace these days. But most angled scope rails are non-adjustable. Worker MOD offers a more sophisticated solution � an adjustable scope base that allows the nerfer to �dial in� up to 7mm of vertical. The system works via a horizontal rotary adjuster with0-4mm range, positioned on the rear of the unit. The base can be mounted on any nerf blaster fitted with a full-length Picatinny Rail.

This scope base can fit on any 21mm width rail, vertical adjuctment range: 0-7mm, horizontal adjustment range: 0-4mm
