Product Description

Features

  • Precision CNC-machined, durable aviation grade aluminum construction
  • Allows for the use of Tokyo Marui-spec GBB inner barrels and buckings in your sniper rifle
  • TDC (Top Dead Center) design provides a large degree of control for your adjustments
  • Compatible with the SBA-HOP-34 Advanced hop-up unit
  • All necessary components included
  • Silverback Airsoft bucking included
This TDC (Top Dead Center) hop-up has 0.75mm nub travel amplitude, divided into 50 positions (15 m per click). It includes a feeding system to avoid double feeds, a 60 flat GBB hop-up rubber (SBA-HOP-41), and is compatible with other GBB hop-up rubbers and GBB inner barrels. To accommodate different brands of barrel, it can be assembled either with the barrel clip, or with the 3x M3X6 screws.

Manufacturer: Silverback Airsoft

Note: Because of a different inner barrel position inside the hop-up, this unit require inner barrels at least 3 mm shorter than the AEG hop-up unit equipped with the same outer barrel to avoid your inner barrel sitting outside of the outer barrel:
  • 510 outer barrel requires a 507 mm GBB inner barrel
  • 420 outer barrel requires a 417 mm GBB inner barrel
  • 330 outer barrel requires a 327 mm GBB inner barrel
