Silverback TAC-41 Advanced Hop-Up Kit Installation Guide

This official Silverback video demonstrates how the TAC-41 advanced hop-up kit is fitted, from removing the original wheel and nub to reinstalling the hop-up and inner-barrel assembly. Use this guide when you need to follow the filmed installation sequence and distinguish the low-nub and high-nub adjustment ranges supported by the kit.

What this procedure does

The footage begins by removing the screw that retains the hop-up wheel with a 3 mm Allen screwdriver. The original wheel and nub then come out, while the video specifically warns that the feeding mechanism can fall if it is not secured. The reinforced feeder, selected nub and fine-adjustment wheel are subsequently fitted before the hop-up and inner-barrel assembly is reinserted with the feeding mechanism engaged.

The kit is compatible with the TAC-41 AEG hopup SBA-HOP-30 and GBB hopup SBA-HOP-31. Its fine-tuning wheel has a 500 µm amplitude divided into 50 increments of 10 µm, compared with 15 µm increments on the original wheel. With the low nub, the adjustment range is 0 to 500 µm; with the high nub, it is 250 to 750 µm. The reinforced feeder may leave marks on the nozzle without affecting normal operation.

What the footage makes clear

This walkthrough stays close to the official Silverback source. The expanded notes explain what is visible at each checkpoint, while measurements, compatibility and cautions remain limited to what Silverback actually states.

  • Installation sequence and visible checkpoints are attributed to the official video visual review observations.
  • Compatibility, kit contents, construction details and adjustment specifications are attributed to the official video description.
  • No official or automatic English or French subtitle track was available.

01Remove the retaining screwAt this opening checkpoint, the 3 mm Allen screwdriver is used on the screw retaining the hop-up wheel. The wheel is still in place, so compare the frame with the screw being removed before moving on to the original wheel and nub. This first release begins the disassembly sequence shown in the video. Video: 00:15 ↗
02Take out the original wheel and nubOnce the retaining screw has been removed, the original wheel and nub are taken out. The footage warns that the feeding mechanism can fall if it is not secured, making that mechanism the detail to compare before continuing. With the original adjustment parts removed, the feeder and selected replacement nub can be fitted next. Video: 00:50 ↗
03Fit the replacement adjustment partsThe reinforced feeder, the selected low or high nub, and the fine-adjustment wheel are installed at this checkpoint. Compare the replacement wheel and nub with the parts removed in the preceding view; the choice of nub determines which source-defined pressure range applies. The assembled adjustment parts lead directly to reinserting the hop-up and inner-barrel assembly. Video: 01:50 ↗
04Reinsert the hop-up assemblyThe hop-up and inner-barrel assembly is reinserted with the feeding mechanism engaged. This engagement is the key visual change from the preceding parts-fitting view, so compare the mechanism’s position as the assembly goes back in. The low nub covers 0 to 500 µm, while the high nub covers 250 to 750 µm, depending on the selected part. Video: 02:21 ↗
05Reinstate the ball plungerAt the final fixed checkpoint, the ball plunger is reinstated after the hop-up assembly has been returned. Compare the frame for the ball plunger’s return as the closing action in the filmed sequence. The completed adjustment setup uses the fine wheel’s 50 increments of 10 µm, and its laser marking helps return to the exact same click. Video: 03:31 ↗
Source-stated cautions
  • The feeding mechanism can fall if it is not secured.
  • The reinforced feeder may leave some marks on the nozzle without affecting the normal operation of the parts.
Checks shown or stated
  • The feeding mechanism is engaged when the hop-up and inner-barrel assembly is reinserted.
  • The ball plunger is reinstated.
  • The laser marking on the fine-tuning wheel helps return to the exact same click.

04FAQ

TAC-41 tutorial questions

Which TAC-41 hop-up units is the kit compatible with?

The official description lists the TAC-41 AEG-type hopup SBA-HOP-30 and the TAC-41 GBB-type hopup SBA-HOP-31.

What adjustment range does each nub provide?

Used with the low nub, the fine-tuning wheel adjusts rubber pressure from 0 to 500 µm. Used with the high nub, it adjusts rubber pressure from 250 to 750 µm.

How fine is the replacement wheel compared with the original?

The replacement wheel has 50 increments of 10 µm across a 500 µm amplitude, while the original wheel has 15 µm increments. Its laser marking helps return to the exact same click.
