- description
Adjusting hop by feel is how people lose an afternoon. The tool goes in through the chamber area, and its built-in positioning lugs locate against the unit so the adjustment you make is the one you intended rather than a guess with a flat-blade.
It is steel, so it will not round off on the first stiff adjuster, and it is cut for VFC’s newer TDC hop-up unit specifically.
If you shoot a VFC gas rifle with that unit and you have ever chased a flyer around the range, this is the part that turns the job into thirty seconds.

Good to know before you buy
TDC stands for top dead centre, the vertical adjustment on the hop unit. This tool is for setting that, not for replacing a hop rubber.
Make one adjustment, then shoot a group before you touch it again. Chasing hop in half-turns with no shooting in between is how you end up back where you started.
Frequently asked questions
Will it work on an older VFC hop unit?
It is specified for the newer TDC unit. An older chamber may not have the features the lugs locate against.
Do I need to take the gun apart?
No. Access is through the chamber, which is the point of it.
Does it fit other makers’ hop units?
VFC name their own TDC unit and we are not going to extend that.
Is it one tool or a set?
It is listed as a tool set for the job; VFC do not itemise the pieces.
