I suggest searching instead on QB trigger and you should get lots of results.

The trigger group is light years ahead of virtually any rifle on the market at a $100 price point.  Fully adjustable for pull weight, sear engagement, and overtravel.  All it really needs is a smoothing and lubrication of the contact surfaces and it works great down to even a few ounces.

[edit] Oh, I also meant to mention that shimming the trigger blade with M3 washers improves both the smoothness of the pull and gives a much better tactile impression by taking out the side-to-side play.  [/edit]

If you want, you can install a spring plunger and convert it to a 2-stage type.

There is a part available from airguns of Arizona that converts the AR style trigger to 2 stage function, however caution must be taken as "balk firing" is possible due to the lack of reset capability.  Balk firing is usually limited to springer discussions, but it applies to this mod as well.

Someone had posted a trigger mod using a spring plunger from McMaster Carr.  Not sure which one.

Hey Tennx,
As Jason has suggested, it only costs a few buck to lube & modify (lighter trigger compression spring), smooth metal contact points and you get a trigger capable of some fine shooting.  No need to spend mega bucks; that's part of the charm/value of this gun.

Hey guys,
I already lubed mine and I am thinking of replacing the spring with a lighter one, what would be your opinion on the single stage QB's trigger? Is it worth to add a 2nd stage?

- Lighter spring on trigger ..... makes it so nice 
- Nope
