Chinese Beeman" Breakbarrel - Mods.

[SpiralGroove]

Hey Guys,
I have a friend who has a Chinese "Beeman" breakbarrel that looks to be 5/10 years old.  Its a .177 caliber (not duel barrel).

Question:
The trigger on it is absolutely Terrible.  Without pulling off the stock it looks Non-Adjustable.
Does anyone have any tips on making this trigger lighter.  I have tuned many triggers including Rekord, AA, Hatsan and BAM triggers.  Is a Charlie De-Tuna trigger useful on this?

Any help is appreciated before I dig into this one .

Well ............ found two good sources:  Should be fairly easy .

You're not giving much information.  Does the gun have a model number of any sort?  Is it possible to get a picture - especially of the trigger mechanism?

You could probably get a lighter pull simply by polishing sear surfaces.  Lighter springs in some areas could be a possibility as well.

Yeah Roadworthy,
Looks like we have two trigger adj. screws, a trigger pull screw and a sear spring which could be lightened.  Some polishing always helps.
The gun is almost un-shootable in its present form.  The stiffest trigger I've ever pulled .
