Love this handy little pcp!
After some minor polishing of some rough parts and fitting a weaker trigger spring, it performs great.
As mine is FAC, it is rather loud dispite the build in silencer, so I ordered a adapter to fit a Weihrauch silencer, now it is super quiet.





Because I tinkered with the hammer and spring, there was to much force put onto the valve stem and the plastic part broke!



I altered the design slightly to make it stronger, now it is fine!
