Yes. But from what I understand about the AGM VSR clone at some point the trigger sear is going to break and need replacing, so unless the whole trigger / barrel assembly can be removed from the woodwork, that's going to be difficult.
Not that I am complaining mind ! Ace job so far.
Replacement trigger sear is £35 at Zero One. I'm not sure if that solves all your issues.
There was a suggestion from someone that the issue with mine could be the spring guide or possibly just a loose internal screw around the piston - not sure tough as you hae the rifle I haven't been able to look 
I've heard the AGM isn't a direct clone of the TM VSR, like the JG bar-10 is. Internally its slightly different. A friend has tried to upgrade his in a past. The parts he bought didnt fit.
In the end he went and bought a TM VSR, as it was easier.
