There has been good news as of late. Without doing any porting and/or permanent changes, I have been able to increase velocity from 740fps to a whopping 812fps with just an FX liner/barrel kit from c88machining on ebay.
This was achieved with a 700mm liner while the 500mm liner gave a solid 800fps.
In the near future, I will be modding a brand new Notos with full 5mm porting through all the receiver, air block and transfer port, the custom made thimble will utilize multiple ports for full use of all the new air.
The wanted result of all this will be to make a modular, easy to build, step by step, full power air rifle that will reliably shoot at 100y with the pellet or slug of choice within the confines of the available magazines.
