What exactly is an FT gun anyway
? I can think of only a very few rifles that were designed specifically with FT in mind. The EV2 springs to mind but even that has origins way back to the RN10/RWS CA100, which may or may not have been designed with 10m in mind, depending on which you understand to have come first.
Steyrs, Walthers and the like certainly don't qualify as they are nothing more than adapted 10m rifles.
