Hi all, is it technically possible to change my FAC .177 air rifle into a .22? I mean, can i re-barrel it etc, then ask/inform my FEO to change my cert on a variation keeping the same serial number? I know some will say why? just sell one and buy another but i have 2 rifles of the same make, one is a .177 fac and the other a .22 non fac and the easiest way for me to get what i want, (.22 fac air) is to do a barrel swap, along with a few other bits.
Its a clerical/legal answer, not a technical one I'm after. Thanks everyone.
