Nathstratford Posted September 16, 2021 Posted September 16, 2021 Right, so I a want to get a 417 GBBR after using my mates KA sr25. But I'm not sure if they come npas or a valve to change fps. Any help would be great guys :)) Cheers
sjhirst Posted September 16, 2021 Posted September 16, 2021 The VFC? Most will not include a way to downgrade the fps, so an npas or fg-airsoft lfs disc can be used.
