WE desert eagle which can fit an npas in it. It fires at 355-356 fps apparently as i've seen in multiple videos so I was wondering if an npas is precise enough to reduce about that much to 350 which is most site limits for pistols.
If it fits the NPAS then yes... but if it'sd firing that close to the limit I'd suggest swapping to a lower powered gas, it would bring it well within the limits, especially when it's hot!
