I have the older style FX impact in 30 caliber. I just received my impact X Barrel 30 caliber my question is when I do the barrel swap I know I will have to re sight the scope but do I have to mess with anything else or can I just swap it and be done with it? BTW the new Barrel isn't a 700 mm it's the same size as the one that was on there the only difference is it's an X Barrel
If it's the same length, 600 mm as the original not much should change. My son put the 700mm on his and it did increase the fps some.
I have a replacement 600mm X barrel, too, although mine is .25. Since I got it, the temps have been TDH to sit for a few hours testing it to see if the gun needs to be retuned. New indoor range will be wonderful when it finally opens.
