Default Re: review of smart parts 20 inch linear barrel :mad:

When you say you were "messing with the velocity," were you over a chrono? A barrel that long can often require a higher input pressure to achieve the correct velocity. If yours was outside 280-ish fps by very much, either high or low, odd paint trajectories can happen. The stock barrel is about 10" so that may be what was happening.

Try the barrel again, this time over a chrono, and see if you can't get the barrel dialed in.
