I'm putting together an F Class rifle. Rifle will only be used for these competitions. Just installed a Riflebasix Sav-2 trigger. I understand all of the adjustments and have adjusted accordingly for a very light pull. Also using the red spring. Here's my question, is it normal for a trigger when it's set down in the ounces range to trip when doing a bump test? It doesn't go off on it's own, or when the bolt is cycled, etc. Just when doing a bump safety test. If it isn't I'll probably need to adjust the sear engagement screw. Please advise. Thanks to all in advance.
