I’d say you may have had some movement. Best to be safe and confirm zero. Worst case, you just zero it again

If the optic or front iron sight you zeroed is on that rail, then yes you'll want to confirm and re-zero if needed.
If the optic was only mounted on the upper receiver, then there should be no change from tightening the rail down. |

Quoted:
i zeroed my rifle yesterday. it a 16" psa with a free float rail. i was cleaning it and decided to check the screw tightness of the rail screws with my torque screw driver. i was surprised in that a couple were loose. so i took them out and loctited them and retorqued them . so does this have any affect on zero seeing its free floated? will i need to rezero ? Why were you surprised? You purchased junk from PSA, they sell extremely low quality products when it comes to their AR's and they are full of issues. Doing some research and buying a quality AR would save you the "surprise" of having to deal with PSA garbage while fixing their mistakes. |

If the sight/optic was mounted to that rail then yes. If not, no.

Loose screws will most likely cause poor accuracy or consistency. Just see what you've got on your next range visit and go from there. But, to answer, your question: yes, you may need to. But it also may not matter yet. Check it out and let us know.

PSA sells good stuff as long as it's not PTAC I consider it good, I always check my screws periodically and especially if I it's a pre-assembled upper.
