New 500 Barrel Fit Issue

[DKeat]

Hi there, new to the forum just bought a new 500, and wondering if it’s normal to have a 0.03” gap between the barrel and mag tube? Same gap is between the barrel rail and receiver rail.
Barrel is flush inside receiver (no gap in there).

Welcome. Nothing to worry about. As long as the barrel screw is tight your good to go.
I have a small gap in my old 500 also about the same as your pic.

Thanks!
There is also very slight (maybe 0.01”) play when trying to hand rotate the barrel with the screw tight, and hadn’t seen gaps like this before so wanted to be sure I didn’t need to send for warranty before I put any rounds through it

Welcome to the forum from the socialist republic of New York State.
As far as your new Mossy 500 goes you should be good to go. Make sure you have disassembled, inspected and cleaned the firearm. Also apply some decent gun lubricant to the moving parts. Upon reassembly make sure to hand tighten the barrel retention screw and you’re good to go. It’s a “ loose fitting system” by design. The really important areas of fit and function are inherent to the shotgun. That’s how it retains the durability and reliability under adverse conditions.
Shoot it a bunch and report back.
