Gouges on ceiling of Maverick 88 receiver?

[Rossiter93]

Hello all. I was just sitting down to diagnose some rough cycling of my maverick 88 that just recently started, and when I stripped it I noticed two gouges in the ceiling of the receiver that are new since the last time I had it apart. They are quite rough to the touch and I suspect this is what is causing my rough cycling. I can smooth them out myself, I'm just wondering if anyone has had this happen on their shotgun before or if anyone has any idea as to what may have caused it in the first place. It started in the middle of a skeet session with my family, and was being fed Winchester 100 count value packs or the federal equivalent, so nothing crazy or exotic. Thanks in advance!

Ive had a bunch of these over the years, and here are my findings.......some are slick as glass & some feel like some one dumped in a hand full of sand .LOL They are a budget shotgun,..some are good, some not so good. Its very normal.

Happened to mine as well, dont know why or how like you I was just using basic shot in it. Polished it down and it never got any worse.

I did some research on this. Mossberg service centre calls the marks normal. It is do to sharp edges and burrs left on the bolt after machining. You can smooth them down and de burr the edges of the bolt or you can keep shooting it until the wear stops. It seems that the wear stops very soon after initial use. I have a 50 year old model 500 Mossberg that has no marks but finish wear inside. Likely do to the fact Mossberg spent more time de burring bolts in the old days. In any event the marks are normal and the gun will smooth up with use.

I'd deburr what need's deburring, polish what need's polishing oil it well and use it

Or do a bunch of cycling while watching Golden Girls reruns.

I noticed a few burrs and super sharp corners on my bolt from an old lakefield 500. After noticing said gouges on the receiver. Had to take a file to the bolt in a few places. Feels a bit smoother now.
So i guess the problem has been around for a while.

I'll have to check the bolt again when I get home. I didn't notice any sharp edges on the bolt when I had it stripped down the other day but I'll give it a second look.
Thanks fellas!
