Gabriel91 Posted April 15 Share Posted April 15 Hey guys! I’m new to the M4 familly and i have a quick question. Is it normal to see that kind of wear on the bolt carrier? I’ve never seen any other M4 like this. It rubs against the part of the barrel that goes into the receiver. I don’t feel anything when passing my nail on any of these wearing spots so i think it’s only finish that wears off. I have to say that i love the gun and it works really good. I’ve shot around 400 rounds of target loads and another 100 of buckshot without any malfunction. I’m curious because it’s my first gun and i don’t know much in the subject. Thank you in advance!

Gabriel91 Posted April 15 Author Share Posted April 15 in fact i think it’s the chrome that is chipping of the part of the barrel that goes in the receiver… Quote Link to comment Share on other sites More sharing options...

I’m new to guns and it’s also a first for me to spend that much money on something like this. I’ll learn to see wear forming on it through the years of use.

REZARF2 Posted April 16 Share Posted April 16 If it ain’t broke… seriously though if it’s running well for 500 rounds so far I wouldn’t be concerned. If the finish is wearing off in spots and you start to see corrosion then I would come back to this. I’m sure Benelli would make it right. in the end these are tools. Even if they are beautiful Italian tools and they are going to take some hits as you use them for their intended purpose. It’s hard to tell from the pics and lighting but is the finish wear on the bolt down to bare metal? 1 Quote Link to comment Share on other sites More sharing options...

It’s hard to tell from the pics and lighting but is the finish wear on the bolt down to bare metal? yes it’s to bare metal. But it’s only the cerakoted finish that wears. The metal is not scratched at all. I’ll keep it oiled and maybe after it has break in correctly i’ll send it getting milled and dlc coated. The "cheaper" finish will be a thing from the past. Thanks for the answer! Quote Link to comment Share on other sites More sharing options...
RxArms Posted April 16 Share Posted April 16 Okay I didn’t notice the bolt wear, that imo is not normal. and your bolt is Cerekote? The M4 bolt is fairly loose and not tight enough to notice less than 1 thou of paint i don’t think…. something may be out of spec there with the wear on your bolt 1 Quote Link to comment Share on other sites More sharing options...

Apparently wear is normal on moving parts(from benelli). They told me to make sure everything is assembled correctly and that if everything works correctly then it’s ok. Maybe the finish on the bolt is cheaper on the newer models than it used to be in the past. The finish wears off at the same place of yours on your picture so i guess it really is a cheaper finish on the carrier Quote Link to comment Share on other sites More sharing options...

Here’s 2 bolts that I’ve used a ton, no where on them at all. 1 Quote Link to comment Share on other sites More sharing options...

I bought it new on the secondary and it sucks because from what i’ve read, the warranty is only for the first owner…. I’m pretty bumped about my first gun…. Was going with the best to not have problems and here i am!!! Sweeeeettttt Quote Link to comment Share on other sites More sharing options...

Feel free to pass along photos of my bolts showing no wear, I have thousands of rounds through these. stoeger doesn’t have any idea what they are talking about you will have to be a bit insistent. try and get receipt of purchase from the guy u bought it from?

It rubs against that chrome lined part of the barrel. I can’t feel anything when touching it. It’s only visually. It really bugs me seeing that on a 2k gun when even cheap truknelli are ok lol. The gun eat everything tho, nothing to complain on that side Quote Link to comment Share on other sites More sharing options...
RxArms Posted April 17 Share Posted April 17 (edited) I’ll have to investigate my guns more, maybe some others can chime in. Edited April 17 by RxArms 1 Quote Link to comment Share on other sites More sharing options...

RxArms Posted April 17 Share Posted April 17 I would take your trigger group out, put the bolt in and see if it is something further back in the reciever. I am not 100% convinced it is the barrel. 1 Quote Link to comment Share on other sites More sharing options...
REZARF2 Posted April 17 Share Posted April 17 Man I don’t think you should have contact there. If open it up, air hose it all, hit everything with brake clean and spray it with a light lube, then darken the area with some sharpie and see if you’re still rubbing. I’d press Benelli, that’s not normal. 1 Quote Link to comment Share on other sites More sharing options...

I putted sharpie on it to see where it rubs and it’s exactly at the same place as the first picture you showed me where yours wears too. I think it’s mostly a cosmetic issue because there’s no digging in the metal at all and the gun shoots A1 everything i put in it. If benelli won’t do anything because i’m not the original owner(which would suck for a gun that price) i think i’ll just shoot it a ton and send the bolt carrier to get custom milled and dlc coated.

I’m not the original owner(bought it new on the secondary)so they may not warranty it… at least it functions really well and it’s not deep scratches in the metal. It’s really only the finish. Which still sucks… Quote Link to comment Share on other sites More sharing options...

Have you checked the receiver? There is a ledge right behind where the barrel seats, and it could have a burr on it. There’s other reasons it could wear other than on that spot on the barrel assembly. I also think the wear you see there on the barrel assembly could be from the bolt head and not the bolt carrier. (As all M4 will wear there on the barrel assembly). i also think it is possible your bolt carrier is not in spec. Reason being is I see wear on the back, and wear on the front but not in the middle.

I also putted a straight edge right on the wear with a light behind to see if the bolt is uneven and i can’t see anything. My guess is that maybe there’s too much chrome on that ledge. At least i’m happy it works really well Quote Link to comment Share on other sites More sharing options...
