forzArmata Posted January 26, 2013 Share Posted January 26, 2013 Wtf is going on here? It seems that my aluminum receiver is mashing under the force of the shells being ejected(?), from the looks of things. My Benelli is new with under 200 rounds through it. The bolt is cycling as smooth as silk, and there is no evidence of rubbing in any way. Here's a pic - you can see the aluminum folding over in the direction the shells get ejected. It's fairly minor now, but I can catch the lip easily with my fingernail. And if it's this mashed already, I hate to see it after 1000+ rounds.

John P. Posted January 26, 2013 Share Posted January 26, 2013 I think it's ridiculous, too, but that's "normal." Quote Link to comment Share on other sites More sharing options...
StrangerDanger Posted January 26, 2013 Share Posted January 26, 2013 Completely normal. I'd say hit it with Alumablack once in a while if it bugs you. After 13k rounds, mine is almost beveled. Quote Link to comment Share on other sites More sharing options...
forzArmata Posted January 26, 2013 Author Share Posted January 26, 2013 Completely normal. If it was black, I'd say hit it with Alumablack once in a while if it bugs you. After 13k rounds, mine is almost beveled. Could you post a quick pic? Quote Link to comment Share on other sites More sharing options...
StrangerDanger Posted January 26, 2013 Share Posted January 26, 2013 (edited) Best I have right now. I'm not at home. The top edge is worn, and the rear bottom has a groove from the rim of the shells. Edited January 26, 2013 by StrangerDanger Quote Link to comment Share on other sites More sharing options...
forzArmata Posted January 26, 2013 Author Share Posted January 26, 2013 That's great, thanks SD. I have an idea...I could get my gunsmith to bevel that entire edge and re-black it so it looks mint. Better to take care of it now than later when it's all mashed. Thoughts? Quote Link to comment Share on other sites More sharing options...
StrangerDanger Posted January 26, 2013 Share Posted January 26, 2013 Trouble is, the anodizing gets scraped off by the shells. So even if you refinish it, it'll keep wearing down. Even a fancier teflon based coating would wear down eventually. I'd just get a bottle of Alumablack, and hit it whenever it bothers you.

XTrooper Posted January 27, 2013 Share Posted January 27, 2013 Are there any scratches on the head of your hammer? A firearm, including your M4, is a TOOL! They get scratched and otherwise marred in normal use. If someone wants their firearm to remain in pristine condition, best leave it in the safe and never load or fire it.

truckcop Posted January 27, 2013 Share Posted January 27, 2013 Y'a know, I had those nearly exact same words down and then cancelled because the last time I made a comment like that I got jumped all over. For the record, +1. Quote Link to comment Share on other sites More sharing options...
forzArmata Posted January 27, 2013 Author Share Posted January 27, 2013 Are there any scratches on the head of your hammer? Yes, but what's your point? The hammer is one thing, the finished aluminum receiver is another. A firearm, including your M4, is a TOOL! They get scratched and otherwise marred in normal use. If someone wants their firearm to remain in pristine condition, best leave it in the safe and never load or fire it Thank you for your insight. I believe you are missing my point here.. so let me make it clear one more time. My BRAND NEW Benelli M4 with UNDER 200 shells through it is DAMAGED. Like I said, I can understand wear and tear after a thousand or more rounds, but to have noticeable damage like that after realistically 150+ rounds is just odd. That's my issue. Wear is not a problem as I use my gear and run it hard. I do have a problem however with a $2100 CAD shotgun that is damaged from spent shells (plastic and brass) after one or two shooting sessions.

XTrooper Posted January 27, 2013 Share Posted January 27, 2013 The ejection ports of LOTS of semi-automatic and automatic weapons get scratched and dinged after the FIRST cartridge or shell case is ejected. That's a fact. Your M4 is not "damaged" and the fact that you believe it is demonstrates a gross lack of experience and understanding of these weapons. I can guarantee that if you checked every M4 on the planet that has been fired at least a dozen times, you'd find at least as many scratches on every single one of them as yours has. Still think it's damaged? Send it back to Benelli for "repair" and see what happens. If nothing else, it should make for some interesting conversation amongst their gunsmiths. Best of luck to you.

Unobtanium Posted January 27, 2013 Share Posted January 27, 2013 100% normal, just like cam-pin wear in an M4/AR upper. Don't look at it. Quote Link to comment Share on other sites More sharing options...

It is not damaged, and this falls under the category of wear. If you don't like it, sell it and don't ever buy another M4 shotgun, because I can promise you 100% that it will do it, too. I doubt you meet anyone near as OCD as me about their gear, either, so take it FWIW. Quote Link to comment Share on other sites More sharing options...
forzArmata Posted January 27, 2013 Author Share Posted January 27, 2013 Got it, thanks for the replies! I just never noticed this stuff on my previous M4. I guess I'm just paranoid because I'm noticing all these dings and damage (bolt, receiver) after one quick session firing a handful of rounds.

It's normal wear and tear within tolerance. Don't stress over it. Only stress over things that should NOT be there. Other stuff for you to look at that will drive you crazy... The barrier battering the back/inside of your receiver. The hammer-face being peened and polished. The linkage being scarred as it rotates in the base of the carrier during recoil.

jaegerbataillon511 Posted January 29, 2013 Share Posted January 29, 2013 I would love to see that Benelli make their M4 receivers from steel. So much wear and tear problems would be solved and I doubt it would gain so much weight to the firearm. Quote Link to comment Share on other sites More sharing options...

When you find me a Benelli 7075 alloy receiver that has "worn out", please post a picture of it. Quote Link to comment Share on other sites More sharing options...

jaegerbataillon511 Posted January 29, 2013 Share Posted January 29, 2013 I know that a M4 alloy receiver will last much past 20000 rounds, but from a cosmetic view it is prone to get scratches and small deformations during normal or combat use.
