I know this is a dead thread but a lot of people on here talk about "lining up the dots". The benelli m4 is not aimed in this way. It is aimed by centering the fsp in the rear aperture. The dots look like Micky Mouse head and ears. The darker trijicon are less distracting in daylight because you stop looking at the dots and line up things correctly. At night, Mouse head.

Interesting. It can certainly happen.

The recoil spring tube needs adhesive too, and if benelli can miss the mag, they can miss that. This was my concern about qa/qc.

That is great news in a way, but it also says that QA/QC at Benelli fell down on the job in a big way.

Before you do that go spend a few bucks and buy a 1 pound and then 2 pound weight. Tape each to the end of your barrel. I find a can on longer m4 carbines annoying even with a very forward grip. On the benelli m4 I bet it feels horrible.

No threads on the sbs m4.

I bought 2 of their aimpoint m3 clones. Both broke on m4 carbines very fast. PA replaced both with no hassle or argument. I've heard the T1 is better. I feel the brightness adj. Was the failure

nice That is part of what I love about the Benelli M4 so much. It was engineered so well. I have yet to find a "fatal flaw" to it.

This is typical wear for an M4 carbine cam-pin. Cam-pins in this platform should be changed when they are excessively worn, as they are a contributor to broken bolts (more wear = more slop = more shock) After just 340 rounds:

I'm curious how the cam-pins fare on these in the 10K+ round range. Stranger Danger? Any pictures? I know the cam-pin is an issue on the M4 (carbine) platform, and while I have never heard of it being one on a Benelli, I am just curious about the wear patterns.

Winner winner!

Solid deal!

No stress. I've just very very very rarely seen or read or heard of a true issue with a properly run and fed benelli m4 after the 4 port barrels went away. Some run lighter loads than others, but buckshot not running? So, I follow failures or reported failures I find very closely.

I know, but I told OP exactly how to diagnose and fix the problem because OP posted the topic on a public forum before sending the shotgun to Benelli. I thought OP wanted help/advise and mine was pretty cheap/easy to follow. I've owned half a dozen of these shotguns and have several years experience with them, and offered sound advice as well as anyone could over the internet, in response to OP begging help. OP ignored me and cost themselves a half month or so of wait time, etc. THAT seemed a bit cold to me. No hard feelings toward OP and glad he got his M4 working, but yes, he had to eat crow for one (now two) posts of mine in exchange for asking for help and pointedly ignoring it. Tit tat.

I Told You So I bet it even cycles weak clay loads like ALL of my (about a half dozen) M4's have. Right out of the box my last M4, I fed it 2.75 dram 1-1/8oz Remington STS Light clay loads. It ran like a sewing machine. But, hey, you came back and owned it, props on you! Now go enjoy that wrecking machine!

Reliability should be Improved with low recoil ammo. Weight on the muzzle...recoil reduced. Should worth with any ammo if It works with shot. I have friends in cali who have class 3 stuff... Muzzle signature varies from around high 130s to high 140s depending on baffle stack used. Ever handle a Teague choke tube? Not all chokes are as thin as you are used to. Teague is down right beefy. I'm sure this is too. More room than you think in that area of the barrel. Most tubes taper. This one night not. Cleaning? You have never shot suppressed, I see...oinkoink!

Threads should be fine. My prediction is that a 32 oz at worst and 18 oz at best weight makes people hate how and shotgun handles when it's balanced 100% in its entirety past the end of the barrel. I say the threads will be find because m4 rifles with comps and cans and blank firing adapters are fine and threads are threads. Similar barrel material and larger threads on the m4 shotgun to boot.

The weight kills it. Totally awesome on youtube but in hand I bet It's annoying.

Why? I understand the Kalash deal, but how does this affect Benelli? I highly doubt Benelli will get the same treatment. a) They are not a based in a country with strained US relations. b) Lots of them are sold in the US to LE agencies (LAPD bought M4's, as did others, as does out military, and MANY bought M1's, etc. and still need parts for them).

Imo Gdi is more for a precision rig where weight is much less important.

I want to say a decade or longer. Only in the last few years have they gone mainstream. Andrew Bobro is a class act and his mounts are the best machined I have seen out of adm, larue, and Arms. Gdi might compare but I have not handled their products.

The Geissele hammer is the only part in this list that hasn't given owners grief (aside from the magazine tubes/followers). I've had issues with FFT's FCG (It disabled my M4), and plenty of people have complained about the FFT handguards, of varying levels of severity of fitment issues.

Word is, this fall.

Love Bobro, but the ADM mounts are slimmer, I think. Bobro is hands down my choice for other things, though.

THen I found this, and tried to translate part of it, and found something else interesting: http://www.benelli.it/sites/default/files/contenuti/press/pdf_file/M4%20-%20Diana%20Armi%20-%20Maggio%201999.pdf Lo m4 supera largamente tutti i requisita del programma JSCS e per quanto riguarda durata ed affidibilita i valori sono di 25,000 colpi senza sostituzione di parti (sparando cartucce da 70mm) intervallo medio di 677 colpi di fra gli inceppamenti e di 2,000 colpi fra i guasti e questi valori sono stati rilevati in false di messa a punto dell arma. Con la certezza quindi di vederli ancora migliorati negli esemplari di serie. E al proposito, come non ricorder i test tanto l'intervallo medio fra gli inceppamenti sona stata di 1,500 colpi Translation: The m4 greatly exceeds all requisitioned program JSCS and as far as durability and reliability for the values ​​are 25,000 shots without replacement (shooting 70mm cartridges) average interval of 677 shots between jams and 2,000 rounds between failures and these values ​​were calculated using false setup of the weapon. With the certainty of seeing them again and then improved in the specimens of series. And in this regard, as will remember the test so the average interval between jams person was 1,500 shots.
