I wouldn’t worry about it too much. High spots and hard edges get knocked off with use. Since they’re magnetic, they obviously aren’t aluminum from the receiver or lead Deposits that were scraped out of the barrel. It’s likely from the area where the tail of the bolt goes into the receiver extension. Clean them out, shoot the piss out of it and see if more return.

Good deal. I already placed the order. Interesting about the UV burn.

I think Nordic makes that +1 mag extension. Briley makes a similar unit now too. I’ve seen similar handstops from Strike Industries.

I knock mine most of the way out with a Starrett punch while pressing the button in slightly. The punch isn’t quite long enough to knock it all the way out. So I then use a set of transfer punches. The larger diameter Starrett punches will last a lifetime. The smaller ones are consider consumable and are easily destroyed. Particularly 3/32 and 1/8 punches.

Talked myself into it and ordered one up for the H2O.

I’m not a huge fan of the Cerakote models. They seem to have been done a little sloppy. The Cerakote doesn’t provide much benefit over the standard finish. What it comes down to is if you like the look.

I’d get a pin that is smaller diameter than the button spring. Then cut it to length so the button cannot be depressed with the pin inside the spring. I’d leave just a small amount of play so you can depress the button slightly when tapping the retaining pin in place. This would be a lot easier than drilling a hole thru that steel button, then tapping it for a screw. The only way to get the hole drilled properly would be to indicate it in a lathe. Preferably on a 4 jaw Chuck. Trying to punch out the hole with a drill press is likely going to be off.

Every Benelli I have ever used has that wear pattern on the ejection port. If it bugs you, rubbing some Alumablack on the bare aluminum will blacken it until you fire it again.

Good job! I’m trying to convince myself to spend the money and buy one of those Briley carbon fiber magazine tubes. I think that will look awesome on my H2O build. Plus cut a little more weight off the front.

You’ll use both frequently after you buy them. Definitely won’t be a one and done thing.

A stripped one? I probably have a few.

Look at buying a MAPP torch. I bought mine at Home Depot. They’re cheap and pretty safe. They deliver a lot more heat quickly than a heat gun. It’s no acetylene torch, so you don’t have to worry about melting metal. The faster you heat the magazine tube, the less heat will wick into the receiver. It has an igniter in the trigger so it’s easy to ignite and shut off. No mixture knobs to mess with or anything. If you can operate a BBQ igniter, you can operate this torch. Apply the heat to the base of the steel magazine tube and rotate it around the tube evenly. Apply heat for 20 seconds, try to unscrew the tube. Apply more as needed. https://www.homedepot.com/p/Bernzomatic-BZ8250HTKC-MAP-Pro-Hose-Torch-Kit-BZ8250KC/203391035 Same one I have. After 6 years or so, I’m still using the same bottle. Getting a vise is a good idea. Get some padded jaws to avoid marring your work. Check where you’re clamping carefully. You don’t want things like the trigger pin under the clamping area.

There is a black one listed on gunbroker. https://www.gunbroker.com/a/my-gunbroker/sell/selling?TimeFrame=17&Filter=0 Im thinking about giving one of the carbon fiber magazine tubes a try. They’re 3.4 ounces. Carriercomps come in at 5.5 ounces.

Seems once that was submitted, the item showed up. I played with the device tonight a little on the burnt bronze M4. I'm going to try to get out and test it in the next day or so. Right now I am leaning towards the idea that the device will cause malfunctions. The device retards the rearward movement of the bolt carrier. This can complicate the cyclic action of the bolt carrier. My main concern is it seems to limit the rearward travel slightly. If the carrier doesn't travel far enough to the rear, the lifter won't cycle a round up to the chamber.

Correct. When you look down the barrel of the current production M4, you will see two ports. One port for each ARGO plug. On the 4 port models, each ARGO plug had two ports about half an inch from each other. I haven’t seen one of these 4 port barrels in years. My burnt bronze M4 came with one when I bought it in 2004. It was the first release of the 11703 models with the neutered receiver extension. Within the first outing, I snapped a piston in half firing 2 3/4 buckshot. Took Benelli a month or more to send me a new piston after mailing them the broken one. Then for another 7000 rounds, the shotgun performed okay until I noticed that the bolt carrier was getting stuck when pulled to the rear of the receiver. Closer inspection found that the face of the bolt carrier was mushroomed where the pistons make contact. The carrier was so badly deformed that it was binding inside the receiver. The 4 port barrel was battering the carrier to death. Trip back to Benelli at this point at my expense. Benelli replaced the entire bolt carrier group, barrel assembly, pistons, ARGO plugs, and handguards with 11707 model parts. Now at 17,000 rounds, no more issues have been encountered.

The 11707 forward had the larger seat ring on the barrel and the modifications to the hook shaped area at the rear part of the barrel extension. Many of the Benelli sales photos showed the trigger guard and even the collapsible stock bodies, top rail Np3 plated. They either back peddled upon release or they had just photoshopped them. The only M4’s with plated trigger packs are ones people have had done themselves. They either did this as a cost savings issue or they determined the oem trigger frames were riddled with pits in the aluminum casting which show up better when NP3 plated.

Glad to help!

Only way I’d trust Armslist is face to face in a safe place like a police station parking lot or at a gunshop to act as the middleman. Or maybe with someone good providing over watch.

Disputing my charges to PayPal for the sale. Tired of waiting on this retarded seller to get his crap together. F left on gunbroker for dicking me around for two months.

Good info. I think when Benelli got their peepee slapped by the ATF, they took what was left of the 11711 batch and returned them to 922(r) compliance. Benelli was attempting to state that the refinishing process was manufacturing the firearm here in the US which would exempt it from 922(R) compliance. The ATF disagreed.

Noted mistake on my list and I can’t edit the post for some reason. “I will note that 60 were released from Benelli with 7 round magazines and functional collapsible stocks until the ATF made them stop.” This should be under the 11711 model. Not the 11707. Sorry.

They won’t have a titanium NP3 since they won’t apply that finish to the titanium. A good Cerakote guy could probably paint a titanium to match your Cerakote finished M4 though. I could give you the names of a few shops if interested.

Correct, it is the Cerakote model. The 11795. I would order a muted finished magazine tube from carriercomp. The finish matches fairly close to the titanium finish. It won’t be perfect, but you’ll be the only one to notice. You definitely want to go titanium to cut weight. The bad news is carriercomp orders currently are looking at November deliver times.

M1014/11701: Limited edition flag model. Comes with a oem collapsible stock that doesn’t function. The receiver extension is neutered to prevent function. Barrel does not have removable chokes. The original release of 1-2500 came with aluminum trigger frames. Current production flag editions outside of this initial release have polymer frames. Original release had a different barrel design that didn’t have the seating ring that mates against the receiver face. Handguards were slightly different as to account for this seat ring. 922(r) rules apply for modifying the shotgun’s capacity and collapsible stock. 11703: When originally released, this was a 4 port barreled model made for low recoil rounds. Everyone hated it and Benelli would replace the barrel if asked. The shotgun would beat itself to death if standard rounds were used. It also came with the neutered receiver extension. It came with a pistol grip stock. Barrel assembly has removable chokes. Came with an aluminum trigger frame. For some stupid reason, Benelli released this model number again around 2014 with some changes. The barrel is the standard 2 port barrel. It has a regular 3 position receiver extension. It came with a polymer trigger frame. Came with a field stock. Why they didn’t give it its own model number, we will never know. These models are rare to see anymore. 922(r) rules apply for modifying the shotgun’s capacity and collapsible stock. 11707: This is the gold standard model. Comes with a 3 position receiver extension. Barrel is a 2 port barrel with removable chokes. The barrel have the new seat ring design and some modifications to the barrel extension inside the receiver. Early production models came with aluminum trigger frames where as current production models have the polymer ones. We’ve seen some minor changes in finishes on small parts like the Argo plugs and receiver anodizing over the years. Some Receivers almost have an OD green hue. These models come with a 5 round magazine that has a limiter in place. 922(r) rules apply for modifying the shotgun’s capacity and collapsible stock. I will note that 60 were released from Benelli with 7 round magazines and functional collapsible stocks until the ATF made them stop. 11710: This M4 essentially the same as a 11707, but it comes with a field stock. 11711: This model has all of the features of the 11707, but the shotgun was plated in Np3 by Robar. These are quite rare and not to be confused with the Cerakote model that is painted silver to copy the look. These true NP3 plated models are arguably considered the best model due to the performance of the Np3 finish. 922(r) rules apply for modifying the shotgun’s capacity and collapsible stock. 11713: This M4 is a law enforcement model that is 922(R) exempt like the 11721. This model has all of the features of the 11707. The only real difference is it comes with a steel 7 round magazine tube. 11717: This model has all of the features of the 11707, but the shotgun has a three tone desert camo pattern. 922(r) rules apply for modifying the shotgun’s capacity and collapsible stock. 11721: This is a law enforcement model that has all the features of the 11707 but doesn’t have to abide by 922(R) restrictions. It isn’t meant to be sold to civilians, but they often are. They are sold at a premium price. Given that it comes with a collapsible stock, this makes the price more appealing. The shotgun includes a 7 round steel magazine tube. 11723: This is a 14” Entry gun version of the M4 the barrel doesn’t have a removable choke. This would be a NFA firearm. It comes with the field stock. Other features are similar to the 11707/11721. 5 round capacity due to length. 11724: This is a 14” Entry gun version of the M4 the barrel doesn’t have a removable choke. This would be a NFA firearm. It comes with the oem collapsible stock other features are similar to the 11707/11721. 5 round capacity due to length. 11795: This model is similar to the 11707 in features. The only real difference is it is Cerakoted. I have seen both a H2O titanium finish and a dark earth color option. Pistol grip and field stocks can be had under this model. 11796: This is a law enforcement model like the 11713/11724. The only difference is the Cerakote paint options. The firearm is generally sold with the oem collapsible stock and a 7 round magazine tube. There may be other options and models out there. Benelli has a European model with a slightly longer barrel. There is also a redesigned M4A1 that has been floated that uses the Supernova collapsible stock and has a railed handguard assembly from the factory. I don’t think these options have been imported to America yet.

The model shown is a Cerakote model H2O. You can tell by the black bolt carrier. A true H2O was NP3 plated by Robar back in the day. These aren’t made anymore and Robar is now out of business. Other places can have the NP3 finish applied, but you’ll have to do it yourself. the easiest way to tell which model it is is by looking at the bolt carrier or the receiver extension. The NP3 models will be plated silver on both those parts. The Cerakote model is simply out to copy the look of a true H2O.
