Benelli would do well to apppoint a regular member with reputation to have low level admin power, honestly. What a crap shoot.
a velocity filter would be useful, stopping members/IP from doing more than 2 new posts an hour or something.

All, i wanted to just follow up on my results here for posterity on the off chance that google brings some other lost soul to this thread in the future.
I was able to buy an M21x1 tap and with it I was able to “restore” sufficient thread for a good solid fit. I did slather it up with loctite and i let it cure for 24 hours. I ran a few shots thru it (in a vice at an outdoor range pulling the trigger with string for safety) and can say with reasonable confidence that it’s pretty solid.
I will be using the gun very carefully for the next few weeks putting a lot of rounds thru it and checking / re-confirming a very tight and strong fit of the tube in the body of the gun.
Thank you all again for the wisdom - I will continue to proceed with caution, but I’m thrilled to have my M4 back together as our Italian overlords intended.
I think the worst that can happen is a round will fire, bolt goes back, recoil tube dislodges, your buttstock comes off with a bit of force. I don’t think there is any real danger other than that, the bolt can’t exit the rear of the receiver it will just impact the back of the receiver and will be contained.
if this were to occur I think you’d have warning signs, such as a slightly loose recoil tube before it happens.
I’m glad you got it sorted out! Sounds like it will work just fine as you felt the torque of the nut was sufficient.

Wow thanks for posting, I don’t take down the bolt at all if everything is working well, but I might start cleaning it more often once a year as you say.
-
Movement is normal, the sound looks to me like the buttstock pin is compressing a bit, then releasing when it seats back into the groove, causing that sound. I don’t believe it is out of spec, but maybe some others can chime in regarding the sound.

Just a thought on the M4 buttstock for those that feel it is sub par.. I’ve seen a lot of collapsible stocks, and I can’t recall any that come close to the quality of the M4 legacy buttstock. Not often do you see an aluminum frame collapsible buttstock, everything these days is made out of polymer. It is one of a kind imo, and this is why it is so expensive, I haven’t seen any clones but I doubt clones have aluminum buttstocks.

I’ve never done a BF sale, but maybe this year, I’m kinda a one man shop and fairly small. But it’s on my mind this year so ya never know!

The recoil tube/buttstock is very tight tolerances. I’m lucky to have a very tight buttstock for fitment purposes on my 6 pos checks. While a few other of my buttstocks fitment is looser. So imo it is more to do with the buttstock than the tube.
-
Yes I would consider using a tap to try and clean up the threads, make sure you use oil.
as long as the recoil tube will thread in and be secure, you can load it with a ton of red loctite when you do the install, and it should be okay. But it does need to hold torque, so you’ll have to be the judge of that.
the receiver is threaded M21x1, but feel free to confirm with Benelli first. Further, I would find a local gunsmith to do this imo.
also I don’t see how Benelli can fix the threads, other than using a tap like you may do. They may just say you need a new receiver instead of attempting to service it at all.
I am curious how this happened, Did you force a cross threaded tube in the whole way? Did you over torque and is the threads stripped?

I’ve already let the cat out of the bag with the mlok heatshield I’m releasing.
unfortunately I’ve hit some snags that showed up after 1K rounds, needing to redesign it a little. At this rate I might have the beretta 1301 heatshield out before the M4.

Might I suggest changing the extractor, is cheap enough to see if it works?

changing the spring and pin also might be worth it.
-
I would service the extractor. It is not normal to have the bolt back like that and a shell half way extracted.
do you have any friends with an M4? If so, pop their bolt into your gun and see if it functions properly, if so, then you know it’s something off with your bolt assembly and most likely the extractor.

I just checked the ATF website, and looked at your website and while I agree I don't know about importing the italian part to the US, the form 6 exemption on the ATF website is pretty clear that sporting shotgun parts are exempt from having to file a form 6 to import the part. Honestly, just looking at all this has given me a headache and I commend you on the research you did and your ability to offer parts to US customers. It's absolutely insane to me that we have these rules... but what do I know, I'm just a civilian lol
I would follow what I do on my product pages, use the same customs code and customs description. Yes it was quite time consuming to look through all the handbooks and ATF laws, but it all made sense in the end. And it helped me know the laws and rules for shipping my items to USA without issues.

So I just found one on a forum and the stock is from Canada.. would that be legal to buy and have shipped from there to me in the US? I looked it up and there's a ton of different answers on reddit and other forums.
I don’t know, it is made in Italy. I’ve never tried to send something made in Italy to the USA.

If you are concerned, take some sandpaper and smooth out the burrs created by the ding (if there are any).
i have multiple dings on my bolt carrier rails from cleaning and whatever else, these things are going to happen. If I feel a ding should be smoothed out I usually take some coarse sandpaper to it.

Appreciate the info as well as the rapid response! Look forward to doing buainess with you.
Thanks! I forgot to mention, I use hardened 4140 ordnance steel. I don’t know what grade 4140 briley uses (it is not listed)
-
Our tube notches are heat treated to prevent deformation. Which does make a difference, Also a custom PVD surface finish. Aside from those technical benefits. It is $120 cheaper 😕
no issues at all shipping to USA, been doing it for years. Shipped thousands of packages down there by now.

No. It’s that most Canadian dealers don’t want to mess with the import BS.
Ya I think so, I’d have to look into Italian made parts importing into USA. All my items are Canadian made and have certain exemption status with the USA. I don’t think it’s the same for countries outside of North America.

The detents on the Benelli M4 are not completely consistent. Which can cause problems at times, which does not happen often in my experience. Unfortunately this is how the Benelli m4 is. Kind of hit and miss, (Much more hit than miss).
-
That is awesome, thanks for sharing!
-
Fun fact, in Canada I got one from a dealer brand new for CA$330, or US$240.
the USA dealers are price gouging bad on these.

I’ve had to redesign the heatshield unfortunately. Problems started to occur after 1K rounds and had to go back to the drawing board after a few months of trying to remedy it.
Hoping to have a whole new prototype for testing in January Feb.
