The Benelli M4 is a fantastic weapon system produced by Italian firearms manufacturer Benelli. It was developed for a USA semi auto shotgun request for the military. The Benelli M4 is now one of the most commonly used shotguns in Military and Law Enforcement. This was the first gas operated shotgun Benelli designed, having traditionally used an inertia driven system in the semi automatics. The Auto Regulating Gas Operating, or ARGO for short, is a self adjusting, self cleaning system that allows both light field loads and heavy buckshot/slugs to be used and reliably run interchangeably without any adjustments to the shotguns gas system.
Best Benelli M4 Clone ever made ( Turknelli )
Ideal for Home Defense and Tactical Shooting

Thank you, I purchased a 5 position tube. Also works for the field/fixed stock models. The quality on these is honestly great and it does come preassembled with buffer, spring, etc.

[@Drax-qr2xb]

The amount of effort needed to take this tube off is freaking ridiculous

[@gregscheikofsky5606]

While you have it apart, it would be worthwhile to remove the screws from the rear site assy and the optics mount and clean and re-threadlock them with a QUALITY thread locking compound and reinstall them. I had all the factory screws come loose on these components while I was doing successive rounds during a break-in procedure. The receiver got hot and the factory threadlocking compound gave way. I will say the gun handles most any loads I've put through it. For the money, this is pretty good gun, however I have had some issues with the Panzer adjustable stock coming out of position during firing. I believe Panzer would warranty it, and I'll have to check into it. I have put approximately 500 rounds through it so far.

[@artilleryguy0252]

The Panzer M4 works flawlessly and I'm satisfied with it. I was excited about upgrading the stock. Took it to the range and the stock would collapse with ease. After 100 rounds through the firearm I could not get the stock to collapse. After disassembling the firearm I had to force the stock to move and it had grinding. After finally getting it off I could see scrapes on my buffer tube. I cleaned the inside of the stock tube and even tried lubricating it. Still harder to move than it was and it is wobbling when it finally gets into position. I like the company and own the EG 200 and M4 with satisfaction. I wouldn't get this product until they work out the problems because I'm stuck with a faulty add on now.

Just purchased this the one thing left off that might help is the nut that holds the pistol grip on has to be put in the grip a certain way to lock in. Mine came with the new buffer tube as well

[@brandondavis4306]

what way does it have it go I bought one today and it came with the collapsible stock from buds for free and I can't get the pistol grip to go on so any tips would be a major help thank you.

[@brandonpayne5000]

​@Brandon Davis the new grip should of come with another nut. That goes into the back of the new pistol grip. Then just spin it on. I had to take it off a few time cause the nut has to go on a certain way but there's not indicator which is correct

I have to revise a comment YES the stock kit (Two Part, without buffer 5 position buffer tube soea indeed come with a locking button) hope I did not offend Mr Mustache. Now for the install. just showed up at my door. thanks for an affordable alternative to the overpriced ones the other guys sell. now on to finding a magazine extention that does not need to be filed ro fit.

[@thornie123]

FYI to anyone with a Charles Daly 601 DPS you have to take the ol dremel tool to the pistol grip to be able to get the fire control group in and lined up with the pin. Other than that great stock for the price.

[@jasperg35]

[@jasongarcia8003]

Seems mine won’t come apart as easily as his from new never fired condition. After about 20 mins I gave up trying to take out the charging handle and just took out the trigger by popping the pin out. Also that nut seems to be put in by Thor. Even with a heat gun I needed a vise to hold the gun and put a wrench on it.

[@panzerarmsusa]

Can you pls send email to [e-mail]

[@matunutz1229]

this guy doesn’t really show the direction of the wat the tube supposed to be set 👎

[@laqutis1119]

It's a absolutely pain in the ass, in order to adjust you must turn the tube to the right and get it on the flat part, then back left to lock. So, once it's in a position that's locked and won't go up and down, tighten it until the end of the tube is flush with the inside. The tighten locknut and insure it's straight by wiggling it back and forth to find the exact middle point.

[@beesting5693]

Can somebody explain it taking the barrel off was truly necessary? Seems to me on you need to do is take the bcg and firing assembly out

[@austingoodson]

After installing the adjustable stock, how do you remove the adjustable stock? I cannot get the adjustable stock off the buffer tube.

[@danielritchey3146]

Did you find out how to remove the stock from the buffer tube? I’m having the same issue.

[@austingoodson]

@@danielritchey3146 yes I did…it’s aggravating but I finally got it off. If I remember correctly, extend the adjustable stock about half way down then find the notch that allows you to turn the stock counterclockwise (gun positioned the same way you would shoot the gun).

[@TheMike278]

Anyone else's adjustable stock only lock all the way in or all the way out ??? WTH..I have the 5 notch tube not the 3. I couldn't get that lock nut off with all the heat either. I made it home together but wonder if that my problem?? Anyone ??? Help.

[@Nerdy_Vet]

You saved my ass, I was getting frustrated @@austingoodson

[@willgriff9559]

About a third of the way to half the way down the tube there are 2 lines. The first line is the marker for the middle of the 3 stock length adjustments. The second line is for stock removal. Line the edge of the stock on that line. Rotate is counter clockwise and pull out. It was sticking for me till the finish wore off enough to allow it to come off easier.

[@killerjack111]

Do the new Panzer Arms M4 not come with a three position stock tube. I just got mine and it didn’t come with it, I even got the stock and grip to put on. So now I’m disappointed.

[@davidm4339]

I got mine a few weeks ago from Bud's gun shop and it came with the fixed stock. I was pretty disappointed. I thought they were shipping with the newer, collapsible ones.

The newer Models have the notches already and you don't need another buffer tube. Only with the earlier models you will need to swap it out. With the newer models you can just swap out the stock.

[@SOSdoorgunner69]

Why does my barrel assembly not go back together as easy as yours Mr. Mustache? there's a pad part of lower receiver that the chamber can't get by. have to kind of pry carefully and with luck it gets by, then have to push down muzzle first on carpet and get it to seat all the way into receiver. once it's together it's an awesome shooter, Winchester Sabot slugs shoot like a rifle. Federal Tactical HI power 00 buck stay inside 8" at 25 yards. no FTF no FTE. just always scared to pull barrel assembly off to clean, as it's always a pain to get that assembly slid on as easy as yours. Amd when will you answer the question about where can we get the mag ext. and bolt handles etc etc. I mean I see a guy on here using a small file to relieve the theads on a Bennelli M4 2 shot extention. let's go get all that stuff available on your store site..please?

[@SOSdoorgunner69]

Ok so...I purchased your stock kit and plan to use it with only the three position buffer tube. But I noticed that your butt stock has a button, to release or lock the stock in position Can I expect that you are selling the same one? I purchased mine from Optics planet and it says it's a Panzer product. Something seems fishy here. I don't see anything that appears to be a button release on the pictures on the ordered one. I am a bit skeptical that the unit you used for video may not be the same one you are selling as a kit. The buffer tube has nothing to do with that as I don't need 5 positions. 3 is plenty for storage or transport. cam anyone who has purchased one chime in? I know it's priced right but something seems odd. I guess I'll know when it arrives as they have been really slow as of the last few months. Also, Do you have your own Panzer store on line so we can get these after market items? seems like there are virtually no one making affordable after market items. mag ext. bolt charging handles. etc. thanks for any info you or someone on line can give.
