Buy a  real used m4 barrel .Can find them at a decent price

That sucks that it broke and they can't hook you up with a spare part!

I think these are disposa-guns when broken - Too bad they are cool.  Buy a pair of them if you want spares.

That seems like a missed opportunity for SDS and the other importers.

Have you tried local shops or gunsmiths?

Contact AKSA arms?

Silver soldering is done all the time by gunsmiths for sights/rib Installs right? Give John Thomas a call/email. His prices are fair.

Follow Up: Black Aces will be sending me another stock. I also purchased one off eBay. Looks like it uses a proprietary buffer tube assembly for the wood stock version.

I ordered the Panzer M4 tube from classic firearms in case I want to swap it. I need to find my propane torch. I'm sure there is thread locker.

How bad are the turkinelli adjustable stocks? Black Aces sells one but they all probably come from the same factory

DLG arms makes a shit ton of furniture for Turkish guns

I found a place on GB that has some cheap barrel assemblies, probably turkish as well.

Oh neat. Hope it works out

Link?

Looks like the barrels are ported, and chrome lined. They use cerakote though

Nice!  Thank you!

Looks like the choke is ported, not the barrel itself.

Oh, good catch thanks

I just submitted a question to the seller to get clarification on the "ported" description.  I'll post the response when I get it.

I wanted to post up a suggestion based on my own experience with a Turkish Benelli M4 "clone'.  My particular shotgun is an AKSA S4.  From day one I have experienced all of the typical malfunctions that have plagued many Turkish M4 clone shotguns.  I have thrown time and money at this shotgun in an effort to make it consistent and reliable.  Yes, I am probably guilty of "throwing good money after bad", but honestly I have enjoyed tinkering on it.  Along the way I have also learned a great deal about the Benelli M4 and my Turkish copy.  Note: I am NOT a gunsmith or a firearms expert.  I'm just an amateur tinkerer and enthusiast that impulse-purchased a cheap Benelli M4 copy and was determined to either make it run well or destroy it in the process.  Fortunately, I am happy with my recent breakthrough.  I could post multiple pages about some of the things I've tried to address the malfunctions, but nothing really made a significant improvement until now.

If you are having random and irregular malfunctions (FTF and FTE) check to make absolutely sure the gas pistons move completely freely in the gas cylinders.  Both pistons should slide back and forth without any resistance and you should be able to spin the pistons in the cylinders while sliding them back and forth without any resistance.  Make sure they are clean and dry before you check this.  If your pistons are moving freely and you are still having malfunctions, I really don't know what to tell you.

If your gas pistons are binding up (like mine did) you may need to polish the rings of the pistons.  If you look at the original Benelli pistons, the pistons appear (to me) to have very finely machined surfaces that "seal" against the inside of the gas cylinders.  The genuine Benelli pistons I've seen pictures of look like they are nitrided with raw but very finely machined edges on the piston rings.  The Turkish copies that I have seen (including those in my S4) have what looks like an NP3 or nickel-boron coating.  The coating on my gas pistons was uneven and did not appear nearly as precise and consistent as the machined rings on the Benelli pistons.  This is apparently what was causing my gas pistons to bind in the gas cylinders.  

I polished the gas rings with 600 grit, wet-dry sandpaper.  It did not take long and I went very slowly - checking the piston movement in the gas cylinders frequently.  I originally tried 1,500 grit but that seemed like was going to take years to remove any material.  I also tried 800 grit but that seemed too fine also.  I finally saw results with the 600 grit in what I considered a reasonable amount of time.  

To polish the piston rings, I applied machinist's blue to the edges of the gas piston rings and let it dry for a few seconds.  Then I slid the piston into one of the gas cylinders and pulled it back out.  I chucked the piston in my cordless drill on high speed, and held the sand paper in my hand.  I sanded the piston rings for about 10 seconds (each time between fitment checks) applying additional pressure on the piston ring or rings that showed the most contact with the machinist's blue. Then I slid the piston back into the one of the two gas tubes to check the resistance.  I repeated this process until the piston moved freely in both gas cylinders.  Then I went through the same steps on the other gas piston.  

I have now run about 400 rounds with only 2 FTF malfunctions.  Neither of these failure to feeds were like the ones I was getting before I polished the pistons.  They were consistent with a dirty gun which makes sense as I had not done a full cleaning in probably 800 rounds or so.  Most of the last 400 rounds was cheap, low-brass #8 bird shot.  I did also run about 50 rounds of high brass 00 buck and a few slugs just to make sure my amateur gunsmithing didn't adversely affect how the heavier, higher pressure rounds ran through the gun - no problems there either.  

Again, I am NOT an expert so proceed cautiously and at your own risk if you do this.  Polishing the gas pistons seems to have solved my FTF and FTE malfunctions on this particular gun.  I should note that before I tried this, I had also replaced the extractor and extractor spring, shell catch and shell catch spring, and the recoil spring with genuine Benelli parts.  None of these seemed to make much, if any, improvement on my particular gun.  YMMV  

Regarding the wood Aksa S4 from Black Ace's. A Panzer M4 5 pos tube threaded right on. Removal was easy all it took was a bic lighter and I put the tube in a vise with some wood pads. I was able to unscrew it without much effort at all.

The Turkinelli field stock and the mesa tactical now fit with no issues.

The Panzer M4 tube seems decent quality and comes fully assembled with spring, plunger, c clip, etc. Also checked it with a magnet and it's made out of steel

Regarding the inside of the AKSA S4, does yours look like this?

Looks like this area is in the white. Also was just curious about these lines? Is this normal? They don't look like cracks/fractures atleast.

Stupid question I know, I'm new to this platform. Attached File

Also regarding the buffer tube how far do you usually go? I read 8 rotations and it doesn't seem to mess with the trigger group/housing.

Edit:
I was reading more on this. If there is any light gouging it's from improper reassembly. Doesn't explain the lines though. I was pretty careful but did leave a few very tiny marks.

Honestly it's better to learn this on a cheap gun vs the real thing. I took it apart for the first time today. All I did previously was swap the handguards out.

Per the seller - the barrel is ported.  Also, the barrel is not available without the ports.

Interesting.

I ordered a KZ Benelli Picatinny rail with integral T1 Mount. Ordered it on Ebay 2nd hand but NIB for $30 (didn't give Botach a penny.)

It looks to be good quality but:
-Screws are too long. They need to be filed. It's almost impossible to find 8-40 flat head screws. A majority are Fillister or cap head. To save you some searching though Scalarworks sells some that should work. I'll update you on that. Im hoping there will be enough thread engagement.

https://scalarworks.com/shop/everything-else/sync-screws/
Option #2: Sync 1/2/3 C Screws

I needed some for my mossberg 590 anyways. so we'll see how well these work.

-Optic Screws are proprietary in regards to head diameter. I had a hard time sourcing these for a battlesteel mount I purchased awhile back. Botach Customer Service sucks. Don't count on the lifetime warranty. There is a reason these cost $40-$50. Great quality, but shit company backing the product.




For the money it's hard to complain. For the love of god just don't lose the M3 Screws.

The scalarworks screws were too short so:


-I filed down the included screws, hit them with cold blue, rinsed, dried, degreased, and added blue loctite.

Primary Arms advanced micro will 1/3 lower cowitness.

I'm not sure what I'll be using to picatinny rail for but it was a decent value.

I'm still debating on whether to go with the scalarworks, or mesa for the integral shell carrier. Not a huge fan of RMR's, though, and I'm not certain of any 1913 mounted red dots that would cowitness with the irons. Anyone have a recommendation?

Just got an urbino installed, it's a hair short without body armor, but fits perfect with a PC or heavy winter clothes. Has a couple sharp edges where it fits against the trigger guard, and I'd prefer a more vertical grip angle, but it's an improvement. Definitely worth the money to get the cheek riser, the field stock was way too low for the irons, let alone optics.

I have read some of, but not all of this thread. Thought I'd chime in because I just bought one of the new run Panzer M4 clones about a month ago. According to Panzer Arms it's 100% compatible with Benelli parts though mine is still fully stock.

I have about 150 rounds of various buckshot with a smattering of target loads and it's been perfect. The build quality is quite a bit better than I expected for 450 bucks.

The one issue I had was that the buffer tube/stock tube came a little loose which took 3 minutes to snug back up and I'm confident it'll stay that way. It has a steel tube for the strut to run in molded inside the polymer skeletonized stock.

The whole thing is otherwise tight and smooth. Unless it inexplicably blows up or falls apart for some reason, I'm very happy for the price.

They are discontinued but still in stock on Amazon if you want a Scalarworks/T1. Normally I'd opt for quality stuff but I couldnt justify a $140 mount on a gun I haven't put through the paces just yet.

In regards to Shell Carriers I prefer velcro cards honestly. Not sure if anything will cowitness with Picatinny, but a QD Mount solves that.

The Mesa is still sitting in the box. Honestly the Field Stock knock off I purchased is growing on me. I'm thinking of buying an IWC Mount n Slot for it.

I'm not sure where things are headed in IL. So I'm holding off on installing the mesa stock/Dave's mag tube.

How is that Panzer stock holding up? I purchased the buffer tube, was just curious if the adjustable stock is quality? Cuz damn I love that look. I heard the roll pin had a habit of coming loose. Going 1 size up might fix that issue.

This one is actually fixed. I thought I might want a bit shorter LOP, but for me at least, it's good with this stock. The cheek piece is adjustable though. I don't think I'm going to change it after all.

The main mounting bolt is what loosened up on mine and just a perceptible hair. There's two hidden mounting screws in the butt pad. You take that off, or just one side and swing it out of the way and there's a large allen head bolt. I just just snugged that up real good.

The stock feels kinda cheap-ish, but is super solid. It doesn't flex or move around at all.

I like the look alot too.

Who has a good price and in stock for Panzer Arms Retractable stocks and Pistol Grips?

Classic Firearms has a good price right now in stock, PSA and Atlantic also in stock.

The problem with the retractable stock is that the tube and grip assembly have to be purchased separately from one another which adds a hundred plus dollars to the cost of the gun. I'd probably wind up adjusting it to pretty much the same length as the SKELETONIZED STOCK that came on mine anyway.

The Panzer I got from Buds 2 months ago had the correct tube already installed on the shotgun.  Once I took off the stock that came on it the collapsible stock and new grip went on in its place. I was lucky enough to get the stock in a box with the purchase of the Panzer M4.

That was 450 bucks? If so, you got a better deal than I did
How do you like the shotgun?

I absolutely love this thing, but I need to train with it more.
AT THE RANGE FRIDAY

From what I have shot it, I like it alot. This is my first semi shotgun to own next to my Mosberg pumps but I do like it and the stock set up. Just need to shoot more.

Regarding the AKSA, The receiver seems to be pretty soft aluminum. Kinda marred is slightly swapping the tube out. Material kinda peened with ease. (Isnt really visible with the stock on). Curious how well these are holding up?

I'm rather skeptical about it being 7075

I would definitely use caution in regards to the optic rail if you replace it. Maybe go with only 15 inch lbs and let loctite do the rest.

Worst case scenerio, you can easily get your money back by parting one of these out.

So, took the plunge! Panzer M4, nickel phosphate with the skeleton fixed stock.

Before we get to my experience so far, a HUGE thanks to everyone on this post that has posted their experience, as a first time shotgun buyer I have learned a lot and appreciate that opportunity.

Ok, first my sample of one, the fit and finish are very nice. Time will tell how it wears, but the assembly surfaces seem to be clean and unaffected and I have had it apart more than a few times as I learn about this firearm. Like others I can not believe the length of the stock,the fixed skeleton stock has an un-notched tube under the “adjustable look” outer tube. To fix this, bought a Mesa Tactical stock.

**** In addition the original Panzer stock bolt it is too long to use in the Mesa install and the threads on the Mesa screw that is included are not compatible with the threads in the end of the internal buffer tube - sigh. I did not see this anywhere in this thread so even though I have access to loads of grade 8 hardware, this was unexpected.****

The only other physical disappointment is the front sight protective ears. They look like someone made them in a vice with a hammer. Bolt carrier and pistons look good, no heavy grease.

On the assembly and disassembly- all worked as it should, no issues with tight charge handle or any other parts, and they all looked clean. A few chips were found inside when I cleaned it but nothing I have not found in times past in every other manufacture that I have purchased including Glocks, Rugers, Smiths and HK’s.

When I get time to shot, I’ll post more….

Thanks again to the early adopters and those that fought thru the early issues!

Mine was too thin for the sight to fit into it so I replaced it with a Benelli part.

That is my long term plan if it runs.

Mesa stock has another issue. Buffer tube is about 1/8th of an inch too long. Stock has a small gap where it meets the receiver. Not sure if I’m going to mess with it anymore until I know it doesn’t have any other issues since I have not shoot it yet. Wife saw the shells and is having second thoughts on trying it out - maybe later she said…. Gonna put it back to bone stock until then.

Anyone have both the unnotched and notched buffer tube, are they the same length?

For which gun? The Panzer?

The smooth tube on my AKSA was too long for the Mesa

Ordering a notched tube for the Panzer M4/Classic Firearms lets me mount the stock. The entire tube assembly for $40 was a good deal. Especially if you compare it to the price of legit Benelli parts lol.

I can measure the notched tube for you if you want.

Yes, I have the Panzer, but I think you already answered my question. I will probably just order the 5 notch tube, might just go all in and get the Panzer stock as well….but then 922r…..or do I make a spacer…….

Interesting.  The Mesa Urbino stock fit my AKSA S4 with the smooth recoil tube just fine.  No fitment issues.

Should of mentioned mine was the wood stock version imported by black aces

Is that an "AKSA" made unit then?  Is AKSA making them for Black Aces?

Made by AKSA, imported by black aces. Even had an AKSA branding tag attached to it.

Iirc SDS stopped importing the AKSA.

I think the buffer tube is proprietary to the wood stock. Wouldn't work with a polymer field stock either.

Swapped out just fine though.

Ah, ok. didn't know that.  Glad you got it swapped out.

Well, decision made. Mesa is going back. Notched tube and Panzer stock on the way Dave’s tube and follower and some other goodies are in bound.

I see a new player, or at least new to me.  The MAC 1014 wood.  Looks kinda neat, an M4 with traditional wood.  Less scary looking lol.  

Here is a pic.

Ok...got two PWA M4s about 3000 numbers apart.

Got two collapsible stock kits from PSA... since both guns already had notched buffer tubes we thought we were gtg.  The older gun has a slightly different thread pitch while the later gun screws right on.

I'm talking about the nut that goes in the pistol grip and locks in into the tube.


Any idea what the other pitch might be so we can find the correct nut?

Dude that has to be the AKSA, also Im gonna say fuck Black Ace's still havent gotten my replacement walnut stock. Im hoping SDS imports these for now on as part of their MAC series.

Ok, for those that have not taken ‘the plunge’ , my m4 with skeleton stock had an un-notched buffer tube, purchased in late June of 2023. If your plan is to go adjustable stock that is another $55.00 to your base. Just wanted to pay it foward.

And by the way, the fixed stock buffer tube is actually 1/8th an inch longer than he notched buffer tube. I tried a Mesa Tactical stock but the tube as too long, could not tighten it up and the two tubes were different lengths……..what a PITA.
