"Over Gassed" AR's Fact or Fiction? Other Perspectives

Ok, seriously....

When and more importantly WHY did the ejection pattern become the end-all, be-all sign of AR operation?
When I am across the border with Meal Team Six in my plausibly-deniable ambush position I need to know where my empties are going to land so I can ensure I leave no trace.

I am also a liar.

Mk 13 Mod 0 stock

Second picture below is a new barrel compared to an original take off. All dimensions were taken from the original barrel and an original blue print.

Just like @ilikebmxbikes said in his post above, these are the absolute best Mk13 Mod 3 barrels that collectors/cloners can possibly get! If any of you need a Mod 3 barrel, contact @crazynoto asap and get one the list. Who knows if this will be the last run or not, so grab 1 or 2 while you still can!

If you already have a built rifle, it's still a good idea to get in on this deal and pick up an extra barrel. It's pretty easy to shoot out a .300WM barrel, so having a spare barrel or two on hand and ready to go is a great backup option to have. And if this turns out to be the last run of these barrels, any loose barrels will drastically increase in price over the coming years. Just a few other things to think about.

It was extremely surprising when @crazynoto found his original Mod 3 barrel, since it's currently the only original Mk13 Mod 3 barrel in private hands. He sent me tons of photos and we spent countless hours going over the smallest of details. That analysis paid off because we discovered exactly how the original Mod 3 barrels were made! This isn't just a look-alike or something that's close to the originals, it's an EXACT reproduction of the original Mod 3 barrels! This is the only place to get one, and @crazynoto has gone through great lengths to order the barrel blanks in the exact specs he needs to make these clone barrels.

Once a gunsmith installs this clone Mod 3 barrel on your rifle and does the vertical gate latch cuts, it will be a 100% reproduction of the finished original military barrels. The barrel blanks come with the barrel journal already installed, so @crazynoto has already taken care of the most difficult part of the barrel that needs to be precisely duplicated.

Please ask any questions in this thread. If anyone needs a Mod 3 barrel or 2, don't pass up this opportunity!

"Over Gassed" AR's Fact or Fiction? Other Perspectives

I agree that it is a sign, but for me I don't really care where it ejects if it does so reliably. My favorite upper consistently throws them at 1 -1:30 but has done so for a couple of thousand rounds. At that rate I won't touch a thing.
For many, it isn't an issue. Assuming all is well with the bolt, 1-1:30 is a sign of pretty aggressive gassing. As said, for many, it isn't as issue, as long as it keeps running with your chosen ammo.

So far, you've had reliability for 2000 rounds. Although overgassed rigs are generally more reliable than undergassed rigs, I'll bet your rig is seeing some pretty accelerated wear. Can you feel that groove in your cam pin yet? Notice some premature rounding on your bolt lugs? Ejector swipe marks on the brass? Perhaps partially torn rims on the cases?

Do you run steel cased ammo? Although your rig may be an exception, I'd lay odds that your rig chokes on steel cased ammo due to stuck cases.

I don't know how long you've had your AR or how many rounds you typically put through it, but for me, 2k rounds is a month of shooting and if I ran my setup that overgassed, I'd be replacing parts pretty often.

If you're considering going suppressed, I highly recommend some gas mitigation before doing so. Your rig will beat itself to death in pretty short order, if it runs at all.

Can we talk shooting technique?

How DARE I ask people on the internet what they do when training exist in the world.

Asking people what THEY do does not cost me any ammo. Stop being a snob. People can still discuss technique when live classes exist. Sorry but such an asinine reply
Well you asked a question about a very basic thing in shooting. I have seen too many new shooters develop bad habits trying to learn from the net on there own

I suggested a top notch shooting school Rifles Only that has a long history of making great gas gun shooters

Of course it costs nothing to ask how to shoot, tie your shoes etc but sometimes a little professional marksmanship instruction pays huge dividends

In your case have at it. I

Drive through masses of pedestrians its now a global thing

If those idiots would get a truck with a V-plow... and weld on some pointy and sharpy things, they could do a whole lot better.

Running some plastic 5 mph bumper into folks is just so un-creative.

Get a Fisher 9 foot V and weld some cleavers and steel punjii stakes on it... and now you are talking!

So lame...

Kahles vz ZCO

I run a ZCO and even I find the hyper-defensive nature of the ZCO lads to be a bit much a lot of the time.
ZCO SuperFans and USO Haters are different sides of the same extremist coin.

If something works for someone, so be it.

Optics judgments as an exercise in religious conversion fascinates me.

Kahles vz ZCO

Unbelievable :rolleyes: :eek:..........


Maybe he wants ZCO to leave the forum just like the other manufacturers... I have sold and handled thousands of ZCO's since 2019, I track potential issues and look for trends. Not one off stuff, if there was a consistent problem than I'd discuss it with Jeff on our weekly calls to help me get through these backorders.

Do you really think I'd put my name and reputation on a product with a consistent problem? I don't need that type of headache and have dropped products and manufacturers with consistent QC or CS problems.

NEW! MDT SEND IT GEN2 \\ Electronic Rifle Level

Hello from France
Can you give all three dimensions with and without mount in order to know which model will fit.
Do you mean depth is 31.3 mm ?
On the following picture, the 16 mm height seems incorrect, it should be around 19 mm.
Or maybe 16 mm is the height above the inside of the picatinny rail…
Thanks

View attachment 8677809
Why do you ask that? In the very picture you included, it shows the thickness of the led unit as 12.7mm. Is it a stretch to imagine that 3.3mm is added using that particular picatinny mount?

Maybe this picture from their site can help:

Edit: that’s a CR2032 battery in the picture for size comparison.

Or go directly to to the page where they are for sale:

Kahles vz ZCO

As promised, here are some more links.

Despite these issues, I’d prob still choose ZCO over Kahles due to their apparently superior customer service. Doubly so due to Kahles/Swaro’s lawfare about their FOV patent #FovGate. (Swaro owns Kahles)






So what is your motivation with all this? I spoke to or have been involved with many of these personally. You think what's posted on the forum is the whole story? I have call logs and PM's that fill in more information Dude give it a rest...

Some of those people are not even on the forum anymore.

If you truly have a concern then call ZCO and Jeff himself will answer

Can we talk shooting technique?

I don't do NEARLY enough prone shooting. I really need to focus a lot more on that. If you think about it its probably THE most important to master too. The floor will always be there for you (assuming u arent on a mountain) but you may not be able to shoot off a car, tree stump, etc. I need to do a lot more of that.

Thankfully it was DRILLED into my head as a new shooter to always try to get the buttstock as close to the center of your chest as possible. So I never used that angle technique in the pic above.

I completely agree about the scope rings!!! Anything lower than 1.5" is just torture on my neck. I have never gone as high as 1.93" but if its more comfy why not?? As long as the ballistics software reflects it doesnt matter at all (assuming u arent trying to use a thermal clip on or something)

Did you ever see that MDT video when they elevated the scope to a RIDICULOUS height just to prove it doesnt matter at all? I saw that and thought "no more sore neck for me" lol
I did not see the video. Got a link?
