I managed to purchase for my self an ACOG EREK cantilever adapter.
Now to be honest, I’m not exactly sure what EREK stands for. I’m guessing something like Eye Relief Extension Kit.
So why did I buy it? Because I wanted one. Some time back, I saw some pictures of the USMC trying a cantilever mount for the ACOG on the M16A4. Since them I have wanted to give it a try.
When you read about people complaining about the ACOG, the first complaint is always price, the second tends to be about the short unforgiving eye relief. Once you take that short eye relief of the ACOG and have to mount a BUIS behind it, combined with a fixed stock, it can be annoying. Personally, not only have I gotten used to it, I am rather fond of the ACOG mounted forward as I shoot nose to the charging handle.
So at some point the USMC had some adapters made up that moved the ACOG back and over the Knights 2-600m rear sight. This makes the ACOG easier to use with the A2 fixed stock. Now I tried to find pictures of it in use again, but I was unable too. My guess is that the USMC tested it and for what ever reason decided not to use them.
Why? I don’t know. Perhaps raising the ACOG up make it more unacceptable to damage or abuse changing the zero. It might not have been worth the cost. Or someone might have come to their senses and said use the M4 instead. In any event, I have one to use now, and it is rather nice. It lifts the ACOG up enough that the charging handle is easily accessible, and moves the ACOG far enough back that you don’t need to crane your head forward for nose to the charging handle.
The really great thing about being passionate about firearms, is that you research and stumble across unique accessories and gear. This is exactly what happened when I stumbled on Bad Element Co. LLC (www.badelementco.com) AK magazines. I have been on an AK fix for a little while now and it has been over a decade since I owned one. I recently purchased a very nice Bulgarian AK74 and have been testing several aftermarket accessories with it. When I ran across Bad-Element I had to get one of their 20 round AK Tanker magazines. I absolutely love 20 round magazines for rifles. As soon as I received the AK74, I started to research 20 round AK magazines. I found original AK 20 round (Tanker) magazines were extremely hard to find or get in 7.62×39. Add in the 5.45×39 AK74 round and I found they were almost impossible to get. I made contact with the owner from Bad-Element about getting a 20 round 5.45×39 Tanker magazine. Since I already had a few Russian Izhmash Plum magazines, I thought a Plum Izhmash 20 round magazine would go very nicely with them.
When I received the Bad-Element custom 20 round Tanker magazine, I quickly started to compare it to my surplus Russian Plum Izhmash magazines. All of the markings on the magazine were identical and I could easily tell it was a quality Izhmash Plum surplus magazine. I’m not really sure what it is, but as soon as you put the 20 round magazine in the rifle, it just looks and feels better in your hands.
Custom Order Magazines:
Bad-Element does all kinds of custom work to all makes and manufactures of AK type magazines. Bad-Element takes existing 30 round AK magazines of all types and custom cuts them down to (20), (15), (10) or (5) round count magazines. In-fact, Bad-Element also does AR15 magazine custom work, for those who live in Communist high capacity band States. So check out their full line of magazine services.
There are several ways you can get your custom magazines from Bad-Element. (1) You send in your AK magazines and Bad-Element cuts them down per your round count specifications. (2) Purchase magazines on-line and have them shipped directly to Bad-Element for custom work, then they will mail them to you when finished or, (3) You can purchase already modified magazines directly from Bad-Element.
I set off to the range after obtaining a decent quantity of ammunition, supplied by (www.ammoman.com), to test out the function and reliability of the Bad-Element magazine. I had 510 rounds to run through the Magazine.
The great thing about 20 round Tanker style magazines, is their ease of use while manipulating your rifle. With a 20 round AK magazine you get the same advantages you get with a 20 round USGI AR15 magazine and more. (1) It’s compact, (2) rifle fits in smaller spaces and cases with a loaded magazine, (3) still has a decent round count and (4) with the AK, it is much easier to manipulate the charging handle from underneath the rifle, with your support hand.
I really did not keep exact track of the round count I put through the Bad-Element Tanker magazine but it was several hundred rounds. The Bad-Element magazine performed flawlessly and I had absolutely no issues with reliability. It loaded and emptied the rounds just as you would expect from any quality military surplus AK magazine.
Takedown/Quality of Work:
Nothing has changed after modification of the magazines. Takedown of the magazine is the same as the original 30 round magazine. Bad-Element has cut the magazine and spring down. The magazine still uses the original surplus follower, spring, locking plate and floor plate.
The quality of work and attention to detail in modifying the magazine is very nice. Bad-Element has really paid attention to the little things to make the magazine look nice. The magazine has a smooth side cut channel at the bottom of the magazine for the floor plate to slide into.
The cut down magazine spring is very nicely done. Looking at just the end of the spring where it locks into the locking plate, you cannot tell which one has been modified. Bad-Element has taken the time to slightly bend and taper the end of the spring, to match it up with the original 30 round design. After talking with Bad-Element, they advised they use to cut down the bottom of the spring, but now cut down the top of the spring, as it was easier and faster to do. I still could not tell the difference.
I am very pleased with the Bad-Element custom magazine. It looks great and has been 100% reliable. If you have an AK of any type, I would highly recommend getting a few 20 round magazines. If you follow Rob Ski of AK Operators Union, you will see he runs Bad-Element Tanker magazines from time to time. He is usually the first to call out “shit” in the AK community. Since he is running them and is more of an expert than I am with the AK, I think this is a very strong sign of Bad-Elements quality. I will be getting a few more of the Bad-Element custom cut magazines in the near future. As soon as the Magpul Pmag 5.45×39 AK magazines get to me, I will be sending them in for 20 round conversion. Bad-Element also has an Instagram page (Bad_Element_Co. Instagram) where you can follow and contact them about magazines.
About 10 years ago the ARFCOM retro forum had not become the price driving monster it would end up. During that time it was still still possible to find some pretty rare parts on ebay and various places. Some of those parts could be made into a full weapon minus the lower of course. That is the goal for most of the retro builders. Ideally they want all original parts they can get to finish the gun. A lot of people manage to piece together a gun by finding all the correct parts. Obviously I am leaving out the full auto lower, but when I say all, I mean everything but that lower and whatever other parts that would risk crossing the absurd rules.
What really sticks in the craw for a lot of people, is getting 90% there. Ewww that has to burn! You get something super rare and cool and you just can not wait to post pics of it all over place at the gun prom! But. You just can’t. Get. It. All! So what do you do? Give up? Sell it all off to some other guy who still has a hope of finishing it up?
Nope. You go online and find some one who knows a guy who knows a guy and just have the parts you need made from scratch of course!.
So now we come down to the “rest of the story”. The two guns shown are of course Colt M2231 post firing weapons. An oddball from a period of time where the military wanted to have something to fire from the side holes of a Bradley. You can look up the details yourself but it basically a M16 simplified down and with a really high cyclic rate meant to be used from the Bradley. There are a few variants of it but one in particular more or less stands as the standard model as far as looks and recognition goes. A guy who ended up becoming a dear friend came on the retro forum one day after ending up with a hand full of M231 parts from some auction and wanted to finish it up as it was not something being done at the time. He was really stuck on a couple of parts that seemed to be impossible to find and was out of options or ideas. I happened to wonder into that thread and after seeing the almost finished weapon, really got hot to see it completed.
I contacted my friend who is a skilled machinist about the possibility of making that part for the arfcommer. After some emails and back and forth the project was on its way.
The major hold up for the arfcom retro guy was the gas block that was also that part that hooked into the vehicle. No one could find measurements or even a picture to show it from all angles and sides. Some found some specs some where and I sent it on to my machinist friend. Just using pictures found online that no one took for the purposed of making a copy of it and eye balling it, my friend came up with a plan. Below is a picture of a real one and the fake one made up by my friend, who has made an appearance on this website a few times over the years.
Everyone has heard of the 10 foot rule or some version of it. Well most will agree that if you have never handled a M231 yourself and even if you did you likely never cared, this copy would most likely pass the 10 inch test for anyone other than people very , very familiar with it
You can see the places where the fake , faked it. Mostly this is a result of making a copy from pictures.
In this case, the length of the barrel gives it away. The real M231 upper has a slightly shorter barrel. The longer 16 inch barrel is used as the variant with stock, makes for a legal carbine. Real M231 upper with shorter than 16 inch barrel is a “Pistol” so as not to have to get into NFA laws.
The machining to make that gas block took a few months and trial and error. Some experimenting had to be done with the gas system and gas tube. A gas tube had to be cut down by the machinist and a one of a kind gas system made. We tested fired it one night and it was feeling of real accomplishment.
The gas block above is pictured in the white. The machine shop my friend worked at did not have an ability to park’ it and the owner received and and sent it off to be finished in the appropriate shade for retro looks.
it was a lot of effort to pull this off. I did not mention that I and my friend live in Ky and the owner close to the other end of the country so much phone calls and emails , shipping and a lot of effort by guys on Arfcom retro forum went into getting this thing together. It tunred out pretty good I have to say.
Of course it was all kind of a waste because a month or two after it was all completely a real completely M231 came up for auction on gun broker and the owner of the M231 bought the complete upper. If he had only waited ! It was all worth it regardless. things were learned, some one worked on something at work he was not supposed to. life long friends were made and some esoteric M16 retro parts skyrocketed on ebay ever after. Good times had by all.
Bellow I am posting some more picture of the oddities M231 parts. Most are the major parts that are a hang up for any one pondering putting one together. At the time, I recall some other machinist was making copies of some of these parts.
