The short answer is that they are the same thing. The bullet’s diameter is 0.50″ which is 12.7mm and the case length is 1.65″ or 42mm. The reason you see some vendors say they have something to sell in 12.7x42mm is they are trying to avoid a trademark problem with Alexander Arms.
Bill Alexander, of Alexander Arms, did all the engineering to bring to life both the round and the AR components to use it. He also trademarked the term “.50 Beowulf”. As such, anybody who wants to sell something and refers to it as being for .50 Beowulf would need to get the permission and/or license the use of the term “.50 Beowulf” to avoid legal problems. So, a lot of vendors use the generic metric designation of 12.7×42 to avoid legal hassles.
With that said, bear in mind that not all engineering is equal. I have never had a problem with Alexander Arms parts but myself and others have had plenty of headaches with 12.7×42 components from budget AR vendors who haven’t done the engineering. In nmy case, it was poor extraction with a Radical Arms bolt and extractpr. So, buyer beware and research a vendor and their offering before you buy plus make sure they are reputable in general in case you need support. For example, Satern worked great for me and I wrote a blog post about the build.
Conclusion
So, short post this time. 12.7×42 and .50 Beowulf are the same round with different descriptions but be cautious to check out vendors selling parts using the metric designation. Some of them are selling junk so search for current reviews of products before you buy them.

The typical semi-auto AK trigger has four parts – the trigger body, disconnector, disconnector spring and pin. Installing it can be a challenge because you need to properly align the disconnector while sliding the pin through from one side of the receiver to another. For me, with big hands, this task takes more effort than I want.
This is your typical semi-automatic AK trigger group. On the left is the trigger body, top right is the disconnector, under the disconnector is its spring and at the bottom right is the trigger pin. The challenge is getting this all assembled inside of the AK receiver as the pin needs to pass from one side of the receiver, through one side of the trigger, through the disconnector to capture it, out the other side of the trigger and finally out the other side of the receiver. Trying to get it all to align inside of the trigger takes some patience.
The Solution – Use A Slave Pin
There is an easier approach. We can slide a properly sized dowel pin to serve as a “slave pin” during assembly to secure and properly align the disconnector and trigger outside of the receiver. This simplifies life tremendously. The unit is assembled outside where you can see what is going on, is lowered into the receiver and then the actual trigger pin is pushed through and it displaces the slave pin – the slave just exits the other side of the receiver.
This is the slave pin. Note how one side is beveled more than the other. That is the side that is inserted first. The bevel helps move things around during insertion and then the 5mm body provides the actual alignment for the trigger pin.This is the assembled trigger group with the slave pin holding it all together.Normally this would be in the receiver but I want you to see what is going on. As the trigger pin is inserted, it pushes the slave pin out of the way and it exits via the opposite receiver hole.This photo shows how when the trigger pin is fully inserted, the slave simply drops out.This is an ALG semi-auto trigger and you can see how slave pin is exiting the receiver as the trigger pin is installed. So there’s the end result. A slave pin makes a world of difference. Note, that is one if our fire control group plates retaining the trigger and hammer pins.
If you’re like me and want an easier way to install AK triggers, these new slave pins are the way to go!

One of my favorite move lines comes from Aliens when Ellen Ripley says, “I say we take off and nuke the entire site from orbit. It’s the only way to be sure.” While I would like to do that with mosquitoes, it’s just not an option currently.
Not on the table for mosquitoes yet though it does sound effective. The collateral damage is hard to justify though 🙂
This will be our third year using it and I just applied our first dose the other night – 1oz Talstar per gallon of water and than I go spray it on the bushes, around the buildings, under the eves etc. When I went to buy more Talstar off Amazon, they would not deliver it to my area and never really explained why so I figured I better blog about where to find it and also the My 4 Sons sprayer that isn’t on Amazon any longer.
This is the 3/4 gallon (96oz) size Talstar P Professional insecticide by FMC. I have an acre and a half. I use 10-15 gallons of spray depending on what all I am treating and how heavy I am applying it. That means I use 10-15oz of Talstar per treatment (1 oz TP to 1 oz water).
Buying Talstar P Pro Insecticide
My big problem this year that I wanted to make you aware of is Amazon – at least in my case they will not deliver it to our address. I’m getting increasingly frustrated by Amazon so I now buy it off eBay:
My 4 Sons M4 Sprayer
The next thing I want to do is give you a “one year later” report on the M4 sprayer made by My 4 Sons. I’m happy to report it has held up great and their customer service was exceptional. Note, I definitely drained it completely before freezing weather set in.
This is my actual sprayer the morning of 5/2/2020
Here are some lessons learned on my part and a couple of minor issues I encountered:
I bought way too much hose when all I needed was to just tow it around like a golf cart and spray stuff. I took the extra hose and saved it just in case.
I bought all kinds of sprayer gizmos and all I use is the wand. It has a brass tip, is adjustable and worked just fine for me.
The red elastic straps they provided did not hold up – the tank would fall of the cart. I just went to ace hardware and bought some 1″ nylon straps with buckles and cut them to size. I told My 4 Sons about what I did and am not sure if they changed how they are securing the tank.
One wheel broke and My 4 sons promptly sent me a replacement at no cost
The gasket on the lid was goofy and they sent me an improved model at no cost
This Spring I could not find the battery charger and ordered a replacement part from them. The price was reasonable and on their website – of course I found the original shortly there after.
As mentioned, I’ve already done my first application this year and the unit is doing great – they aren’t on Amazon any longer though. I want you to know they are a reputable firm with a good product and customer service. I would recommend that you go direct to My 4 Sons.
Just to be clear, Talstar will work in any sprayer – it’s pretty much the same viscosity as water so any pump sprayer – manual or batter powered – will work. I needed something bigger because of the size of our lot.
Conclusion
The Talstar P Pro and M4 sprayer are a great combination that I would recommend to anyone trying to deal with mosquitoes. It’s cheaper than a service and way, way more effective than the cheap stuff you buy in a store.
I hope this helps you out.

In 2019, I bought a PSA AK-V and really liked it. The little pistol caliber carbine was reliable, accurate and fun. I did an initial four blog posts about the purchase and then one on converting it.
Because I liked the AK-V so much, I started paying close attention to reports about the improved quality of the PSA AK line in general. I read the posts in the Facebook AK-47 group regularly and guys were reporting how happy they were with the GF3 series and the new AK-E that would be the PSA premium rifle with forged trunnions, nickel boron coated carrier and bolt plus a premium cold hammer forged barrel from FN. It definite caught my attention so I decided to monitor the situation.
Out Comes Rob Ski’s Videos
Rob is the creator and host of AK Operator’s Union’s video series. He was born in Poland and served in the Polish Land Forces as an infantryman. Then, when his family immigrated to the United States, he joined the US Army and was a paratrooper. In short folks, he’s the real deal when it comes to his opinions and experiences. If you’d like to read more, click here to read a 2014 interview.
Some people like Rob and some don’t – I like Rob. I think he’s a character and like his videos. I also respect his opinions. At any rate, he did a series of videos on the AK-E and the first one caught my eye because of the title “I hate new Palmetto State Armory AKE” – here it is:
He then posted an update after 2,000 rounds:
One at 3,000 rounds
After even more rounds and after pouring in a bunch of sand while it was running, accurate and Rob was impressed.
Well, between the Facebook group and Rob, I ordered my AK-E and will post about taking it out of the box next.

I thoroughly enjoyed this Japanese video that covers the forging, engraving and heat treat of a Japanese Katana by a Master – Sadatosh Gassan. The video provides a great overview and while it is in Japanese, there are subtitles in English.
What I found most fascinating was the detail of the creation and application of the clay to create the hamon. Sadatoshi-san also is shown carefully engraving a dragon around a plum tree.
He evenly applied the clay and is now drawing the hamon pattern into it prior to the heat reat.Here it iss just prior to the firing.Carving the dragon into the blade.The end result is beautiful.
The Video
I hope you found this video as interesting as I did!

I always love it when folks send me photos of their firearms using our parts. Rick sent in these cool photos of what he calls his “R4 Forgery” and it is using one of our Galil grips.
Very cool Rick!

I wish I had better news but Youtube cancelled the channel for the Kalashnikov Concern so the video is no longer available. I am leaving the post up so at least you can see the screen shots.
Because of the import restrictions of the Russian firm Kalashnikov Concern, Americans will not get a chance to see a cool new rifle just released by them. Their AK TR3 rifle is a civilian version of the modern AK-12 and will be available in both 5.45×39 and 7.62×39 cartridges. [Click here for a previous post that goes into the AK-12 in more detail.]
The AK TR3 is identical to the military AK-12. Note that it has three fire control group pins.The AK TR3 is chambered for both traditional Russian cartridges, the 5.45×39 and 7.62×39
Yeah, I sure wish I could buy an AK TR3 but given the political issues between our countries, that is not going to happen. Regardless, it looks like a very slick rifle and I’ll just have to ogle it from afar.
