If you have recently gotten or are getting a BFG-50, it may have an easter egg on it. This isn't just pure narcissism, by the way. I've had this company for over 30 years and if I'm dumb enough to have to weld my own guns, people are going to know about it! 😆

This is a strobe light that I built in high school electronics class 48 years ago, and it still works! We soldered all the components onto the circuit board, and even made the board ourselves by acid-etching blank circuit board stock. This is how education USED to be!

Where are my fellow 30 Super Carry fans? Kind of joking, because for now this round is still the red-headed stepchild of the industry. It's actually a fantastic idea because it has similar ballistics to the 9mm, but is considerably smaller in diameter. This can get you 2-3 more rounds in your double-stack pistol. As a gun designer, I like the 51,000 PSI chamber pressure because it means that FINALLY we're getting past the old, anemic pressures that were common in firearms 100+ years ago. I know my buddy, @Tobias_Arms likes the 30SC, but what about the rest of the gunners here? If you hate it, why? Is it just the price?

Years ago, when I was a broke bitch, I had a chance to buy some "questionable" .50 BMG ammo. It was from 1949, being sold for 60 cents a round, in sealed "spam" cans in wood crates. I only bought about $300 worth, and later found out it was made by Remington, and was one of the very first lots made with non-corrosive primers! As an aside, many years later the distributor I bought from (Ellett Brothers), bet on Hillary in 2016 and bought a huge amount of inventory. They went bankrupt not long after.

I used to burn ants with a magnifying glass in the bright sunlight. I admit it.

Yes, this is what a good day looks like. Pretty cool to live in a country where you can legally own a Ma Deuce, and M-240, etc. Current military machine guns, owned by civilians.

In a firearm, case stick out is extremely important. In this .50 BMG example, the stick out is .200". You can go quite a bit more before the radial pressure-bearing part of the case is no longer supported by the barrel.

Apparently, on the 1st generation FN PS90, you can move the "tail" of the trigger return spring just a tiny bit and this happens...

At this time 25 years ago, I was milling around the house, getting breakfast, and thinking about my upcoming prairie dog murd3ring trip to Wyoming later in the week. In a little while I'd be turning on the TV to check out the weather for Medicine Bow, Wyoming, because the internet wasn't quite there yet, and that's how we did it. A little before 9:00 I turned on the TV and was shocked at what I saw; a plane had "accidentally" flown into one of the twin towers and smoke was pouring out of the giant hole in the side of the building. I probably hadn't been watching 5 minutes when I saw a jetliner fly into the second tower, and at that moment I knew that this was no accident. I had an idea that the world was about to change, but had no clue to the extent of it. First and foremost, the immediate cessation of air travel meant that a few hundred prairie dogs missed a meeting with my heavily customized AR-15, and got to live out their puny lives instead. We were allowed to fly again after a few days, but it was awful. Seeing soldiers in airports with M-16s was sort of cool, but the long waits and near strip-searches were not cool at all. Years before, I accidentally took a flight with an entire 50-round box of .22LR in my pocket, and now you couldn't get on a plane with a nail clipper! The terrorists who planned and executed this horrific act that claimed the lives of nearly 3,000 innocent people, put a resolve into our nation that probably hadn't existed since Dec. 7, 1941...we were going to get the bastards who were responsible for this! In spite of how awful it was to travel by plane for the next couple of years, it was a nice time in the U.S. It seemed that our petty differences no longer mattered against the backdrop of a shadowy terror network that would, no doubt, strike again soon. We felt like a united country for a while, and I'm glad to have lived through it. A quarter century later we've done a lot and learned a lot, and things are currently pretty quiet on the terror front. We lost a lot of freedoms that are mostly back, and it's kind of nice to be trusted to fly with a nail clipper again. It's also nice to know that if some bastards ever try to take over an airliner with box cutters again, there'll be a competition between passengers to decide who gets to beat the perpetrators to d3ath. Rest in peace to the 2,606 people lost when the twin towers collapsed, and for the rest of us let's move forward, mindful of how lucky we are not to have met a similar tragedy.

Most of our parts get professionally heat treated, but we usually do prototype stuff in-house. The alloy steels we use are heat treated somewhere under 1,600 degrees F, but these tool steel pieces I'm doing for a buddy went to 1,800. Definitely brighter than what I'm used to!

About a quarter century ago, we'd test-fire every BFG-50 bolt and barrel combination in this text fixture, then magnetic particle inspect them. The fixture was known as the S.L.U.T. Anyone remember what that acronym stands for?

It stands for "Serbu Low-mount Universal Tester. Kind of a stretch, but it was all about using that acronym!

Fuzzhead and I test-fired the Diabolus rifle at a local range the other day. It did very well, with just a few hiccups that are to be expected with a prototype. Everyone who sees and handles this gun likes it, and I think it's going to be a bit hit once we start shipping 'em!

FINALLY did the first welding at the new shop. These are BFG-50 bolts, and there's a deep V-groove that gets filled up with TIG weld. The plug weld is where the 3/16" stainless (austenitic) pin locates the bolt head to the bolt body. After that the area is turned down on a CNC lathe.

Anyone have a source for AR-15 rear takedown pins? Our usual suppliers seem to be out.
