@@petermuller3995 I'm not really sure why this is funny...do tell.

@@MarcJaxon I think some people are worried that Mr Serbu will go "Right, checked it all out, gun was fine, very strong, definitely dodgy ammo!" and then scrap the bits. I'm not saying he'd do that and I honestly don't think he's that kind of person but that's what some people are concerned about. Like when the police investigate themselves.

@@Stigstigster and I get that. It is a rational concern. But I wasn't trying to suggest that Mark will be all alone in his creepy little design dungeon laughing maniacally while trying to formulate an "out" to save his ass.

The SLAP cartridge was designed for the Marine Corps to use in tank machine guns. It is not permitted to be fired through the M107 due to "hazards". This cartridge is dangerous to fire from anything other than a M2. I do not understand why nobody is talking about this. It needs to be said that people should not put SLAP cartridges into their rifles.

They're just hyping up the trend and making easy money with their lame excuses. You should be ashamed for disrespecting Christianity and the life of innocent who will lose their lives because of a failed design of a man who should be arrested. You will make the left win this war.

@@suprememasteroftheuniverse what in the fuck are you on? The RN50 is safe for normal ammunition, 55kpsi. .50bmg proof loads are 65kpsi, and every RN50 shipped is tested with one, by Mark Serbu himself, with his shoulder behind the gun so if it were to blow up Mark Serbu would be dead. The threads stripping off the cap that make the round that blew up KB's gun _at least_ 85kpsi, if not more. While there most definitely is someone at fault for this, it's not Serbu.

It was ......that rifle worked perfectly fine

@@CHOPMOP10 other than not having a design that if/when it fails doesnt send shrapnel and a 2 lb cap right into your face/neck area... its perfect.

@@memeier9894 That's pretty much a possibility with EVERY design. A high enough over pressure event can easily turn the bolt into a projectile and/or shrapnelize the gun.

@@reaperreaper5098 with enough pressure sure, but a given volume can only produce so much pressure, and it should be designed in such a way that even if it fails catastrophically, it should do so in a manner that does the least amount of harm possible. In my opinion two little locking ears whizzing past your head and an end cap hitting you in the eye at mach 5 isn't it... I don't blame the rifle for failing, the ammo in my opinion is the culprit, but I do fault the manufacturer for the way in which it was designed or not designed to fail in.

Scott successfully shot an API round just prior to the accident, so I can't see any likely way there could have been a barrel obstruction when he took the last shot.

Imagine deciding you should talk to a physicist after you design and build a firearm.

@me Me they were surplus rounds. Why do you have to go around spouting off information that’s not correct. You’re assuming a lot....

@@Freakingstang They were sold as surplus rounds, who knows if they had been modified or reloaded or how old they were.

You're lying to defend a criminal who should get life in prison. You're Serbu's accomplices and also deserve to be arrested. The KZfaq gun community is a completely shame shamelessly jumping in this trend to make easy money making up excuses. Scott used a slap round. He's guilty. Serbu's guilty of his failed totally unsafe design. He said in a video that 50% was not enough safety and would like two or three times pressure resistance. Also Scott told him what kind of ammunition he would use and Serbu sent him a modified rn50. I hope he ends up in jail and all these channels are banned. You instead of saying the truth are trying to hide behind lies to not lose your fake jobs on KZfaq. That's absurd and unmanly. The left will win the war against gun rights and gun channels will finally be banned. Congratulations. Sadly leftists were right about most you in the end.

@@suprememasteroftheuniverse you're grasping so hard at straws that don't exist.

The sabot obstruction was covered in this video as unlikely.

@@suprememasteroftheuniverse Dude, you're insane. Sincerely, a socialist.

It was explained at 4:44 that it would not blow the cap off.

A fail safe 50BMG have you any idea how much that would weight ?

@@septicwhelk3654 Adding emergency gas vents shouldn't add to the weight, if anything it might slightly reduce it.

@@septicwhelk3654 Serbu himself makes a 50 with an enclosed receiver that probably would have failed in a more safe way. Not zero risk of course, but probably less stuff hitting the shooter.

Threads are still more vulnerable to wear and damage from constant use. Cross threading can damage the first thread and grit can gradually erode. You don't unscrew and rescrew your barrel each time you fire. Suppressors for example have been moving to lugged quick connect systems away from threads partly for this issue.

@@ctrlaltdebug yes that's true about not unscrewing your barrel, still think it proves the base concept. Cross threading? You're doing it all by hand.. to cross thread it and cause serious damage you're going to have to ignore lots of warning and use alot of force to cause serious damage on threads that size. obviously if the threads become damaged that changes things.. Just like if a barrel extension or bolt lug becomes damaged in any other design.. sure there's wear on the threads just from normal use, but it's also a single shot .50, not something people are generally putting thousands of rounds through a year, especially not the person that bought the lowest cost .50 on the market. Threading on the end of most firearm nuzzles are alot smaller and would be more prone to damage or cross threading. Also, tri lug mount suppressors or accessories in general have been around for at least like 40 years, if there was such inherent issues with direct thread cans I'd think they'd be alot further along in phasing it out by now. The main advantage I think most people see from lugged or quick connect type cans is obviously the speed of taking them on and off but also not having to worrying about them walking off.

It's different with the barrel because the cartridge is in the barrel (or chamber) the chamber expands as the cartridge ignites tightening the barrel in the receiver making the joint more secure, plus the barrel is torqued into the receiver to begin with, not so with the breach cap on the firearm in question.

But it’s literally not. As correctly stated in the video it’s not that threads aren’t sufficient it’s that the placement of threads needs to be correct.

I don't know the metric conversion, but in imperial units it's approximately 1 fuckton ± 1 shitload.

@@mattmurphy7030 Check any reloading manual and you'll see that there's a world of difference between a "normal looking" cartridge and a "normal acting" cartridge. Throw pistol powder into a .50 BMG case for example, and I defy you to find a gun that WOULDN'T explode from attempting to fire it. The difference between a cartridge and a grenade comes down to some fairly tiny details that an inattentive or inexperienced reloader can easily fuck up. There's a common warning in the reloading community that you should never, under any circumstances, fire a cartridge unless it came A: directly from an ammunition factory, or B: from your own reloading bench. I don't want to blame Scott for what happened, but if you make a habit of firing oddball rounds that you bought from "some guy," there's a good chance one of your guns will eventually blow up in your hands.

@@mattmurphy7030 I'm honestly not sure where else the shrapnel was supposed to go. Your face is right next to a gun when it fires, and if all that pressure can't go forward then "backward" is pretty much the only option left. I suppose the top of the chamber could be designed as the weakest point, but that would probably cause its own safety issues

I think Serbu mentioned it was estimated they can hold 20k psi of pressure together before shearing off like that

I said this in Serbu's video that they should make them longer so if something like this happens it won't shear them off like that.

Well, according to the formula that's used to determine psi load bearing limitations in relation to thread diameter, pitch, angle, and depth, the load bearing limit is 160000 psi. So, by knowing the average pressure produced by a standard .50 cal round, its suffice to say that Serbu's design is rated at almost 3 times higher than what standard . 50cal rounds produce. I'm not sure if any firearm made could withstand that much overpressure. 160,000 pounds per square inch is just such an insane amount of pressure and is almost impossible to even fathom just how much that is!

Yeah I mean if you got money to buy a .50bmg rifle why not get either the bfg50 or the one I'd prefer which is the Armalite AR50? They're like a thousand bucks more which is a hell of a lot less than any hospital bill!

Done right, interrupted threads can also serve as gas vent holes pointing in a safe direction. When in the locked position, the milled-away portion of the threads line up to form wide open channels forward. Make these line up with relief cuts on the barrel so any leaked gas can safely vent forward away from the shooter, and Bob's year auntie. Of course, interrupted threads have less engagement area so you need a longer thread section for the same strength. Also, unlike a simple threaded cap these would need careful fitting so they close up with full engagement at the correct headspace, the current design is self headspacing and automatically corrects for wear or ammo variables by always screwing down to zero headspace. Thus, going to interrupted threads would increase cost and possibly reduce accuracy.

@@Kaboomf If I recall correctly what Mark Serbu said about why he didn't use interrupted threads, the two main issues were machining the threads themselves (apparently much more difficult than it seems), and more importantly adding an effective out-of-battery safety.

That's blasphemy. You should have more respect.

That would be a lot more expensive and I'm sure the rifle is designed the way it is to be cheap for a .50

@@Phoenix_Atlas it would not be that much more expensive. All it would really do for that type of breech is add a couple more turning operations on the lathe and maybe another milling operation. Besides, I think it would be worth the extra $200-300 per gun to incorporate that kind of safety measure, especially after having such a public display of the inherent weakness of the screw on breech.

Just use good ammo. It would require irresponsibly over pressured rounds to have it fail. That said, do what makes you feel comfortable, no one can blame you for that.

@@sinisterthoughts2896 That is what Blaser claims. However, I personally know a guy with failed lugs. He only managed to fire a few factory loads before they let go.

That is not hard

LOL, Arky here and I am ashamed that I have to agree.

@@stevebettany8778 All you have to do is not say LIKE every other word.....

That might be a possibility, these factors would certainly contribute, making it more likely to fail. but it also depends on the chamber dimensions and headspace of that particular firearm because these factors determine how and where would the brass case stretch and flow.

Biggest problem by far is gun did not fail safe

Plus very old rounds that are available only between others private owners and not reliable sellers

WHAAAT, you mean to say that I can't load a 1oz slug in a 12 guage, use as much pistol powder that will fit in the shell, and shoot it safely? What kind of world do we live in.
