- I screwed up and the position of my camera at one point gets my breathing, which will probably be somewhat annoying, Unfortunately I didn't notice until the grenade was back together, so I couldn't re-film it.
As the Title says this is an explanation of the Russian RGO grenade which is both an Impact, and delay functioning grenade.

I've wondered for years how this worked, this was an incredibly informative video incredible 👏
Glad you enjoyed it. Thanks for watching.
Forget visiting a museum, I want to visit Stray's garage!
Lol it's a mess and not overly exciting.
I like the string safety on the 247 a little better for the simplicity, but that one is damn clever.
Good thing about it is that it still has a delay, even if the impact doesn't set it off, eventually it will still go off, the 247 wont.
@@Stray03 i always thought a spoon fuse could be used to good effect with one of those ball strikers to achieve a destruction delay, but in my head the spoon would pull the stop away from the ball striker mechanism on release, but that wouldn't be safe with the "tree branch short-stop" scenario like this one would hopefully be.
Oh, shuks, I suuuuuuuuuuuuuuuuure want one...... where on earth did you find such ? Since I cant own one, I'm just lovin' yer videos!
The ball is made of epoxy and small led balls so it will disintegrate and not become a projectile that will fly far and anywhere...., a problem with the lead balls in the British Always Fuzes (M-69?) as used on the Gammon Grenade.
Thank you!
Got lucky and was at the right place at the right time. Been looking for one for a while, saw this didn't even try to bargain. Yeah the ball idea makes sense, just don't know why they would use it on a grenade that already is designed to throw shrapnel. Maybe it is just lighter than a full lead ball?
@@Stray03 I’m a structural Engineer… not a mechanical… so I don’t know what that is worth but it is true that the M67 will sometimes throw off “big” chunks of shrapnel. This might seem like a great design concept. But offensive and defensive grenades are built differently for different reasons. Ideally when you throw the grenade out into an open field… throw it as far as the average Marine Infantryman can throw (which is measured and known). You want the fragments the grenade produces to only kill the enemy. But that being said… big or small pellets… if one hits you… it’s not going to be a good day. I tend to agree that it might also be a design choice based on “weight or mass distribution” of the epoxy blob for some reason. Or economics and other design considerations combined. Maybe they needed the mass but couldn’t tolerate an exposed metal that might corrode during some period of the designed service life.
@@Stray03 Why would there be three ball bearings of that size and not one? Unless you could vary the amount of mass for a more “sensitive” fuse. Or as stated. To give any possible fragment produced a uniform consistent size. The plastic will be turned into a gas (vaporized). It’s an interesting puzzle. Chip… why did you say what you said? Was it an educated Guess? Or is there some documentation that is indeed why the design is as it is? Just curious.
It is basically shot in a resin. Maybe since there is a big hole in the top of the body they replace a solid ball with many small bearings or lead shot which ever it is to as you say give multiple fragments (like how the claymore holds its schrspnel together) and increase possibility of hitting a target. 1 ball vs birdshot basically.
@@Stray03
I admire your luck!!!
As you most likely know there is the defensive frag version and the offensive blast models, the fuze is the same on both I would assume., The Britts were worried about the lead ball in their Allways fuze to 100 yards or more.
Bravo.
Thanks. How is life treating you?
@@Stray03 Fine my friend another day older and deeper in debt. The American dream. Be safe hope all is well. 👌👌💪🏻💪🏻💪🏻💪🏻
All is well. Yeah with our politicians wasting our money it is a surprise we are not worse off than we already are.
@@Stray03 They sure know how to blow it up a hogs ass. My property taxes just doubled. I think it’s time to put some hard working common men in control of the country. People that live in the real world not a bubble. But as my old man use to say. Son wish in one hand and 💩in the other and see which one fills up first. Power and greed old as time it’s self. Stay safe. Stay cocked and locked and most of all get right with GOD. There’s a storm coming.
Why are fuses such complicated devices
Usually safety plays a big part of it.
Good video as usual. Hope you're doing well.
Thanks. Yeah I'm doing OK. How about you?
I'm interested in how they affixed the 'four sphere segments.' It looks like the female threads at least, are aluminiyum. I am guessing the outer segments are steel, the inner al?
Threaded insert is aluminum rest seems to be steel. Possibly pressed and epoxied? Can't see enough of the inside to tell. Maybe they mean 4 parts together and the info over time has been corrupted.
@@Stray03 Every video of my brother is a high-quality product. I hope that I can have a good time with you in my lifetime, shoot guns together, and play the things you explained in detail.
@@Stray03 I will watch each of your videos seriously and repeatedly, hoping to find inspiration for making them. My biggest wish now is to immigrate with my family to a country where you can freely play with guns
Hay haven't heard from you in awhile. Hope all is well.
All is good. Life is keeping me busy, And you?
You ever go back and check on that horse burial? Bee cool to see what it’s like now
Went back the year after and sadly saw nothing. May try again this year.
@@Stray03 If one horseshoe is good luck four horseshoes should set you up for a lifetime of good fortune.
Lol definitely should have. Less lucky for the horse though.
@@Stray03 Yeah but he wasn’t using them anymore… I bet he wouldn’t have minded.
Animals love to chew the bone to get the vitamins.
I know yt will never boost you despite you not having an ideology about using this stuff but you're still valuable 😃 👍
How did this plastic Rube-Goldberg device handle temperature swings? Did they crack or shrink till they'd stick or anything like that?
And can water penetrate and freeze inside?
I don't have any info on temperature but I assume it follows the standard you would see on similar items. The plastic as you see gets weaker after time so it will Crack once it gets old enough or is improperly stored. While not cracked the whole thing is sealed so unless there was a flaw in it, there is no way for water to get into the fuze mechanism.
have you seen valgears video on this grenade? hes a Ukrainian soldier and has access to the real deal, knows his stuff
Just watched it, unfortunately when you have live ammo you don't take it apart to see how it works inside. Shares good info though which is nice.
You still with us.
Yeah just busy with life and projects. How are you?
@@Stray03 Hanging in there.
No thanks… Soviet Engineering… complex… grenade… no, no, no, no. I didn’t even like carry the M67 and that’s a tried and true design.
Lol. Yeah although the 67 is pretty well made quality wise there is still the chance of having a Crack in the delay train making it shorter or non existent. This thing has 3 with for sure much less QC and with less care for the soldier too.
@@Stray03 When we would go to the Grenade Range (approximately once or twice a year). The entire Company would get to throw a live grenade (M67) after PowerPoints and safety briefs and throwing training grenades. There was a special concrete tower with bulletproof glass you could climb and watch the frags explode and the pits where you would throw. I also was awarded a NAM (Navy and Marine Corps Achievement Medal) for killing a man pinned down in rubble with an M67. I set the grenade directly on part of his exposed body once we unburied some of him. That design would be worthless for anything but throwing away from you as far as possible. I know and trust the M67. Never had a “dud”/bad fuse that I can remember. That Soviet concept of an “instant detonation” with a fale safe delay does have advantages but also limitations. In Iraq we would throw the frag as hard into a building as you could and you could “bounce” the grenade off a concrete wall into an unseen room. If you are dropping a grenade through a pipe in a bunker or building roof… it might hit the side of the pipe as it falls… what if you throw it in the woods and it hits a tree branch above you? “pressure detonation” sounds scary. As a Marine Infantryman who was sent to the Marine equivalent of “Sapper School” I loved explosives but fragmentation grenades always terrified me. You’re carrying instant death on your person for months. HARD months with no cleaning and crawling over walls and through brush and low crawling… the frags get “beat up” really bad. Plastics? Soviet plastics? Complex fiddlly design that could result in instant death… Ughhh no. No. No. No thanks. And YOU ARE WEARING IT LIKE JEWELRY… I have a “love and hate” relationship… with the devices.
Hope all is well.
Yup, just busy as usual. How about you?
@@Stray03 Good sir glad all is well. 👍👍
@crawwwfishh3284 yup just busy as usual. Glad you are doing well also.
Where’s you find it? I may be mistaken with my RUclipsrs but aren’t you from Canada?
Company with military surplus once in a while has one offs they sell. So right place at the right time is usually how these things happen for me.
@@Stray03 pretty friggin cool man! I’ve run into a lot of issues when looking for inert ordnance, most us companies won’t sell internationally and I can’t find any domestic sources for my collection when I do it’s overpriced and auctions. When you buy stuff is it from an international supplier?
I buy stuff in country because I never know what the border guys will decide is allowed or not depending on their mood that day. To avoid losing money I just spend a bit more on stuff already in Canada.
so u could roll this in to a fire for random cooking too then
Is this item for sale??
No. Sorry.
Please make a video on real m67 frag grenade
Real and dummy ones are almost exactly the same. The inside of a real one has the texture put into it but the 213 fuze does the exact same thing.
