[ARCHIVED THREAD] - Mk 19 (Page 1 of 2)

Can you fire a Mk 19 grenade through an M203? And if you could, would it hurt you?

Quoted: they both shoot a 40mm grenade. I'm pretty sure they both can fire the same rounds. I believe I read somewhere that the M203 grenade has a maximum range of ~400 meters, while the Mk19 has a maximum range of something like 1500 meters. That alone tells me that pressures are radically different between these two rounds. |

That must mean they are both interchangeable  The guy at the gun store told me thats why he picked up an AK when he was in the LRP Delta Recon Seals. Because they shoot AK, M14, and M16 ammo.

I'm more interested in knowing if that particular weapons system is really effective in the current theaters of combat, and if so, how, exactly? MK 19 rocks, Bad dudes in house, hurray 40mm explodes in house Bad dudes in car, hurray 40mm explodes on car It jams a bunch, but oh well, it makes things explode. |

Quoted: they both shoot a 40mm grenade. I'm pretty sure they both can fire the same rounds. This would be wrong. You can fire a M203 round from a MK19, but not the other way around. if you did, there would be some serious issues. The pressure would cause the tube of the M203 to explode into umpteen pieces, therby shredding your hands, and upper torso. Now in an extreme conditions, if needed you could chamber a M203 round in the MK19. it is not recommended, but will work. |

You can put 10-12 rounds at a time into a 55 gallon drum at 1200-1500 meters. It is very effective at getting the enemy to break cover, and therefore be open targets. As mentioned, you can slam a round thru a house window 1500 meters out. Weapon placed on an LP/OP weapon position, and vehicle starts to run checkpoint, Goodbye!!! As for the jamming, it is meant to run WET (Very sloppy), and most want to shoot 6-8 round burts. It is actually designed to shoot 10-12 round burts. Short bursting it will cause it to jam. |

The mk19 was made for the jungles of vietnam and Jungle patrol boats...the entire inside is chromed so it can run completely dry if needed. But it never does, because it jams constantly unless lubed up. |

But we are on the Mod 3s now, I know when the team from Benning came to teach us with our total fielding for desert storm, that was one of the issues they had, and the corrective action was to run it very wet. Because of the sandy conditions. it worked. Yes we still had jams, just like any other weapon, but running very wet seemed to help. I know last couple of tours, we enforced the daily cleaning/lubing, and seemed to have less issues. Granted they are not getting fired as much as a whole, but they still got a workout. |

The answer has already been provided, but was this question really worth asking?
Seriously, look at the 203, there really isn't any structural material on the reciever (hence the "low pressure" round) Look at the MK 19, the thing is made of large gobs of steel, it screams big and beefy (i.e. can handle high pressure load) Please don't ever try to swap one 40mm round for another, you'll only do it once. |

It is very effective, but like any weapon system it depends on the terrain of the area your operating in. It is fairly ineffective in Cities (not to mention were trying to fix stuff not blow it up) The reason for ineffectiveness is that in most areas the round will fail to make it to its minimum safe arming distance before it strikes a building. However there are areas where it can be effective in the city, again it depends on terrain. It is very effective in Open areas, especially where the enemy may be massed, or may be in defilade.
40mm Grenades are extremely effective against light or unarmored vechiles, they are also good against enemies who are protected by terrain from direct fire weapon systems, and it also does a great job of breaking up a massed attack. Typical uses would include mounted on a guard tower or other defensive position at a fixed site, or if your operating alot in open country it would also be effective. So to answer your question, yes it still is a relevant weapon system, and it all comes down to the commander on the ground to employ the correct weapon systems at his disposal based on terrain and the enemy threat he is facing. |

I never had that issue when I gunned one. Have you gunned one on an operational basis or just in a range environment? The MK 19 is by a big margin the most finicky of vehicle mounted crew served weapons, and it requires more, and better quality maintenance than the other typical turret mounted weapons (M2 and M240). Dirt and improper lubrication are a big culprit. Although you will often hear the advice to "run it wet", the Mk19 is not a CLP weapon, it has very specific lubrication requirements and spraying an assload of CLP into the works is not the answer. Another source of trouble, that is not often recognized is ammo. Cans of MK19 ammo that have been bounced around in gun trucks, been loaded and unloaded from vehicles and generally abused under field conditions can have fucked up links, that even though they look okay are sufficiently out of spec to cause jams. To a big extent the same applies to the gun as it's ammo, it just won't sustain the same of level of hard use conditions that a good .50 or most 240s can soak up with no trouble. MK 19 is a good system that brings a lot of firepower to the fight, but it does fail more often than the other systems, thats just a fact. |

I can't speak for other parts of Iraq, or Afghanistan, but where I am we don't run MK 19's in the turret any more, mostly due to the fact that if you cut loose with one, your gonna kill/destroy alot of people/stuff and our area is heavily populated, we do keep them in some guard towers and in defensive positions on certain JSS's just in case someone decides to try and force there way into a JSS/FOB They are finicky and like to be run very wet, but when there working they bring one hell of a punch to the fight. I shot them on a big range back home, and I had about 10-15 grenades in the air before the first one hit the tank hulk 1200 meters out.

We have the UGWS mod mk19s, no spade grips, has a spot for an electric solenoid. |

the MK19 is a poor design. the part most critical for its' function, is also the part that is most difficult to manufacture, most difficult to maintain, and subject to the most abuse in the gun. there are microfinish requirements on that same part that have no business whatsoever being in any weapon meant to be fielded in a combat environment, and the gun won't run unless they are met. |

Just out of curiosity, for the folks talking about running them "Wet"...what does that mean?
I've shot a fair number of rounds through them in training environments (Where they seem to dirty-up quicker than shit) but my unit is heading to Afghanistan in a couple of months and inquiring minds would like to know what you guys are running them "Wet" with? BTW.., we're taking shit loads of LSA-T and LSA but that may change to GMD (Easier to find) if we can't get the other two. |

you should see what they do to a T72. Scratch the paint? I was terribly disapointed with this weapon system......would take a .50 any day of the week. And that would only scratch the paint on a tank as well. BTR/BMP OK, still would rather engage with the Ma Deuce. Sorry M1A1 guy who would have NO fear if being fired upon in ANY modern main battle tank by a puny little over rated 40mm grenade. And yes I have seen the grunts spray down buildings in Iraq with these things hence my opinion. Might be impressive for you crunchies but certainly nothing special from an armor point of view. |
