The ASG LRMP Module Gen 1 system was a big hit, but I’m always trying to improve. So without further ado… ASG LRMP Module System Gen 2 (Pat. Pend.) FOR CENTERFIRE CAPABLE ACTIONS ONLY. If you're looking for LRMP for a 700ML go here: dougsmessageboards.proboards.com/thread/19828/700ml-lrmpFirst off, any builds in progress will automatically get this new plug. For anyone currently using the gen1 system, this head-spaces out the same and uses the same modules as gen1. However, insert ID is a little different then the gen 1 system, so will require a module refresh too if you want to switch over. Instead of seating bushing from front of plug, I realized that things could be done in reverse. Additionally, the bushing is now effectively at the end of the module resulting in a very short flame path. To my knowledge, it’s the shortest flame path available on the market. Compared to the gen 1 version, it yields higher velocity and lower ES. Here’s a picture of both ends of the plug. No more exposed threads. Internal threads.   Here’s a close-up of the plug showing the bushing retention insert.  Here’s a close-up of a plug with 100+ shots on it. Cleaning the flame channel is no longer required because the flame channel is completely contained in the module. Effectively, the flame channel is self-cleaned every shot with the removal of the module. The insert is epoxied in place, so bushing removal may not be possible. However, with the tiny flame channel volume, bushing wear is almost non-existent.  For reference, here’s a picture of what the modules look like.  |

I'm not trying to be negative about what you're doing I think it's great you're trying to go forward.
So if I understand this you're putting the tungsten bushing in the front of the plug and then gluing it in with the sleeve? To make it simple understand.
If that is the case what happens if someone double loads or bushing or glue failure does that not push everything back towards the shooter?

If that is the case what happens if someone double loads or bushing or glue failure does that not push everything back towards the shooter? Good question, but No... the insert is threaded in place. The epoxy is prevent gas leaking around the insert. There's actually more metal supporting the bushing then other LRMP systems on the market. If the bushing were to let loose, it would probably just push into the module. While it probably wouldn't be a pleasant experience, shouldn't be any different then a CF case head separation. |

What about non lug gun? I guess I will have to cut the threads off a breech plug until it pushes out the back of barrel of the test my action strength?😀 Time to blow one up💥 |

I guess I will have to cut the threads off a breech plug until it pushes out the back of barrel of the test my action strength?😀 Time to blow one up💥 That's an easy answer... these aren't for non-lugged guns. |

This looks awesome!! Have you measured the flame path distance from primer to powder? From what I've read with 250 grain bullets your on the lighter side of ignition problem people have miss fires with 250 and lighter bullets with straight powder. Do you feel this could fix this issue with shorter flame path?
Thanks for the update!

Lukes new system works great with 250gr bullets. |

Lol 🤔. Thanks that's for the help Omega. |

Lukes new system works great with 250gr bullets. I have an ASG LRP module system on a Scout conversion....I think it's a definite step up from 209 system.... To answer the question in regards to the 250 gn bullets...I have had two misfires in the first 50 shots using straight H4198 and 250 FTX's wool wads at 30*..This is personal experience not internet speculation...Even so I like the LRP system better....This new gen system might be the answer...Until one comes my way I'll be adding a little 4759 to the 4198 just to make sure...Especially when it's cold outside |

Luke....
Could you explain this module refresh a little more.....

Zen Zen, The modules are very depent on tight fit to "chamber" walls. So if there's any variation in size, they will leak. Especially going smaller to bigger. The Gen1 necks down a little more at the end. Now that I think about it. You could probably "resize" the nipple back up to create the brand new module effect. Hope this makes sense. Luke |

Luke The reason I was asking is that I was thinking about getting an extra LRP plug for the Remington 700 I just built....If I went with your new plug do you suggest that I should get get new modules that are specific for the new plug or can I make the ones I have now work...Not sure what you mean about resize the original modules back up...Or how to... After thinking about it I think I get what you mean about the resize....I wonder if you could fire form the originals to fit the new plug. Zen |

Zen I'm not exactly sure how you would do it too as I haven't bothered messing around with it. Fireforming might work. Or maybe using the punch shank like an expander ball at the end of the module to open it back up. |

Anyone out there have a couple hundred shots on this new design in a subcal with large doses(100+gr) of a slow burning powder? Any bushing wear?

I do have a 100+ shots with this new plug in my 45.... All the shots have been in the 47-50k range with 300gn bullets....I'm finding an increase in velocity 40-50fps over the original LRP plug with single digit ES.... So far My bushing hasn't shown any signs of wear.... I also put 25 shots through it with 75gn 4198 and 250gn TEZ's. It shot well also.Might be the ticket when it comes to straight powder loads and lighter bullets. So far I'm liking it. Zen |

I'm approaching 200 shots on my current bushing. And it's still sitting at .035. It's possible the front is starting to "trumpet," but really no way to look at it.

So is everyone liking the gen 2 plug ? Anyone ran into bushing wear problems ?

From what I read if bushing wears out the plug must be replaced .. am I right ?

From what I read if bushing wears out the plug must be replaced .. am I right ? Yes... but the bushing doesn't wear out. I have 900+ rounds thru mine. The .035 wire just started to pass. The .037 wire will not start. I bought a new plug just in case. I shot 25 or so thru the new plug and no change in velocity was observed. Reinstall original and will keep using it until performance is affected. |

Okay I can't see any of the pictures so Let me no if I have anything wrong ..
the bushing is inserted and epoxied in but also has a locking screw ?
so you drop bushing in, it sits on a shoulder inside of breech and you install locking screw from the module end ?
With this setup doesn't all the pressure come back to the locking screw threads keeping bushing from blowing out the back of plug?
Which would be the reason this plug is strictly for center fire action.
Anyone using the gen 2 in a break action ?

The second sentence of the first post is pretty clear, that the Gen 2 plug if for centerfire actions only.

Yes, Luke has an option that converts break actions to use a LRMP Breech Plug.

This thread is introducing the Gen 2 LRMP plug. This plug is for centerfire only.
Yes he does make other plugs for hingers. Not Gen 2.

I have to correct myself. I have the Gen 1 plug.

He shows nothing but Gen2 for the LRMP, including a 4570 option. Also, most break actions are centerfire action. They do fit into that 2nd sentence in his offering of these plugs. I do not own one of these so I am sorry for the confusion if I was incorrect in my assumptions. |
