Improve durability and longevity of AR internals. 2. Automatic adjust internal gas pressure when equiped with sound suppressor 3. Automatic adjust internal gas pressure when chambered with ammo of different brands 4. Completely disabling gas pressure by removing PSV internal (i.e. springs groups and main seal..etc) 5. Simple and durably design 6. Interchangable spring groups for different barrel lengths (i.e. 7.5", 10.5", 12.5", 14.5" and 16"..etc) 7. Decrease the possibility of receiver explosion or catastrophic failure as a result of extreme gas pressure. |

This is designed as a drop-in kit for existing DI AR's. This kit would comes with two favors. A2 style front sight with built-in PSV, or rail gas block with built-in PSV.
The existing standard Gas blocks are basically a block of solid metal (with internal gas channel). I thought we could introduce a little complexity to turn it into a auto-adaptable gas block. |

i dislike things that add more moving parts to my AR's.
your next invention should make the system more simple... not more complex. |

One problem I see is with that tube sticking off the side it may get in the way of various accessories - flashlight, canted sight, etc
Cool idea though! |

I was thinking this my self but don't you think the gas going through it would blow everything out? I still don't need one, even if they do work. It just seems like something else that could fail for a gun that if built right won't. |

The PSV could be placed at the bottom, or the other side of a gas block. This drop-in kit offers several options for buyers to get their desired orientation. |

The AR-15's already a self regulating system. Also, for all the carbon fiber and machined titanium your plans show, it would probably cost more to purchase than a piston retro-fit kit.
"7. Decrease the possibility of receiver explosion or catastrophic failure as a result of extreme gas pressure." I'm not saying that can't happen, But I HIGHLY doubt that a round could leave the case, make it most of the way down the barrel past the gas tube, THEN have the gas travel back to the bolt carrier group with enough pressure to cause a catastrophic failure, instead of blowing up in the chamber in the first place. |

i may not kno much about anything, but i dont think the receivers explode because of excess gas going threw the gas tube...they explode when the case fails...

I am trying to increase a rifle functional values by introducing a little complexity. i still am not seeing a functional value increase here. is this going to make my already perfectly functioning rifle function better? all i see is more things to go wrong. haven't you ever heard of "the less steps in a plan the less likely it is to fail"? |

1. Improve durability and longevity of AR internals.
2. Automatic adjust internal gas pressure when equiped with sound suppressor 3. Automatic adjust internal gas pressure when chambered with ammo of different brands 4. Completely disabling gas pressure by removing PSV internal (i.e. springs groups and main seal..etc) Noveske Switchblocks I take one step further and convert a gas block into auto-adoptable gas block for sound suppressors and for ammo of different brands. |

Basically, you're taking the front half of a gas piston system, which has been fine for decades using regular steel, and turning it into a vent that hangs off the side of the gas block right?
Who knows, it might work fine. Or, you might have to put so much spring weight on it to make the rifle cycle reliably, instead of venting all the gas that it's not worth having on. |

Have you fabricated a fully functional prototype yet, or is this all theoretical at this point?
I'm not sure that I see an industry need for this, but good on you for taking the initiative to build a better mousetrap I guess Posted Via AR15.Com Mobile |

I mean.. i really am impressed by your understanding of mechanics from a complexity stand point.. but EVERY thing you come up with makes the system more complex. possibly you should try designing a complete new firearm system with your ideas instead of trying to shoehorn tons of small parts into a proven system? |

The user can reach into their pocket, pull out an end wrench, remove the cap, pull out the parts, insert a carbon scraper and clean the thing? You're adding more parts, more moving parts, additional maintenance, and additional reliability issues. And when this gadget quits working, the user will have to perform a transition drill, while making double sure the extra hot thing sticking out the side doesn't burn them. |

It's an expensive pop off valve.
If anything, scale it up and market it to tuners for guys running turbos as blow off valve. |

Interesting, but as some others have commented, your idea makes AR15s heavier and more complicated.
I bet they would sell like crazy! |

How does it react to water? How well does it drain if the weapon is submerged? Posted Via AR15.Com Mobile |

Its not the guy that walks in with a gun and says he is going to start shooting that you have to worry about.
Its the guy that just walks in and just starts shooting. |

i applaud you on your technical incite to this issue. however, without a supressor, there is no need for this device. i have fired many different brands of 223, and 5.56 ammo through mine without failure. the rifles like one better than the other though, but it has nothing to do with the amount of pressure to the carrier key. i am not at all knocking your design as it looks like a worthy piece of equipment, and obviously well thought out. with skills such as yours, you should try your hand at a new platform for this piece to integrate into.

Didn't know there was a problem. Why is someone always trying to make a simple system more complex?
So many solutions, so few problems. |

I knew it.
Seen this guy's posts on two other forums, and they were all something like this: "What do you think of this rifle configuration?" followed by a list of parts that would change daily, each time in a new thread. I really don't understand the point of this product, you couldn't even give me one to T&E for free. My lonely little gas tube does fine on it's own. Next time you're going to post a bunch of bogus threads all over the internet, do us all a favor and just be upfront about your intentions. |
