  1. I take that as an encouragement.
  2. I agree with your assessment. I have been thinking ways of improving it.
  3. Do you think this concept would work?
  4. Close Up Diagram Cross-section Diagram The total upward pressure of a fully loaded magazine is equally distributed between the top first round and the pressure damper. The total amount of upward pressure of 40 rounds, divided by 2 should be less than the total amount of upward pressure exerted by a 30 rounds magazine.
  5. 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.
  6. Pressure Relief Valve (PSV) for standard Direct Impingement AR's. Standard Gas Block with integrated PSV Disassembly Diagram Belleville Springs Washers Reference (explaining the strength of spring washers) https://docs.google.com/viewer?a=v&pid=...Qy&hl=en_US Design and Animation (created by Google Sketchup8 Free Edition) https://docs.google.com/leaf?id=0B9XSnDKMwp...Ux&hl=en_US Features and Advantages 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) 5. Simple and durably design 6. Interchangeable spring groups for different barrel lengths (i.e. 7.5", 10.5", 12.5", 14.5" and 16"..etc) 7. Decrease the possibility of catastrophic failure or receiver explosion as a result of extreme gas pressure.
  7. The front double buffer tubes are protected by the sealed composite buffer tube casing. This casings are very lightweight and have very low heat conductivity. All I have done is to rearrange the rear buffer tube to the front. The front buffet tubes have half the diameter of any standard buffer tube in order to be fit inside a standard handgaurd/rail system. When the piston get pushed back by the hot gas, it also compress the front buffer tubes simultaneously. The carrier key cup secures the carrier key tightly in place so that the piston rod could push/pull the BCG. Because The carrier key cup tightly secures the carrier key, it may also solved the issue of carrier tilt. This upgrade kit would also provide a custom shorter version of BCG so owners would not have to saw off the excess part of their standard bolt.
  8. My concept was a piston upgrade kit for standard AR. This kit also eliminate the need of having a rear buffer tube.
  9. Thanks. It is not exactly a standard AR. It looks like a specialize designed upper receiver.
  10. How was that modification worked? Where would they put the AK style spring?
  11. You are correct. I basically rearrange the buffer tube to the front and use two smaller buffer tubes so they can be fitted in a handguard/rail system.
  12. Advantages of this piston upgrade kit concept: 1. Same level of complexity as the standard AR gas piston system 2. Zero to Minimum modification required for installing this piston system to any standard AR platforms. 3. The installation of a folding stock on a standard AR is now possible. 4. A custom BCG may be provided so owners would not have to saw off the last part of their standard BCG.
  13. I could improve the concept with the following: 1. Re-position the upper valve much closer to the gas tube. This would help the entire BCG + BCP get pushed backward sooner. 2. Re-position the lower valve much closer to the returning gas. This would help pushing the BCG + BCP forward sooner. 3. Shorten the path require for the gas to travel through the entire gas channel. This should help improve the condition once the bullet leave the barrel and the pressure begin to drop. As the diagram #3 illustrated, the upper valve should remain open until the lower valve returns at the original position. With the above improvements, would you all think there would be enough gas pressure to push the lower valve (BCG + BCP) return to the original position?
  14. CQB Multi-Dimensional Targeting System Composite Free Floating Rails
  15. brigadier@ have you checked out some of my recent ideas like composite free floating rail and multi-dimensional targeting system? About the first circular piston system, I am pretty sure the dish could be furthered miniaturized. It really depends on the size and the location of the piston dish, further refinement should be able to completely conceal the dish.
  16. You probably right about the gas pressure. I was trying to see if it is possible to utilize the same blow back gas for the entire reciprocating cycle. It could work if the gas pressure last long enough, but this is still a more complex concept. Let me think about this...
  17. The conceptual diagram is quite self-explanatory. Advantage of this concept: 1. Utilize the same blow back gas for the entire reciprocating shell extraction and shell feeding cycle. 2. Require less materials to construct. 3. More simple design. 4. Majority of the gas vented through the exhaust port. Is this concept workable? Do you think this concept is more efficient?
  18. Thanks for paying attention to my diagram. It would take too long to work out the details. I was just trying to illustrate a concept, nothing more. This is my initial conceptual diagram. My idea was inspired by pistons internal combustion engines and steam powered locomotion. I was hoping to replace the standard AR reciprocating shell extraction and shell feeding motions with a circular motion induced by the piston dish. I was hoping the circular motion would introduce less recoil than the conventional reciprocating motions. To answer your question, I could use a dual pistons system where each piston regulates one end of the movement. However this would increase the complexity of my concept when there are already plenty of simpler designs in the market. This is a dead end for me and I need to rethink another completely different concept. A solution looking for a problem is never a good sign, a solution like that would be used for proof of concept at best.
  19. It would take too much time to come up a workable design. This is just my draft conceptual diagram. I want to know if the concept sounds.
  20. There are two key features I would like to point out. 1. Thumb Screw Pressure Adjustor for different barrel length or suppressor setup. The thumb screw simply increase or decrease the internal blow back gas pressure for the appropriate operation. 2. Composite Piston Dish pushes the bolt carrier group for shell extraction and feeds magazine bullet to the chamber. It completes one operation cycle without the need of buffer tube. This feature helps reduce weight and allows the attachment of folding stock. 3. All key Piston + push arms components are made with heat resistance light weight composite materials. 4. Hopefully the reduction of recoil would be able to achieved by the absent of buffer spring
  21. This is the most effective corner sighting system I have seen so far. It has a clearly defined role and it is not designed to replace any existing targeting system. This is also a drawback because it is not design as a corner targeting system, it is a corner sighting system only. As a result of this limitation, this sighting system is effective only within extreme close quarter distance, anything beyond 50+ yards would be difficult to zero on the target.
  22. The setup you mention would have the best chance to achieve durability. The majority of the electronic are mounted on the helmet HUD and only the viewfinder would be mounted on the rifle. However there are two potential issues: Issue #1 ------------- I imagine this helmet HUD would require a fair amount of training and getting used to, before the helmet HUD could be used effectively and could achieved quick target acquisition at various viewing angles. The challenge is mostly from the big sighting distances between the eyes positions and the image taken from the rifle. I just don't know if human brain is fast enough to adapt to this differences... Issue #2 ---------- I can see military and law enforcement would apply your helmet HUD setup, but for the civilian markets where helmet is an optional equipment, The HUD should be flexibly enough to be mounted on the rifle, instead of the helmet.
  23. Samson AngleSight Review of this product http://www.militarymorons.com/weapons/ar.o...3.html#accutact The obvious advantages of the AngleSight design are simple, robust, shockproof and require no external power. However the limitation is also because it is a simple design: You have no control of how much light go into each port when looking through a dark/shade area through the rear port. Another drawback is the field of view is rather limited. It would seems a more complex solution is needed to address these issues. One of the solution is integrating electronic and additional lens to balance the lights into these two ports. But I would not know how to address the limited field of view problem. Another solution (my first post) is to utilize 100% electronic imaging system (with real time image enhancing capability and may be even high speed recording), should be able to address these issue. However the power requirement and durability of such a device would need further thoughts and examinations to better understand the problem. Perhaps the power source could be concealed in a rifle stock.... I still think zero manual manipulation is an important requirement in a CQB where every microsecond count. This feature could be easily implemented by the proposed electronic imaging system. The possibility of developing a new style of gun fighting This device would allow a new gun fighting style that previous would not be possible. Imagine continuous zeroing on target while viewing angle rapidly changing, then one could practice on targets shooting continuously while quickly moving behind a cover in the shortest amount of time.
  24. Corner shot is a specifically design weapon just for this purpose. I am seeking a similar accessory that could be easily adapt to any conventional rifle.
