Quote HistoryQuoted: They said 4 is the new normal, 2 is suppressed, and 6 is adverse. Called DT warranty, the new parts mentioned in the video are not yet available, and all of the new 6 position gas plugs are either being incorporated into new rifles or sent to people who had requested them earlier. |

Wow, it runs for at least five rounds sequentially. Too many camera cuts to say more than that... other than, hey, that's some seriously inconsistent ejection. That doesn't bode well.
ETA: I stand corrected, the second string was one camera cut. Good. So it runs at least one mag without an issue. This is nothing to celebrate, but if it does that a few dozen times in a row with no problems and with factory M80 ball, good. They may get a few customers with that video, and if they deliver guns which don't work, ouch. We'll see. |

Quote HistoryQuoted: My bad.

They should be getting any new parts to those that already paid good money first, then resume getting new guns out of the door. I reality, they should be getting every gun out there running before producing and selling any more of them. |

Which is a valid point since fixing shit costs money. If it's "new guns go first" or bankruptcy/welshing on the warranty...I'd say this is the less sucky of sucky options.

It appears that one shipment has gone out. Approximately 10 to 20 guns, if the 223 release is anything like the 308 release it'll be a while before the second shipment and a long time before there are regular deliveries to dealers.

So I finally got around to watching the InRange review of the 'fixed' gun. It sounds like DT has corrected the timing issues with a (much) heavier hammer spring? Because I don't see how they could possibly fix the peaky gas-adjustment (either way overdriven with often-torn case rims, or short-stroking) simply by playing with port sizes inside the range that was already not working. There's also no way an extractor change could reduce the amount of operating force needed to yank a case from the chamber. So, either DT is now relying on a hammer spring & larger extractor to absorb the excess velocity from a highly-energetic extraction process, or...wait, that still doesn't make sense because of the short-cycling issue.
I wonder what they actually changed in the InRange gun, for it to function reliably with weaker ammo while also exhibiting less recoil?  It sure as hell wasn't just an extractor & gas plug.
And maybe I'm just stupid, but I still don't understand (and never have) exactly how this gun is so technologically or ergonomically ambitious, or whatever other glowing descriptions I've been hearing about it from the beginning. There have been ambidextrous bullpups before, even 308s. There have been bullpups with similar ergonomics & accuracy already. Caliber-conversions have been demonstrably 'debunked' as a particularly useful feature (users invariably buy more complete guns to house them). The forward-ejection is the *only* unique-ish feature, and even that's been done on other bullpups (though without even the need for swapping it left & right). Besides it looking cool (I guess, that handguard has always been a little whack) why the excitement, apart from it being an ambitious manufacturing/development project for DT (which has not panned out all that well so far)? I initially thought that because it had "DT" on it, it was going to offer exceptional accuracy & trigger along with those other bullpup features, resulting in a "best of both worlds" scenario --that hasn't happened, yet I still hear many praises of DT's supposed accomplishment via the platform.

I watched the video, and I am 100% sure that the gun worked for Ian and Karl, but they only tested it with M80 ball. Did DT actually fix the gun, or just tune it to run with M80 ball? Will it run with other ammunition? Either way, it appears the best way to get customer service, a proper fix, and a quick turnaround from DT is if you have a quarter million followers on youtube and the the fact this got fixed so fast for them was PR damage control.

New MDR Upgrades video from Desert Tech:
https://www.youtube.com/watch?v=xVlsS23TDAA TLDR: They talk about the upgrades mentioned in the InRangeTV video and then a montage of them shooting several different brands of ammo. American Eagle .308 and 7.62x51 IMI Magtech Federal XM80C Tulammo .308 (zinc coated jacket) STG 7.62x51 PPU 7.62x51 7.62x51 Hirtenberger Malaysian L2A2 7.62x51 Korean M80 Ball surplus 7.62x51 BBM BVAC UMC Federal 762D Fiocchi Desert Tech EDIT: Called DT today about getting the new parts, when I asked about keeping the old parts, they mentioned that the widened extractor requires replacement of the case support and changing headspace, so it is not a drop-in upgrade. |

However, since we're all friends here...I was told that they would start in about 4-6 weeks for the barrel/extractor work and a few weeks after that they would have the hammer springs. The barrel and bolt would have to be returned for warranty work, and the customer would have the option to return the fire control group or they could do it themselves with the provided spring. |

I'd advise anyone with one of these things to return it for a full refund if it hasn't worked right and you have the evidence and the paper trail. The crazy thing, is you see people almost every day posting crap about the P320, a gun that had one major malf, which was handled very quickly, and new model put into production without the issues. The guns are not having problems holding together, they aren't having failures to feed, extract, etc, and aren't picky about ammo. This is a $500 gun for a standard model. Yet, here we are, about 4 years in, with a gun that has been nothing but terrible , without any of the benefits that it was sold on. And it's a $2500 gun. And now they want you to wait another 4-6 weeks, and then you have to send it in, in the hopes that maybe, just maybe, you'll get a working gun this time. This whole thing is like taking your car to a parts swapper instead of a mechanic, the difference being, the parts swapper is at best guessing at the issue, doesn't know what's really going on, and just puts on a part that he hopes fixes it, over and over. |

Whilst men are linked together, they easily and speedily communicate the alarm of any evil design. They are enabled to fathom it with common counsel, and to oppose it with united strength. Whereas, when they lie dispersed, without concert, order, or discipline, communication is uncertain, counsel difficult, and resistance impracticable. Where men are not acquainted with each other’s principles, nor experienced in each other’s talents, nor at all practised in their mutual habitudes and dispositions by joint efforts in business; no personal confidence, no friendship, no common interest, subsisting among them; it is evidently impossible that they can act a public part with uniformity, perseverance, or efficacy. In a connection, the most inconsiderable man, by adding to the weight of the whole, has his value, and his use; out of it, the greatest talents are wholly unserviceable to the public. No man, who is not inflamed by vain-glory into enthusiasm, can flatter himself that his single, unsupported, desultory, unsystematic endeavours, are of power to defeat the subtle designs and united cabals of ambitious citizens. When bad men combine, the good must associate; else they will fall, one by one, an unpitied sacrifice in a contemptible struggle.
–Edmund Burke, Thoughts on the Cause of the Present Discontents 82-83 (1770) in: Select Works of Edmund Burke, vol. 1, p. 146 (Liberty Fund ed. 1999). |

Quote HistoryQuoted: Do what they did on the Yugo M76 to 'grow' the gas system but keep the overall package much shorter than a PSL despite being in 8mm Mauser; -Make the piston head long enough to go past the gas port when in battery -Drill a hole in the side of the piston (at a turbulence groove) so it aligns with the port when in battery -Drill a hole in the front of the piston that intersects the side-hole Gas flows through the side of the piston out the front through a longer semi-tortuous path (dropping its pressure, effectively lengthening the path even more) where it fills up the gas cup, and drives the piston rearward. Shortly after the piston moves, the turbulence ring misaligns to the gas port, shutting off additional gas flow (by this point the piston already has enough pressurized gas in front of & inside it to complete the necessary acceleration). The result is a short, quasi-self-adjusting gas system. Oh, the M76 also has a blow-off port in the front of the gas cup, which essentially 'damps' out gas cup pressure spikes as well. Lastly, the gas cup itself is adjustable rather like the MDR, with different size orifices that can be placed between the piston and the port in the gas block. If you put a tit on the end of the piston that initially blocked the blow-off port sort of like the G36, you'd have one of the most sophisticated self-regulating gas piston systems possible. |

If you put a tit on the end of the piston that initially blocked the blow-off port sort of like the G36, you'd have one of the most sophisticated self-regulating gas piston systems possible. But apparently changing an extractor & hammer spring solves all the issues, so there's no need

Quote HistoryQuoted:
Whilst men are linked together, they easily and speedily communicate the alarm of any evil design. They are enabled to fathom it with common counsel, and to oppose it with united strength. Whereas, when they lie dispersed, without concert, order, or discipline, communication is uncertain, counsel difficult, and resistance impracticable. Where men are not acquainted with each other’s principles, nor experienced in each other’s talents, nor at all practised in their mutual habitudes and dispositions by joint efforts in business; no personal confidence, no friendship, no common interest, subsisting among them; it is evidently impossible that they can act a public part with uniformity, perseverance, or efficacy. In a connection, the most inconsiderable man, by adding to the weight of the whole, has his value, and his use; out of it, the greatest talents are wholly unserviceable to the public. No man, who is not inflamed by vain-glory into enthusiasm, can flatter himself that his single, unsupported, desultory, unsystematic endeavours, are of power to defeat the subtle designs and united cabals of ambitious citizens. When bad men combine, the good must associate; else they will fall, one by one, an unpitied sacrifice in a contemptible struggle. –Edmund Burke, Thoughts on the Cause of the Present Discontents 82-83 (1770) in: Select Works of Edmund Burke, vol. 1, p. 146 (Liberty Fund ed. 1999).

So how much $$$ is DT investing in the service department now...because I bet the backlog will be pretty intense on getting the new extractor work done....
In all seriousness...hope all this does fix the MDR's woes...time will tell... |

es tactical ordered and fitted a mdr barrel extension to a 18in bsf barrel with a rifleman length gas system the gas block is moved forward 5 inches so i will have plenty of room to do a long stroke if decided to go that route. i work at a place were i have access to all the milling and cnc lathes i could need to build it . What i need is detailed info on how the m76 gas system works from the little i have seen i believe i can get this to work without interfering with anything else the other system i really like is the pws long stroke if you have the time could you pm me some close up pics with the dimensions of the piston and how it bleeds off and were it bleeds off o and the weight of the bcg mass

Quote HistoryQuoted: I built mine, which is how I learned those things. I'd be amazed if you could adapt it to the MDR; I'm pretty sure it'd require a new gas block, new gas regulator, and new piston. If you're doing all that, you might as well also make the gas system longer (more like other short 308 piston systems like the Galil MAR) since it'd require only a barrel & piston. But apparently changing an extractor & hammer spring solves all the issues, so there's no need |

I will say the M76 was designed to work with a QD suppressor; I'm sure it was a very leaky low-backpressure type, but considering how sensitive AKs usually are to backpressure changes, it's encouraging. 
I will also say, the system seems sensitive to changes in "starting volume" (gas volume in the gas block/piston when in full battery) since making the end-bore larger really drops the operating power. A regulator that simply threads in/out to take up space could be an effective, non-venting/non-obstructing way of controlling piston impulse (of course, there is some risk involved if you can make the gun run too hard) |

I swear this is the only weapon platform in the world where we are talking about introducing commie tech into a $2500 rifle while spending more and more money into it just to see if it improves....
You all have a ton of patience with this crap...

At this point, I want the upgrades only so I can sell my MDR as a “fixed” gun.
