I think you are correct again, from memory the platform actually got heavier from design specs to production. It would be nice if at least the .223 got a reduction in weight, it's a heavy .223 bullpup. Quote HistoryQuoted:

Quote HistoryQuoted: How would that even work? The whole point is the barrel & bolt head are the only changes (right?) which everyone was gaga over for some reason --was it supposed to be cost-effective, or something? The gun's 2000$!-- and a 556 barrel and bolt head are gonna weigh *more* than a 308, all else being equal. So the only options are to accept a substantial weight/size penalty for a smaller cartridge, or use a much lighter profile barrel for a lesser weight but equal size penalty for a smaller cartridge, along with accuracy degradation. I just don't get it; if a company came out with a 5.56 that used all AR10 parts, they'd be laughed out of the room. Now, a 308 that uses pretty much all AR15 parts on the other hand (POF Revolution) offers a legit advantage over prior art as well as growth potential from the newfound modularity. |

I signed up for a long range class in October and plan on taking the MDR. I want to buy a box of a bunch of different ammo and see what groups the best. Any recommendations on what to pick up? So far here is what I'm thinking:
175gr FGMM 130gr barnes ttsx 150gr ttsx 155gr hornady amax 150gr federal fusion 168gr magtech Any other suggestions? While I do want to test the barnes, they're too much to shoot the class with. Edit: Added these to the list so far DT's own 175gr Federal=Vital-Shok 150Gr Nosler Tip 150gr gold dot |

DT originally mentioned they used: DT match, American Eagle and legit military Federal M80 ball...no other ammo was used during its design and release...then the reviews came with the MDR choking...DT blamed us for using cheap ammo...they didn't care for maaaany months...they even said their MDR performs better than Tavors, SCARs, HK and FN (which I called them out on and they deleted that post but thank goodness I qouted them right away on BPF)...they didn't care until inrange complained about it...then...they just applied a ratio of 11% to the gas ports to "fix" it....
Knowing how tight the chamber is...I bet it was blueprinted from their in-house ammo. |

Knowing how tight the chamber is...I bet it was blueprinted from their in-house ammo. I mean, if DT's ammo actually works in their gun, that's a good reason to use it. Why that ammo doesn't overlap with the standard spec enough to be compatible with NATO ball begs some questions, however. Going back to my R51 example; Remington were being cheap & only tested with their house ammo, which had narrow bullet ogives. It worked fine, so they never realized they were making short-chambered garbage that completely lacked a leade into the bore. It truly wasn't an issue until you tried shooting other makers' ammo with fatter bullet profiles (or tried a go gage). Obviously an egregious example and not what's happened with the MDR/DT ammo but the point is the same; something about that gun/ammo combo is at the far edge of spec, hence the common issues. Although, maybe if you defend the gun & company enough from criticism, those issues never manifest? |

For a gun this short, in a position as rigid as prone, the muzzle jumps upward a full 2-3 inches with each shot. I think that may have prompted the brake swap. As short and neutrally-balanced as bullpups are, I can't help but wonder if mounting the moving mass parts lower (think BREN or Garand...or AUG) might improve that aspect of handling. On a conventional layout, that stuff is all so far forward of the stock support, that the effect of its vertical position doesn't change the recoil impulse much, compared to the impact of stock shape. It's painfully obvious with the MDR, that the BCG hitting the rear causes the top-heavy, neutrally-balanced gun to pivot about the pistol grip, exacerbating the effect of recoil. The RDB does it too, but in 5.56 it's of course less of an issue (also the gun simply doesn't cycle anywhere near as hard) |

So my rifle arrived at DT on the 06/20.. I called and talked to the warranty dept. today to see if they had any updates. They said there are 8 rifles ahead of mine and that things were going slower than they would like but faster than they were. They said things should be going faster from now on. I didn't give me a hard timeline but was assured that it will be tested once the revisions are complete with three different types of ammo (PMC, American Eagle, and Malaysian surplus). Hopefully I will have it back soon.

Looks like the 5.56 version is doing pretty well. Time will tell more, but it looks promising.
I still wouldn't touch the .308. I won't be in the market again for a couple of years now so we'll know more about it and the Tavor 308. I wanted the MDR in .308 to be reliable and be ready to run back when I bought my Tavor but it wasn't, so I decided on a 5.56 bullpup option. I'd wanted a .308 first and then get a 5.56. |

Got mine back from getting the bolt carrier issue looked at and had the updates done. Sps300 on setting 2 functions fine with the load I was using. No apparent brass damage. It did short stroke 2-2 or 3-3 with a bit lighter load on that setting. So it's still not as versatile as an Ar. Looks like they replaced the frame rails again, not much play in the carrier now. It had the 2018valve in it when I sent it back. It did not return with it. I sent an email asking for my valve or my $50 back, got an auto-reply. A little pissed about that. I need to send another email.
