You were able to order? I try to check out for a 15" and it says shipping quotes aren't available at this time. I really want to order one before they inevitably go out-of-stock. I'll have it on Friday.

I'm stoked! This 13.5 replaces an old 12.0 Omega X rail. The improvement in feel, balance and enhanced lightness with the MFR XS is dramatic! I'm very pleased with it. |

Yes, it comes with a barrel nut wrench, two allen keys, ( one for the rail screws and another for installing the QD plate ) a complete hardware pack for the MFR XS, ( four rail screws, QD plate assy, BUP, collar and barrel nut ) loctite and instructions. A very complete and well packaged rail set. |

A. I'm glad to see these are finally out.
B. Can some one explain this detail (as opposed to straight vertical cut like every other forearm out there). This is the one detail I really don't like about this series.  Attached FileC. What are the weights on these? (not listed on the product page) D. I would like to see these (and the DDM4 rails) made in 9.5 and 10.75" lengths for SBR/Suppressor builds. You make the MK18/RIS II rail in 9.5" but they are unobtainium and I like the DDM4 rail better anyway |

Since they are making a 13.5" I hope that means a 14.5" barrel version of the V7

Mine should hopefully arrive tomorrow. The weather here in Oregon has been a little hectic, so UPS and FedEx have been having delays. For some reason I couldn't order it with my account, so I checked out the rail as a guest and that worked a charm. Ordered the 15", can't wait to install it.

Does your barrel seem to sit low in the rail? My YHM low profile gas block keeps me from mounting anything on the bottom rail of mine and I'm wondering if it's an error of my installation, or if all the rails exhibit this trait because of how close the 6 oclock rail is to the barrel. Can't even snap in an MLOK Type 2 Rail cover, the gas block gets in the way. |

Can't even snap in an MLOK Type 2 Rail cover, the gas block gets in the way. Can you post some pics? From a side profile and from the muzzle end looking back up the rifle. While there's a tad less room between the the bottom of the gas block and rail, I still have enough room to mount accessories there. The four rail mount screws need to be tightened down correctly, ( basically in a cross pattern ) so that the rail will rest evenly against the collar and of course, the top pic rail is lined up with the upper's rail. After assembly, I view the muzzle end of the rail from the top, ( looking down at the barrel, ) from the left and right sides and from below to ensure it looks close to level, then I view it from the muzzle looking back to again check to see if the barrel is basically centered within the rail. If the barrel looks to be off center when viewed from the muzzle end, it can be adjusted some by loosening the screws some on the side opposite from where the barrel is angled toward and then tightening, ( but don't over tighten ) the screws on the side that the barrel is angled toward. For example, if a barrel appeared to be angled toward the left side of the rail, ( when viewed from the muzzle end ) the upper and lower screws on the right side, ( now with the upper turned and facing away/down range from the shooter ) should be loosened, ( I generally use 1/4 to 1/2 turn increments ) and the two opposite side screws tightened down some more. Once these two screws have been tightened down, slowly tighten down the first two screws that had been loosened. Every time you make one of these adjustments, view the barrel from the muzzle end to see how much its moving and if it's moving in the desired direction. |

No one seemed to mind the front lip on the 15" version. I actually liked it but my DD barrel is slightly shorter than 14.5 so I couldn't keep it so I had it milled off. Other than that reason I would've kept it.

I ended up taking it off, gonna call DD tomorrow and see if I can exchange the rail. I tried tightening and loosening the various screws in multiple patterns and no luck, the rail is tilting up from the barrel nut. It makes me wonder if my barrel nut was cut at a very slight angle, and its translating to a large shift at the muzzle end. The rail is definitely tilting and it's not my brand-new DD barrel's straightness; I laid my Aimpoint PRO mount along the top which is perfectly straight, and there's definitely a sloping effect happening as the mount would not lay flat on the 12 o'clock rail at the joint with the upper receiver rail. |

Talked with Jimmie@DD today, he had helped me out before with a defective stripped upper and barrel, so all the parts I'm using for this upper build are new. Should have a new bolt up plate and collar with some screws coming, hopefully that solves the tilt issue. If not it's gotta be the barrel nut. |

Glad to know that I'm not the only one who doesn't like the front of these. I was considering a Slim Rail for my current build, but don't really want to get into Keymod, since I already have M-Lok. Thought that I would love a Slim Rail in M-Lok. Then, these came out. Don't like the general shape as much (less distinctively DD) and definitely don't like the front. Were I to buy one, especially for a build that I planned on rattle-canning, I might take the whole front back enough to make it flat (a little more than shown by TTC above.)
ETA: You know what it is? It's that it seem gimmicky for a company that is anything but. I'd expect it on a rail from a cheaper, less established brand. |

DD needs to hire an industrial designer.
KAC, Colt, and LMT consistently get this right. Almost everyone else gets this wrong. KAC, Colt, and LMT products look like Eugene Stoner designed the stuff himself. Look at all the American firearms from the 1950s-1960s. AR-15, AR-18, Stoner 63, M60, etc. All have straight lines, evenly spaces holes, symmetric holes on hand guards, with straight angles. |
