MK1 is the only correct choice.

Well since the Mk1 is for real on the table, I'd like a upper with that rail, but with a 16" barrel. Same barrel/rail length proportions as the GOV Duty upper. I'd take that over the GOV Duty upper I've been asking for.

@GACS 11.7 mk8 or mk16. No mk1 interest.
Actually, just do the mk8 and 16 rails in 11.5-11.8 |

I'd be in on this for sure. 10.5 MK16 rail. 12.5 barrel.
That little barrel exposed makes it feel more business. |

Quote HistoryOriginally Posted By _LandCruiser_: LOL at all these late bloomers asking "what is the MK1?". It's only the best rail ever made. Can you quantify that? You’ll have my interest if its not a scarcity driven Instagram points thing. What makes it better than a Mk8, or the issued Mk16? Or for that matter, KAC URX4, Larue, DD, and Hodge? I have experience with all of those, so a basis of comparison would be nice. Why was it discontinued? |

You can get a “just as gud” rail that will do everything the Mk1 can do at a fraction of the cost. However, the Mk1 is still one of the leaders in craftsmanship and aesthetics - well built, intricately machined and great looking. Geissele discontinued it due to cost. If I were to make an analogy, it is like old school Colt Pythons or pinned & recessed Smith and Wessons compared to modern production revolvers, or a HK P7 compared to current production HK pistols. Much better made and they are still iconic of the brand despite being long gone. |
