But not clone correct, soooo...... Why chose a McKay vs a Nodak if the machining is like that? Other note, if taking the time to order a Nodak, or refinishing an 80% to A1 via breceman, one should get a black anodized hardcoat. While original A1 receivers would have had the gray anodize, the A1s involved in the Mk12 program were black. Unless I am missing something here and the A1 receivers were already black from the factory vs Colt gray anodizing? |

I wont even bother with NDS. They are behind in production of basically all ar parts. The whole point of NDS was to have retro items AVAILABLE lol.
I agree go braceman with an 80 and rollmark whatever ya want. He seems to be the best bet. Just dyracoat it black and it will wear nicely (under the paint) |

Your other choice is get Hydramatic markings engraved on a NDS, McKay, or Braceman'd 80% lower. Simpler than doing Colt markings and probably less pushback from the engraver regarding Colt trademark logos, which I hear has become an issue with Ident marking services. |

Can we get a consolidated price guesstimate for buying an 80%, having Braceman engrave/profile, black hardcoat anodize, and then finished by the owner? I'd figure you want the Braceman work and anodizing done before finishing for shipping and law reasons.
In my case I have none of the gear needed to drill an 80% out, but an NDS seems slightly out of reach as well. How about buying an anodized lower and just covering up the areas Braceman does his work on with aluminumblack or some other coating? Obviously it will get rattlecanned afterwards but the textures would be different, right? |

For clones I'd prefer they were already machined, but I think they make an 80 percenter version of this full fence as well don't they? I'd be content with snagging a pair of those and getting a HF drill press. (Unlike the okie ass method I've been using/fucking up 80 percenter with. No hand drills will be seeing my A1 lowers, that's for shizzle. |

Anyone looking for an a1 lower should give Harlan a call at NDS and ask, the black anodized lowers usually have way less of a wait time than the gray/retro anodized. Worth a quick call, my last one was ready in 2-3 weeks.

I did load 2000mr all the way up to 262 velocities without pressure signs, and SD was lower than TAC, but it was way above published max. I did not group it. |

I did load 2000mr all the way up to 262 velocities without pressure signs, and SD was lower than TAC, but it was way above published max. I did not group it.

NDS said 2 months ago :we should do another run of A1's (80) before the end of the year........" PS they also run on the "low side of specs" to make a tighter fit "because customers were complaining that they were too loose". I have bought a half fence M16A1 from them and no uppers fit it without dremeling the upper. they made them like this on purpose. its retarded but they did it FOR the uninformed customers who wanted NO WIGGLE. +1,000,000 for getting an A2 redone by braceman and milling it out for a SPEC A1 with Hydra-matic rollmarks (because who wants a colt? ) |

Want a true Clone to use as ammo to fling poop at heretics? Colt for all mods, Armalite and Diemaco extra points for early uppers. If you aren't going balls out, Colt stamped everything, any good forged, non branded/BSed upper would work. If you are painting then just paint over any branding anyways. |

It is also dirty as shit but I never notice any excessive tarnish. My brass is always fifthly when shooting suppressed. I was able to load to Tac 2800 FPS but did blow some primers. |

Finally. I finally got a rail. Thanks Boltcarrier. I submitted a "notify me" with every place on the internet that sells them. The only email I got for notification was from boltcarrier. Figured $350 was better than the $550 that these will be going for again a week or so.

Ok, for those interested in purchasing the Ops pattern long collars here is the best way to proceed.
Go to www.badgerordnance.com and register under the Dealer Program. Instead of putting a company name in the form use "ARFCOM MK12" instead and the account will be approved. (Note, you do NOT need to provide FFL, business license, etc. Just fill out the basic account info.) From there you'll be able to purchase the Mk12 long collars (P/N 249-32) directly from the website. Any questions just let me know. |

What's the time frame on account approval?
