I intend on building a MK12 spr but don't know who makes a better upper. PRI or BCM? And for me it doesn't have to be a perfect clone.

I own a PRI and I will say they make the better upper. PRI has been working with the MOD 0 since they beginning of the project. PRI also uses Douglas barrels which are known to shoot very tight groups.
All the info you are looking for is here. |

Do you want a Mod 0 or Mod 1? I'm assuming Mod 0 since you mentioned PRI. Don't forget High Caliber Sales as well. They have ties to Crane and the original development of the platform.
I have been on a months long suffer fest of building my own. It can be done and I've saved a few dollars and have a highly correct upper. That said, if it's not that big of deal then PRI or High Caliber can hook you up. Take StampCollector87's advice and get in the MK12 thread. Tons of info, great group of guys, and very helpful. I've found in the MK12 clone game that if you hate your money you'll be fine |

Mod 0 or 1 doesn't meter too much. And I keep seeing a mod H but i can't see a difference between it and the mod 1

That's quite impressive. And I'm the kind guy that doesn't care what other people think I'd rather have my rifle be a little different than the rest. Also what's the ARMS swan sleeve? Also is a B5 systems sopmod stock frowned upon? And what's the diffebetween it and the crane stock?

So what makes a lower "proper"? Just the fact it's a colt or special marking on it?

McKay makes a A1, Nodak which is considered the best makes one, and Brownells now has them that are made for them by Nodak I believe. The A1 lowers have a different profile then the new lowers they have less reinforcement. Here is a picture of my Mod 1 " /> |

The Mk12 Mod 0 and Mod 1 were built at NSW Crane. The "Mod H" or "Mod Holland" was built I believe by Precision Reflex Inc (PRI) or maybe some Army SF armorer for some Group. I don't know how many were built, but not a lot. Some call it a Mk12 because it has a PRI tube and a 12th Model suppressor that the Mk12s use. And that's about where it ends. |

Do you want a Mk12 SPR clone or do you just want a really accurate upper for your AR? Once you answer that then your eventual path and costs will be determined... |

I'm like you, I like to do my own thing. BCM had the upper I wanted, but of coarse it's back ordered. So I went with a LaRue Stealth 18" upper. All of this was before I knew about PRI (don't have time to look through 1500 some odd pages). I couldn't be happier though. That thread has a LOAD of info on it. I get on there quit a bit.

Well I'd like to have a really accurate AR. But I also really like the mk12s. So l could end up with a bastard child of the two. |

Well I'd like to have a really accurate AR. But I also really like the mk12s. So l could end up with a bastard child of the two. I'm going through the same process now. I like the Mk12 looks but, let's face it, an accurate - in both shooting and looks - Mk12 is an expensive project. To me the accuracy of the rifle is more important than sticking to the Mk12 form factor. The OPS Inc / Allen suppressor collar and muzzle brake contribute a huge amount to the looks of the Mk12 but the actual suppressor design is fairly old and the mounting system is inconvenient if you want to mount it on several different rifles due to the need of the step in the barrel profile. Right now I'm leaning towards a KAC LPR or an MSTN custom upper. Just haven't gotten completely serious yet... |
