Guys when starting a mk12 clone is it best to source AEM5 first then upper? I hate the waits on C3 stuff. What's the consensus of the guys with experience waiting?
I've already purchased the FF RAS. |

You might as well. If you know you want it and hate waiting I wouldn't see why you would want to wait even longer to buy it. |

So, how much flak am I going to get if I run a Leupy MK4 3.5-10X40mm M2 illum FDE on my Mod 1? I just sold my M3 illum to a buddy that I built a mod 1 for, for a lot less than I should have, but we were in the Corps together and I helped him out. I was going to run a NF 2.5-10 on it but I have to ditch a rifle I built to fund it so it will be a bit. My AEM5 should clear next month so like it or not you will be seeing pics with semi incorrect glass! On the other end we have been stretching the legs out on them consistently to 600+ every Friday for the last month. Forgot how much I love these little rifles,.

Guns all get Krylon, glass does not, I swap out glass to much to paint it and resell sucks on painted glass you can never quite get all of it off. On the other side I did just pick up a painted NF NXS 3.5-15X50 2 days ago for $900 that was painted so it goes both ways. |

Your collar isn't seated all the way. You're fine with 4.5 rotations, but that's cutting it pretty close on the minimum recommended. Entirely up to you, but I would probably put a shim behind the brake just for a little peace of mind. |

Your problem lies where the inside step is machined inside the collar. Back of collar is up against FSB before the inside step of the collar is up against the barrel step. This can cause concentricity issues with the suppressor since the collar is not completely seated to the barrel step. |

Range report:
My CLE 4/15 mfg Douglas that is 17.75 OAL got 8 turns with Spartanglory11's AEM5. Adco assembled mod 1 with ops brand long collar and one crush washer and 2 shims leaving the brake and the crown timed perfectly. (Confirming the missing length is between the gas port and the step, hence why the long collar doesn't work on the mod 0 when I had the same exact barrel measuring exactly the same. Just FYI if anyone cares.) Of note: Spartanglory11's HCS mod 1 with AE short collar and the same brake timing got 3.75 turns and shot just fine this weeked. No pics of my MK12 from the outing but here's one of my shortaye' (say it like T-pain) (fake PEQ15 alert. Just wanted to see how it looked)

Same stump mine is propped on I think I butted into a somewhat serious conversation when I posted. It was talk,talk,talk, my pictures, talk talk talk. I don't think anyone noticed

I have posted in the past about my HCS barrel when I began to suspect something was not right with it after my aem5 got to my dealer. I was running an OPs brake and collar and a a surefire shim and getting 3 turns on the can. I ended up installing the Allen collar and taking out the shin and just running a crush washer hoping that maybe the ops collar was out of spec or not seating properly. Here is the result.
Barrel has about 2000 rds down the pipe. How it sits with brake and collar 
Can before being threaded on 
Threaded on 
1 and 1/4 turns!!!! How it measures up 
I will drop a rod later to measure barrel length. What do I do my can should clear in a few weeks? Reprofile barrel or collar, or say screw it and get a BA barrel, since my buddies mk12 has 5 full turns on his |

You're missing almost .25" Yes the step on your barrel (or ops shelf as I've heard it called) just needs to be moved back. I agree with Dan. It should measure 2 inches from the center of the taper on the collar to the shoulder of the barrel (before the crush washer) HCS barrels have seemed to have the problem lately. But it's an easy fix unlike other problems we have seen. Just needs to have the shelf moved back on the lathe |

Barrel shoulder to barrel step should be 1 5/8" If you guys are measuring your barrel, do not measure any part of any threads. |

Put the collar back on; make sure it's seated all the way then measure from the middle of the taper on the collar to the shoulder of the barrel (where the threads start)

First off, I apologize for the late reply. I've been out of town on business and away from the computer. Just getting caught up.
I'm sorry to hear about the issues guys are having with the collars. I'm going to look into that today and if there is a tolerance issue we'll take care of it. This isn't the first time I've heard complaints about the gas blocks, and I will say that we hold the extreme tight end of the tolerance specification. If a barrel holds the tight end as well, tolerance stacking will occur. That alone doesn't fix the issue though, so I'm pushing to get the gas blocks loosened up a bit while still staying within the NAVSPEC. The only thing I'll add is c'mon guys... lets act like men here. If you have an issue with something let the company know before you start mudslinging on the internet. Give them a chance to assist and/or correct any mistake before going that route. We're all human and mistakes can happen, including pounding a device on a barrel when it clearly doesn't seem to fit. MILSPEC556, I'd be curious to know what bad news you've heard about our products. Since you didn't mind making the statement, perhaps you wouldn't IM me to elaborate? I'll stay in touch regarding the collars. |
