| Finally got my form 1 back (just slipped past the shutdown). Now I have get the upper. I have a yhm 5.56 phantom and I really would like to get a DD 10.3 mk18 upper but I want to know if I can mount my phantom without rail interference or should I be looking at 10.5 uppers? Any help and or pics would be appreciated. Thanks. |

You need to build it to the specs on your Form 1. What did you specify for barrel length? That's not exactly true, especially for an AR....when will people who don't know the law quit preaching it!! 
The ATF only REQUESTS to be notified of any PERMENANT change. Last time I checked, nothing on an AR is permanent. |

I'll give you a second to take your foot out of your mouth so you can take a big step back and read the thread again. You must build it per the Form 1. Build. If the Form 1 specifies 10" barrel, then you build an SBR with a 10" barrel and do whatever you want after that. |
Looking at this pic (not mine) you may or may not run in to troubles.
It is possible that the back of the can will clear the rail if the spring loaded part will fit inside....not sure if it will though. I know shims are typically a no-no, but maybe you could find a quality machined spacer that would make it work. You could always trim the front of your rail....purists be damned!  I have the same MK18 barrel and YHM can, but I chose a slightly shorter rail.
YHM mount for comparison...

Thanks for the help and pics. I'm tempted to just get the noveske mk 18 10.5 upper and be sure of it fitting and a good barrel. Any of you guys have experience with noveske mk18 uppers? Again, what does your Form 1 say, 10.3 or 10.5? You don't really have this choice in front of you right now. |

Ive built a couple SBR's, never once had anyone inspect them. As long as he can return it to what the form says, or notify them of the change later, I don't see what the big fuss is. I got an older SBR Form 1 that says under barrel length, (less than 16"). Back then, that used to fly, now they want numbers for the registry. An SBR is an SBR....I wouldn't worry much what the original build length said. Rock what u want, and notify them later if u so desire. |

They don't accept non-specific configuration info anymore, but even when they did, your "less than 16 inch" info is 100% truthful and accurate at any barrel length. The whole point here is that you might be in violation by not being truthful and accurate to this Form 1. You signed a perjury statement on the Form 1 attesting to the accuracy of the data you submitted. You are now on record on a public form disregarding this statement. If they ever decide they want to come after you for any reason, then you've given them something to do. You can change it as much as you want after the initial build and you are not required to keep the original configuration, but you are required to build that SBR as it was approved. ETA: I think you are misunderstanding the timeline. He hasn't assembled the SBR yet, it's unbuilt and the Form 1 has not been fulfilled. There is no configuration to "return to" as you mention since he hasn't even acquired the upper yet. But that notion that you need to retain the original configuration is incorrect as well. |

Looks like we need someone with more knowledge to come in and settle this one, I'm still very new to the NFA game but from what I've read on here multiple times I'm siding with SMPrider112. Not to toot my own horn, but the "someone with more knowledge" will be hard to find here. Been doing this a very long time. Don't confuse changing configurations of an existing SBR with the initial assembly of the SBR, they are two very different actions. It's not an interpretation or opinion, it's a fact. You are signing a perjury statement to the accuracy of your information, you do not have a legal option to build whatever configuration you want. You have the option to submit any qualifying configuration, but once you sign and submit, you are legally bound to that configuration for the initial build. Once it's been built per the Form 1, you may then change that configuration as often as you like with no further NFA Branch input needed, but "change" by definition is moving from one configuration to another. We are discussing the creation of the SBR, it's initial assembly. Perjury might be seem like a strong word as it has to be a willful deception to stick, but the motivation to deceive need not be criminal. Getting caught is a separate, entirely practical matter. ETA: To put this in a simpler, more common sense manner, there is a reason you are required to define the SBR you are applying to build. If the contrary were true, then there would be no configuration info needed or asked for on the Form 1. |

You will have no problem running the phantom suppressor with the DD mk18 upper. Works perfectly fine for me. The only thing is getting your flash hider on can be a real pain in the ass. But it works, I have had no issues with mine yet. |

| Thank you all for the help. May I clarify to put minds at ease that I already have a 10.5 upper on another sbr to "build" this one and the mk18 upper will be to swap on both of these sbr lowers. Sorry I didn't post that originally. May I ask how you got that YHM mount on with being so close to the rail? Looks great btw |
| I also have a YHM phantom on my factory DD MK18. You won't be able to use a wrench to tighten your flash hider unless you have a VERY thin wrench. I used a piece of barstock and slid it through two of the slots/ports in the flash hider to tighten mine. Worked great. Sorry I don't have pics handy. |
| Thanks! And I actually used the wrench you need to install the RIS ii rail. I put it though the slots on the flash hider and got it tightened down. Hasn't came loose yet so it must be on pretty good. But like stated above unless you have a really slim wrench you will not be able to get it between the rail and the locking ring on the flash hider. Once installed you and the can locked down on the flash hider it has about and 1/8 inch gap maybe a little smaller, won't have any contact with the rail. The one downside to the yankee hill can is the weight. I think with the can and the rifle loaded I believe it's over 10 pounds with all the crap I have on it. Which is HEAVY! |

When you put in your application, you applied to manufacture the rifle with the specs you put on the form 1. After you have done so, you are free to swap around uppers.
