    Damn, I'm spending my money on the SBR stamp and an amazing night vision rig in that case.

    Thanks.

    So if I got the AAC mount perm attached would I have to register it?

    If your barrel length is shorter than 16" with the FH attached then the answer is yes you will have to register it as an SBR.

    According to this page on AAC's site, the MITER mount adds 1.75" of length to your barrel. So it will not get you to 16" with a 12.7" barrel.

    get a lower and get that form 1 sent off now.. it's taking 2-6, sometimes even 8 months for the ATF to return approvals.

    Also is there away to install a DIAS and still use the LWRCi trigger assembly.

    I love LWRCi's triggers and don't want to replace it, but I want it to run full auto, and full auto suppressed.
    Unless LWRC uses M16 FC Components, a Registered DIAS would be useless.

    Question

RDIASs generally go for 10-15 grand.. so that's a spendy way to SBR.
    isnt NFA wonderful?
    Actually, according to the NFA Handbook, Appendix B, Page 140, it is stated that it is necessary to place a M16 FCG in an AR15 to run a RDIAS. Unfortunately the wording is not absolutely clear and can be interpreted in different ways.

    A RDIAS is classified as a machine gun according to the ATF as mentioned in this post. However, the Appendix also states that AR15s with 5 or less M16 parts installed will fire automatically with the manipulation of the selector or the removal of the disconnector. Any weapon that shoots more than one shot is a machine gun according to the NFA.
    So it can easily be interpreted that if you have M16 FCG Parts installed in an AR15 (Unregistered Receiver) it can potentially be classified as an Unregistered Machine Gun by the ATF.
    Another question that comes to mind. Where does it say that it is legal/OK to run a M16 Bolt Carrier in an Unregistered AR15? I have heard stories about a letter the ATF publised stating that certain manufacturers could do so, however I have also been told by a couple of respected individuals who are well versed and knowledgeable FFL/SOTs that unless the letter was written to you or you have the exact firearm listed in the letter that you should not chance it.
    Will a M16 BCG cause an AR15 w/ an AR15 LPK installed to accidentally fire full automatic my manipulation of the selector? I think not, but once again it all comes down to how the ATF/NFA rulings are interpreted.
    There are so many questions that come to mind because the material presents itself in a very vague fashion to me. If anyone could point me to a link that has a copy of a statement/briefing from the ATF about M16 BCs used in AR15s, please let me know.
    For all that I know and being a noob on M4c.net it may be buried somewhere in here.
    Sorry about the short novel and thanks for any clarification or links.

    the 15/16 BCG question has been answered a hundred different ways, a few thousand different times. if you want documentation, my suggestion is to write the ATF.

    as far as "chancing" it... do you not realize that there are probably about a million AR15s with m16 BCGs in this country? is there some misconception that m16 BCGs are rarely used or something? there's no "chancing" it... its common practice.

    furthermore, you do realize that the ATF regulates the manufacture of firearms in this country, no? m16 BCGs come standard in Colt, LMT, Noveske, BCM, and half a dozen or more other commercial guns. They do this because the ATF allows them to, not because the ATF somehow isn't paying attention.

    the only reason the STANDARD bolt carrier group is identified as the "m16" BCG is because Colt came out with a supposedly "AR15" BCG that wouldn't operate an autosear. they did this on their own, along with their big hole uppers, large FCG pins, and shelf blocks, to CYA in the event the firearms industry ever became the target of civil suits. otherwise, the question never would have come up, and all we'd have would be one basic cut of carrier.

    Eh, I know it is "common practice" however the point I was trying to make was where is it written where it says it is "ok?" I don't know what your point is asking me if I realize if the ATF regulates the manufacture of firearms, duh? All I am saying is in the NFA Manual it never says it is ok to do so. All I was asking was if anybody knew of a "published" document from the BATFE that states that it is ok to do so in a non Title 2 Firearm.

    However, the most helpful part you stated was to suggest that I write to the ATF. Actually, the whole purpose of me asking the question I did was to see if another member had already done this. Thanks anyway!

    This doesn't make any sense. Why would you need an RDIAS is you already have FA components? Could you clarify which components are you talking about?
