Does a Lighting Link work when the AR15 is not vertical?

Friend (who has half dozen HK sears and everthing else is chopped liver ;-) was thinking this is the case.

Paper work got messed up on the Lighting Link from this summer ... so still an option.

I assume you me horizontal. Yes the LL will work reguardless of orientation of the AR15.

I only mention these possibilities because they are as likely to happen as you are to "blow up" an RR beyond repair. I recall a tale of woe posted by someone on rec.guns many years ago. His father had a house fire which totalled the house -- and melted his registered-receiver M16 into an aluminum puddle. A steel RDIAS or RLL would probably have been unaffected, unless they're heat-treated or something. Anyway, just a thought.

yes but with that much money in a gun, its probably in a safe, a damned good one too.

what are the associated costs with a RLL ?

I haven't been able to find any information of where you guys are legally purchasing these items. I've got about $20,000 budgeted, but obviously I'd like to spend as little as posssible to make room for other toys :)

I remember in the 80's and early 90's the BATF's once-a-machinegun-always-a-machinegun rule married the rdias to the receiver once it was installed. You could install the rdias in any receiver, but once it was there that was it. I also believe the once-a-machinegun . . . rule was struck down in a case with Vollmer v. BATF by the DC Circuit in the early 90's. I never heard anything more on the subject since then. Did the BATF give up on enforcing the RDIAS -- Receiver marriage rule?

P.S. I just found this forum and I think it is great.

Can you use a RDIAS or RLL with an AR10 (.308 round)? Has it been done before?

The MGI modular lower has a .308 magwell that is in development. According to Mack at MGI, their .308 system will be full auto compatible. So if you had a RDIAS in their .308 system it would be full auto. Infact MGI has in developement a belt feed modual that will take the place of a magwell. They are supposed to offer belt feed moduals in 5.56X45, 7.62X39, and 7.62X51.

Quaterbore posted a pic of an AR10 DIAS (post sample) and it looked nothing like an RDIAS. Also, Quaterbore was working on getting his RLL to work on an AR10, but I think that didn't work out as well. Hopefully Quarterbore will step in here. However, the MGI modular lower will have a .308 magwell and is compatible with an RDIAS and RLL.

Sorry, I never saw this post before now...

I actually never worked on the LL with the AR-10 much beyond seeing it would be possible. All that it really needs is to have the shelf lowered a little and perhaps modify the rear takedown lug to allow clearance. Then you would need to mill the bottom of the AR-10 carrier to work with the link but the basic geometry looks correct...

I still have photos and details uploaded here:

and

As for the DIAS, that will require quite a bit of work to ise with an AR-10 as the AR-10 rear takedown lug is larger. To make this work with the DIAS you would need to weld the rear takedown pin hole closed, mill the rear lug down to the size of an AR-15 lug, and then redrill everything (at least I am pretty sure the AR-10 rear takedown pin is larger then an AR-15 and that there would not be a lot of meat left if you try to cut an AR-10 lug down to fit aroud the DIAS)

There is a SOT that makes a AR-10 LIGHTNING LINK that looks like a DIAS but when you look at it it is clearly a auto disconector and NOT a auto sear!

Details of this are posted here:

Hope that helps some...

These lowers should be RDIAS and RLL friendly:
EARLY Colt
LAR foundry = LAR, Bushmaster, Ameetech (advertised as compatible), DPMS, CMMG (advertised as compatible), Double Star, Fulton
MMS foundry = Mega (advertised as compatible), GSE, Dalphon, POF, Alexander Arms
Bushmaster lowers without an "L" at the beginning of their serial number are made in-house by Bushmaster and are not DIAS compatible. So says the internet folks, anyway.

There may be more lowers that are compatible, but those are the ones I'm told are safe.

You must repair the broken device. Sear trips, pins, and springs are easy to make/get. I'll accept this, but I'm curious where it's written in the BATFE "laws" that this can't be done. Also, I thought I read in a way older thread about this being done before... or was it something else? Is there anything firearms related that can be re-manufactured and serial number transferred (with the old part being destroyed to avoid duplicates)? Or am I thinking of something like car parts of something completely unrelated?

People get confused by the AW ban (1994-2004), which did allow receiver replacement. The machine gun ban, however, does not.

The reason is the different ways Congress worded the two bans.

--The '94 AW ban said that, effective on October 1994, no more so-called "assault weapons" could be manufactured for civilian ownership. It made no mention whatsoever of the "assault weapons" manufactured prior to that date, so there were no legal restrictions placed on the repair or receiver replacement of preban firearms.

--The '86 MG ban was a flat ban of all machine guns for civilian ownership, regardless of the date of the firearm's manufacture. But the law added a clause that proof of legal ownership of an existing MG prior to May 19, 1986 was an affirmative defense against prosecution. The "legal ownership" part has been interpreted by BATFE and the courts to mean any machine gun listed in the NFA Registry prior to May 19, 1986. And the "affirmative defense" clause means that under the law, all MGs are illegal for civilians -- but you cannot be prosecuted for owning one if it was registered prior to the effective date.

Now, a note about law in the U.S.: There are two bodies of law which govern us, those specifically written by Congress, and administrative law, which is written by government agencies empowered with enforcing the broad laws passed by Congress. Administrative law carries the same weight, and in fact the majority of specific laws governing us were written by agencies, not by Congresscritters. If you don't like an administrative law, you have the option of challenging it in federal court; otherwise, it remains the law of the land.

Among BATFE's administrative findings is that the 1986 ban, in effect, froze the status of machine guns. Thus, they prohibit many modifications. If a registered-receiver AR15 was converted via an unserialed DIAS, you cannot now drill the sear hole to "complete" the receiver. A registered-receiver Uzi which has its blocking bars intact cannot have them cut out now. Registered-receiver HKs cannot be drilled for the push-pin. In all three cases, these modifications would only be to bring the receivers up to spec to match their current Form 1s/4s. Yet doing so is a felony (manufacture and subsequent possession of a new, post-1986 machine gun).

My take: Given that BATFE states that it is a felony to drill one hole in an existing registered receiver that was manufactured and registered prior to May 19, 1986, there is no way they will legally let you replace the entire hunk of metal.

Yes, I know some transferable receivers have been replaced in the past. I wish the best to their owners.

saw one today for 13.5K I would not sell mine for 15K.
