First off, I am not new to NFA firearms, and I know all the joys of getting them.

My question is, if I was to buy a NIB Colt M16 from pre 1986.  Would I have to keep the gun fully assembled as it is?  OR could I actually remove the fully automatic part of it that is registered, and put it in one of my newer AR15s?  This way, I would preserve the originality and quality of the original Colt M16, while getting to have a full auto gun in a new AR-15 package.  I own suppressors and SBRs, but the full auto area is something that I am looking to get into, but do not know much about yet.  I will only be able to afford to do this to two guns b/c of the insane prices.  Looking at doing it to one of my AKs and one of my ARs...if it is legal of course.

Thanks,
Mike

For what you propose, you're going to want a registered drop in auto sear instead of a registered M16.

The lower receiver is the "full-auto" part of the NIB Colt M16.

So if you want to switch uppers, stocks and grips.  Fine

Want to take out the FCG, drill hole for sear in an AR15 lower and install said FCG.  ILLEGAL!

Of course.  Sorry I didn't put much thought into it.  So if I use just the lower and build on it, that is perfectly legal.  Also repairing the lower parts as they wear out is also legal?  That's not bad at all.  Thanks,  Mike

Yes, BUT even with that, modifying a new gun to accept it would be illegal correct?

The drop in sears do not require modification to the lower to use. Since the sear itself is the registered part it can be used in multiple guns without any legal problem.

Interesting.  So I would have to find a registered drop in sear?  I couldn't just buy a complete pre1986 Colt and take the sear out and register that part?  Sorry for my questions, just prefer to make sure of the legalities before I start anything.  Also, it's easy to find registered full M-16s for sale.  I have yet to see just a sear for sale.  Thanks for the help.

Found this online.  So this is the part I need?  I assume it's around $10k or so?

Go read up on the sticky in the m-16 forum... Everything you've asked is covered there.

As far as your current AK's go, FA is not an option unless you are a manufacturer. The only transferable AK sears are married to receivers. They can't be removed and put into another gun.
7/29/2011 6:10:24 PM EDT
[#11]
Drop in sears aren't truly "drop in."    They have to be calibrated to each gun so switching uppers or from gun to gun is difficult.

Ok, so let me see if I get this strait...

AR-15-

Buy full auto sear, have it professionally installed in one of my current AR-15s.  As gun parts wear out, I can replace them all, except once the auto sear wears out it can not be replaced, but perhaps repaired?

AK-47-

Buy a $15,000+ full auto AK-47.  Modify to whatever I want.  As parts wear out, I can replace and fix ALL of them?

Let me know if I get this all strait.  Man I wish that ban wasn't in place.

Thanks for your patience everyone.

You don't need to have it professionally installed. You need to do it yourself, but it will need some fine-tuning. RDIAS are not the same as factory sears –– they are a different design. It's almost impossible to wear one out. Figure $14,000 or so for the RDIAS. The host AR15 may wear, and if so, you can replace it with another AR15.

Alternatively, like the AK below, you can buy a registered full-auto AR receiver or a factory M16. Cost will be the same as the cost of an RDIAS, but it does not need "tuning" with each upper. Expect to pay $10,000 (for a registered reciever) to $14,000 (for a factory Colt M16A1). For reference, I've owned a Colt M16A1 for 17 years now, put more than 50,000 rounds through it, and it's still 100% in-spec. My great-great-great grandchildren may wear it out.


AK-47-

Buy a $15,000+ full auto AK-47.  Modify to whatever I want.  As parts wear out, I can replace and fix ALL of them? Except the receiver, which is the registered part, and thus cannot be replaced.

Thanks a lot.  I guess I'm on the hunt for a sear then.  Know of any for sale?  I'd like to do my SBR suppressed AR-15 first.  Ten figure out  a build for an AK later on down the road before prices get any higher.  Thanks for the help.  Shitty thing is I have 2 Colt A1s passed down to me, but both are semi :(

2 places that are good places to start looking for a RDIAS.
7/29/2011 8:15:01 PM EDT
[#16]
For what it's worth...  the RDIAS's can be finicky when moving between hosts... and don't always just "drop-in" as you would expect. Receiver shelf heights are all different, upper rear takedown pin bosses are different, etc...

I've always preferred using a dedicated registered receiver with all milspec USGI parts in it.

You can always swap out the uppers and retain full reliability and easy parts replacement.

RDIAS trips do break,(seen it firsthand) and no two are alike. They usually need to be made from scratch. Not difficult, but still more of a pain in the ass than dropping in a new USGI sear for $10 or $15.

Not trying to steer you in any particular direction... Only trying to say... do your homework and look at all possible angles before plunking down $10k+ for a toy.

For a RDIAS you are looking at closer to $12k-$14k. Depending on who made it, and if the body is steel or alum.

Meh. Says you. I've had four, and I haven't had to do anything with them to get them to run. I've used them on 10+ lowers, with everything from .22 to a belt fed shrike, can't say I've had any issues that were the sears fault.

When you use them, does it make the gun truley selectable from safe to semi to full?  Or is it just always full?

It is a select-fire. If you use a lightning link, those a GENERALLY only Safe-Auto, but you can modify a burst disconnector to get Safe-Semi-Auto.

Scenario, since it came up:

Assuming you have a registered Colt M16 Serial Number 1111

If, for some reason, you lost that in a boating accident

Could you build a lower up from 80% without any markings, have someone engrave the Colt markings and serial number 1111 and no one would be the wiser unless it somehow ended up in the police's hands after you committed a crime with it?

Even then, how would they know unless they had been tipped off ?  

I KNOW what I'm saying is highly illegal. But how could you possibly not get away with that? I know if I broke/lost my 15,000 legally owned, registered M16 lower receiver I'd for damn sure at least consider it. I'm sure you could find a quality engraver and even if you had to pay someone $5,000 to make it look identical to Colt's markings...you still saved $10,000...

First off, what you propose is illegal.

Secondly, a intelligent person would have his $15k asset insured for loss or theft.

Third, the registered component of a M16 is aluminum. If damaged it can be repaired.

Fourth, while there are some gifted engravers out there, getting one to do something that potentionally could get them put in to jail for 10yrs might be difficult.

Ok, so which exact one do I need to make it select fire.  I'm going to have my Class 3 dealer start looking for one for me, and I want to make sure that I get the exact one I need so the gun will behave just like a real M-16 does, even though it's my modern SBR Suppressed AR-15.  I can not tell you how much I appreciate your help with all of this.  I'm very glad this is a legal option, although about $12,000 lol.

ANY of the three can be select fire.

RLL will require a modified FCG for select fire, will not do burst, and does not work with any known 22 conversion.

Put a WTB add on strum or subguns, you should have no problem getting one.
