I can't seem to find a clear answer but are registered lightning links compatible with SR25s or other ar10 variants? Thanks

I don't know about a RLL but with enough machining people have gotten post sample drop in auto sears to run. The ATF deemed the AR10's as a different platform, so if you put a registered LL in it you would build a post sample, so not useful for most people. For an 02/07 it could be done, but for them why not just drill the AR10 and be done with it? I owned a full auto AR10 before, not really as much fun as one would think.

Compatible or not, ATF considers it illegal.

there is one guy on sub guns / gunbroker who advartises paddles to work with arma lite pattern ar-10, they are taller.... he will also mill carrier/lower for clearnce for your rll if you send it to him

but the word on this site has always been its a diffrent platform so it would be illegal....

HK 91+HK sear or trigger box.  Or even 91-G3 RR conversion.  The RRs haven't shot up in price as fast as the sears.

Already got an HK sear pack on the way and its prepped for a hk21e and mp5s up the ass. Was looking for something a little more modern and lightweight and figured a full auto sr25 ecc would be tits!
Not digging the old school 308s made of wood, but I will check out the bm59. Thanks gents

This would be my SR-25 replacement in the HK world.  Put your sear in a SG-1 F/A set-trigger and you could have some real fun.

I don't see a reason why you couldn't use a RLL in a Colt LE901.  The 901 uses the same fire control geometry, buffer tube and stock, control layout, as well takes a standard AR15 5.56 upper should you wish to.

Ultimately, the LE901 is nothing more than an AR15 with a 308 sized mag well.

If you can use an HK Sear in a HK23e or a DIAS in a AR47, AR45, or MGI Modular lower I don't see how a LE901 is that much different and is ultimately mechanically less different to a stock AR15 than an semi auto HK "E" xport version belt fed is from its 5.56 mag fed variant.

I have personally never seen a letter stating that a RLL cant be used in an AR10 either.  I believe a DIAS is more mechanically problematic in a AR10 due to the bigger rear lug and the sear trip geometry is higher up than an AR15. (and which is easily rememdied on a RLL by using a taller paddle)

Pretty sure the AR10 letter has been posted here

I don't understand why you couldn't?  If when you bought you LL, RDIAS or RR M-16 if you register it in additional calibers, like people do on HK sears and I have seen done on M-16's then why couldn't you?  At that point you have technical issues, which with say a colt 901 would just be the BCG being machine for either a LL or RDIAS, the rest of the FCG parts should just go in as a 901 used AR/M-16 FCG parts.  Why would it be a no-no?

ATF has ruled that an RDIAS or RLL in conjunction with a firearm it was not designed for constitutes a new, post-sample MG. The conversion device remains transferable and usable as designed, but the new combination is itself a new and illegal conversion.

The 901 question has yet to be addressed.

If so why is S.A.B.R.E allowed to be sold?  A M-16 upper for a MAC-10 registered lower is far more out of whack than a RDIAS in a AR-10?

What if I'm Joe, and when I registered my DIAS via Form 1 in 1985, I wrote "drop-in auto sear for AR15 and AR10 style firearms" in the Additional Description field?

What if someone bought that from Joe today?

(Joe designed and made it.)

do they? not sure that word means what you think it means. The shotgun news gun was selling autosears publically for what like 20 years before he got caught up.  wouldn't really call that enforcement

So if it's not 100% it's not enforcement

Better tell Olofson that he didn't really get arrested. The difference is that they know illegals are coming in but many people in our legislative and legal system want them here.

Border guard isn't going to let a bunch of illegals walk right past him just as a ATF agent or most local cops would be happy to cuff you up for shooting a un registered machine gun.

Just because the administration then turns the illegals loose is not the border guards fault.

I really like those designs, the fact it doesn't require any M16 parts is pretty cool.  It's more of an autoconnector than a sear IMO.

Well, it does require an M16 style bolt carrier, as opposed to the SP1 style carrier used by the RLL.

This style of drop-in is in fact an auto connector.  I've made that style trip for some of my DIASes so I could use them in other rifles without having to install an M16 FCG.

I guess I should have mentioned the carrier, these days they are pretty standard though.  Any issues with extra wear on the DIAS body when using them as an auto connector?

Thanks, an 07/02 in another thread had thought they might wear more because of the different angle and increased pressure needed to trip the disco.

There should be less stress, because it's simply releasing the disconnector, as opposed to catching and holding the hammer back like a normal DIAS does.

Not true. The SABRE requires receiver modification.

They is no difference between an AR15 and AR10 using the same RLL.  It's all just personal opinion.

I'm aware of the hole - I have two of the saber556 uppers myself.  For what it's worth, it's the same mod that's been used by "slow fire" conversions in the past, which mounted an AR style telestock to the M10/M11 in the same manner while keeping it 45/9/380 and mag fed through the pistol grip.

If you want a more complete précis on why ATF allowed the sabre but disallowed the beltfed conversions, you'd have to write them and ask.  As you noted, it's just their (ATF's) opinion, although unfortunately as an administrative agency of the executive branch, it is indeed their opinion which matters in this case unless and until a judge says otherwise.
