wondering who manufactures/distributes LL/RLL's? someone once spoke of keeping dias in seperate place   safety dep. box....same work for LL?

[Cam2, I see that you have started 4 topics about LLs/DIAS. You are bad news. I have requested that your account be locked and your ip banned. Please find another hobbie, the fines and jail time associated with the manufacture of machine guns are VERY severe. You should think about what you are asking. Sorry.]

was just curious, guess we're tongue tied

Any good class 3 dealer should be able to locate one for you.
Also try Knob Creek this spring.
I don't know about the keeping it separate thing though. If I had a DIAS I would just keep it in the gun UNLESS I was taking the gun to a c-3 unfriendly state.  

I'm pretty sure SWD manufactured the only registered links on the market.  I heard that there are as few as 600 RLL's that are transferable.
