I had a second gen 516 had the same idea you have, from what I found the lwrc bcg would work with a sig but they run around $200-300. I decided to sell mine and built a BCM middy. Loved the sig but the spare parts are hard to come by.

I don't mind the $$$ so much, not for quality parts anyway...I just don't want to buy something that won't work in it.
OK...it appears the 516 does in fact use a standard bolt, or at least the early ones do...not sure about after the changes were made.
So...if the LWRC carrier is indestructible I should be OK, I know the carrier can be damaged...but if it really is a part that does not generally break...I doubt I'll break it, I'm not a high volume shooter these days because I have to work all the time.
I would still buy a spare carrier though if I could find one...
And in case anybody is wondering why go to the trouble with a proprietary piston AR...its simple...its because I have it, got it at a good price, its accurate, has never failed to feed fire or function in any way, and I really like the lower...seems well made and solid.
My son bought this rifle new the day after he graduated from MCRD Parris Island...and he did put it through its paces for a few days before he left back out for Camp Pendleton, went through about 1,200 rounds of my ammo. He decided to sell it to me after he discovered just how weakly a Marine gets paid...so you see, its got just a little bit of sentimental value...and it is a darn fine AR, the only downside is parts availability.
Sig will warranty it if it breaks, but I have found at least one case of them removing the LWRC carrier from a returned rifle and shipping it back out with one of theirs (the carrier was not the reason for the return)...and it ran fine, BUT...I expect to keep that carrier :)
Truth be told...it will fire way more rounds with an RRA Predator Pursuit upper on it anyway...but I still want the Sig upper in working order and on duty for home defense.
And again...thanks for the help...I may have more questions later.
Ridgerunner,
Please keep us up to date as to what you find (or don't find for that matter).
I have a 516 I just used in a three day carbine 2 class. It ran great. Had a couple FTFeeds mid way through day three, but a little CLP on the bolt & feed area and it was gtg for the remainder of the class.
Anyway, it's only got ~ 2200 rounds through but having a backup bolt/BCG would be nice.
I might call Sig on Tuesday to see what is what.
