Not sure if they match up or not. Someone has the Sig 516 BCG's for $129 today. I'm thinking CDNN, but I'm not sure that's right.
ETA: Looks like it's $139, I was off by $10. https://www.cdnnsports.com/sig-sauer-516-gen2-complete-bolt-carrier-group.html#.W_xrpsuWx7g |

Thanks for the link but the reason that I'm looking for a replacment bolt carrier is because the upper that I got from SIG has a semi BC in it (when I specifically ordered a FA BC) and after 4 attempts to get it straightened out it doesn't look like I'm going to get a replacement one from them.

Still waiting for SIG to come across with a FA BC for me. My dealer forwarded the pix that I sent comparing a FA BC with the SA BC and they are reviewing them. WTF? Either it is or it isn't! There's a half inch more steel on the FA BC! I even put a ruler in the pix, what do they need... a picture in Braille?!
If I don't have my proper bolt carrier by SHOT Show I'll have to go talk to them in person. I mean really, WTF? The MULE |

FYI, I have successfully run the LWRC carrier in my 516 upper for over 500 rounds (originally bought it to work with my ECHO trigger which also works well in this setup). If Sig doesn't come through for you the LWRC will work.

Excellent information! Can you tell me if your upper is a Gen 1 or Gen2?
Thanks! The MULE |

Excellent!
Have you noticed any peening on the face of the piston or BC striking lug? Thanks! The MULE |

It saw an Adam's arms piston run fine in a 516

My buddy decided he liked the cool looking skeleton Adam's Arms carrier better so he swapped them out. Then he later sold the other rifle. Now his 516 is bastardized. Runs fine. But still.

Not to be a PITA but did all of those swap-outs involve the BC only or the whole BCG?
I'm thinking about problems with headspace, locking lug geometry, cam pin stress and things like that. Thanks! The MULE |

No worries at all, I get it.
I replaced the carrier only, it uses a standard bolt, firing pin, cam pin, and cotter/retaining pin. I took the parts out of the OEM carrier and dropped it into the bolt. |

Excellent info, I am going to go this route since SIG has not responded to any of my e-mail requests for help through their customer (dis)service. When I go to SHOT later this month I'm going to go to their booth and give them an ear full! Thanks again! The MULE BTW, in case you didn't know, your e-mail and IM features are "Off". |

So, just a little update... I talked to SIG at the SHOT Show and they agreed to send me the correct bolt carrier if I sent in my upper for a "repair".
Then the next week when I sent for the return authorization label they said that although I bought the upper from my dealer as a law enforcement individual, they only sold full auto to departments, not individuals. They then offered me a full refund on the upper, but no bolt carrier. I am currently debating that while I price out some LWRC parts. I'm at the point that I may just return the SIG, never to buy SIG again, and go with the full LWRC upper. YMMV The MULE |

Sig can kiss my ass anymore. I worked at an elite dealer in purchasing. my personal 516 blew up cracked the upper receiver and I had two pieces of gun in my hand. I personally spoke to Ron Cohen and the head of their design team about it and was guaranteed they would send me a replacement upper. Over the course of a year I reminded them continuously of it and never received so much as a single replacement part for it.

I have a full auto 516 10.5 and I have the LWRC bolt carrier. It works perfectly. 1000 rounds shot. They are pricey though. I paid 200$ for just the BC.

I believe in giving credit where credit is due so I have to say that SIG "manned up" and worked with my dealer, Ivan at New Frontier Armory in Las Vegas who went above and beyond on my behalf , to come up with an equitable deal on my behalf.
So I picked up a LWRC bolt carrier and put it in the SIG 516 upper where it functioned fine in both semi and full auto modes. The person at SIG knew what my intentions were and made no cautionary squeals of limited liability or voiding warranties so your information of this being a "good swap" of parts appears valid. I appreciate the help of all participants in this thread, you gave me good information. If anything changes I'll post info. Thanks again! The MULE |

Shark arms has colt piston bcg’s for 35$. I emailed Chris and asked if they would work on a 516. He said he would have to check, but never got back to me. Anyone know if they would be compatible?

I have a couple 516 stripped uppers I could let go if you only need to replace just the upper itself. |
