So, I recently purchased a CMMG M4LE upper through the EE. Anyway, I'm just wondering which style bolt carrier I got with it. Below is a pic of the CMMG bolt carrier next to an M16 bolt carrier. The CMMG is on the bottom. Is this your semi-auto carrier or the M16? Took the upper out this weekend and it ran great!

According to their web site, looks like you received a SA BC. http://cmmginc.secure-mall.com/item/Semi-Auto-Bolt-and-Carrier-Assembly-184 |

Yes, that is our da bcg. We tried to keep the mass as much as possible. Posted Via AR15.Com Mobile I assume that's a typo and you meant SA.  I didn't even see that picture on your site! I was looking at your uppers searching for a description of the bcg. It didn't even occur to me to look up the bcg itself. I feel like such a dumb-ass now. Yeah, I was confused because there seemed to be more mass on it than what I expected for a SA but less than a FA carrier. As I said, it ran well and that's really all that matters. Thanks a lot!
