That's a good question.

I don't have one of those, if only I needed another AR15

Those were originally factory sbrs, and that serial range puts them in stand mill spec trigger pin era.  Wonder if they gave any left that are still sbrs.

It looks like they have 6933 uppers listed but are out of stock. With the $0 transfer fee for Form 4s, it's too bad they aren't just selling the whole rifle.

What does “double bullets” mean?
You can't stop what's coming. It ain't all waiting on you. That's vanity.

Look to the left and right of the M4 LE marking. You may have to zoom in a bit if you're on a mobile device.

Blue Mountain leaves out of stock items up for a long time.  Much of their stuff that’s OOS has been that way for years.

They last had complete M4LE SBRs about a year ago.

Those lowers were also used on some early 694x carbines that were sold to LE Agencies.

That looks like it’s in great shape.  Congrats.
The M4LE double bullet is my favorite roll mark.

These were/are 6933s. They first came out as SBRs and were advertised as the "Commando." I pre-ordered one and was disappointed to see these markings on the receiver when it arrived. I have since picked up another lower that either was never on the NFA registry or was removed from the registry before resale. No complaints, save for the disappointment in not getting Commando-marked lower. Oh, subsequently I did get a Commando-marked lower and I Form 4-ed it.

I ordered one from the original batch that Howard Block and David Spiwak ordered and split. I was also disappointed that they were not marked COMMANDO. Though I do still love my OG first run ever factory Colt 6933 SBR.

I have one.   I bought a factory 6921 back in 2003 or 2004.

I did hear back from Colt Archives. It was a LE6933 and manufactured in 2011.
