I found this on bud's today- https://www.budsgunshop.com/catalog/product_info.php/cPath/2084_36_140/products_id/411557709

It's a colt expanse m4 with a 14.5 inch chrome lined 1/7 twist barrel pinned to 16.  I was about to start building an m4 clone, with a 14.5 pinned barrel- but it looks like they just made it easy.  One question though- what parts/quality/assembly difference is there between an expanse m4 with a 14.5 chrome lined 1/7 twist barrel and a standard colt 6921?

also anyone know for 100% sure whether the roll marks are still standard colt 'm4 carbine' like the current 6920 rollmark?

There was a resent thread about the Colt Expanse parts not being the same spec. as the original Colt parts.
Mainly the BCG , upper, charging handle, and a few other parts.
All those listed wouldn't concern me, other than the BCG.

If these are the ones I am thinking of, they have the Colt SOCOM CLd bbls.

Colt also released ~300 6920s with these bbls.

6920HBPW I believe.

Eta:  

Rollmark on lower should be the same as 6920s.

Lpk may differ, mainly the hammer and possibly the bolt catch.

Upper receiver probably not C marked.

Bcg may /may  not be C marked.

Lots of threads in Industry forum for Colt on Expanses.


I have a SOCOM bbl, it's shoots great. Wish I bought 2.

Ordered the Black Matte Anodized version of the CE2000HB Thursday.

$681.53, including TAX, Title, & FEES...

Bud's did not have that version, & the version the OP referenced would have been $663.75.
