I’m in for one.
Gonna shoot 5.56 out of it. Just like you would out of an HK MR223. Gun Jesus talks about it here https://youtu.be/-fmcdaAOkY4 |

Anyone know what rail is on it? From the pics it looks like it is Colt branded and made in USA.

I don't believe it is.
To many differences that I can tell. I studied it some more, you may be right, just modified a bit. |

Edit: Disregard.

Alright so I got one of these rifles and took a look at it.
This is the Pinned and Welded 14.5" gun with the quad rail, not the older 16" one. Its a regular Government Profile barrel with a P&W flash hider that's identical to the one used on the 6920 SOCOM. Overall, a really nice little carbine for the money in my opinion. The Quad Rail is nice, there is zero play and its very lightweight. |

I just measured the overall chamber length of 3 different AR barrels to compare with my 16" and 14.5" 6920-EC barrels.
I wanted to get some idea of the difference in the .223 REM barrel bullet jump as compared to the 5.56 jump. I used the Hornaday OAL gauge with a Hornaday 55gr BTFMJ bullet. Results: 14.5" Colt CR6920-EC: 2.350 .223 REM 16" Colt CR6920-EC: 2.350 .223 REM 16" Colt CR6920: 2.355 5.56 NATO 16" FN: 2.370 5.56 NATO 16" DD: 2.370 5.56 NATO Very little difference between the .223 and 5.56 Colt barrels. I can't tell you what this means as far as shooting 5.56 in the .223 EC rifles. I do know that some of my reloaded 5.56 rounds are hot and I show no over pressure signs after shooting in the EC rifles. |
