While wasting time looking at various websites, I ran across the Colt CR6921-EPR on Atlantic Firearms website.  The odd thing is that nobody else has them available for sale and they're significantly less than the CR6920-EPR's that are for sale on Atlantic's website and elsewhere, $950 + $30 for shipping to be exact.  The barrel is 14.5" but has a pinned and welded flash hider so that it's not an SBR.  Youtube and the rest of the internet yield pretty much zero information.  It seems like a decent configuration for the price.  Any thoughts on why it seems to be so obscure?

The CR series of firearms has been renamed/changed. This change affects models such as the CR6920, CR6933, CR6940, CR6960, etc. The CR SKU has been changed back to LE. Be advised that although the SKU has changed back to LE, you will still see CR serial number prefixes.

The 'New' LE SKU products have the following changes:

1. The 4-position receiver extension has been replaced by a 6-position receiver extension
2. The generic 'Carbine' marking on the magazine well has been replaced by the return of the "M4 Carbine" marking.

If you are buying a CR6921-EPR, be sure to have the shop verify that the flash hider is indeed pinned and welded. That is not a normal feature on the CR6921-EPR but the commercial side may have done a special run for them.

Holler if you have any additional questions.

Thanks for that.  They're now out of stock.  I'm glad that I didn't hesitate.  Interestingly, Atlantic had five on Friday, but no one else did.  Now Vizard's Gun & Ammo has five at $1,353 each.

I picked it up and it looks good.  It's well balanced.




Having an M4 profiled barrel under the handguard seems kind of odd, but I guess they do that due to the economies of scale of making M4 barrels.

OP - Does this rifle have the thicker SOCOM M4 barrel or standard M4 profile?  Looks good !
Thanks

Standard M4 and if mine is pin and welded, I'll eat my hat.

I'm going out to the shop and see if I can remove the flash hider.

Not good.

Flash hider came right off, so mine is definitely not pin and welded.

I also measured the barrel length from bolt face to the edge of the A2 flash hider and it measured 15 3/4".

I have a call into Atlantic.

The advertisement  shows what looks like an extended A2 FH.

Mine is a standard A2 FH.

If your firearm was advertised as a pinned/welded firearm. It should have an extended A2 flash hider.

What model number/serial number does your box label show?

They are a pretty decent rifle.
