Just got some of these in. Looks to be a quality barrel. Am going to try and get some groups out of it shortly to see how she does.

Grant,
I saw one else post theirs on TOS with a FSB mounted. Will you be selling these barrels or are they for custom builds?
We will be selling the barrels stripped and in custom uppers.

Hopefully this means that Daniel Defense will be selling a factory SBR configuration in the future.
PT - there’s no way they’re not imo.
Grant - can’t wait to see pictures of the first one with the Mk18 RIS-II rail!
Are these the CHF ones?
Word I got from DD is that all their 10.3" barrels are CHF.
I took a gander at your website but I didn’t see them for sale. When’re they going up for sale?
Thanks!
Yes.

If you want one of these, just give us a call as we have some.

Grant, can you PM me a price on one of these with FSB?
PM Sent.

Just toying with the thought of SBRing my DDM4…would it be possible to send my upper and have it rebarreled using one of these?
Yes we can.

They need to get jumping onto the MK18 builds for the civilian market. I think it would do well for them, and as they already have the parts on hand, there is no reason not to.
Ahhh, They need to get jumping onto shipping some MK18 RIS II rails. I have a build thats been patiently waiting. 
Is there another company out there that is putting out as many new and exciting products as DD right now?
I agree - a Mk18 factory SBR would do well now.
Spooky
No, not really. BCM and Noveske might be a close second.

Out of curiosity, is there a significant decrease in performance going from 10.5" to 10.3"?
Significant? No. Perhaps a few FPS at most. We’re only talking .2" here…
ETA: What I would be more worried about is suppressor compatibility. You may run into an issue with the bayonet lug on the 10.3 interfering with the can if it reflexes back over the mount at all. I know this is not an issue with the KAC NT4 QDSS…
