Will these be offered in gas-piston or just direct impingement?
I know they are two different measurements but the basis I am going on is at http://www.sportsmansguide.com they separate the two as the .223 has a smaller neck and lower pressures...also the cartridge is not as heavy. Also knowing the higher pressure of the 5.56 can produce premature wear on the barrel.
"While very similar in dimensions, the .223 and 5.56 round are different in the pressures that they are loaded for. .223 Remington is typically loaded to handle lower pressure in the cartridge than the 5.56 round. Also, the headspacing (often referred to as the throat of the cartridge, where it narrows down to the bullet seat) on the .223 round is shorter than the headspacing on the 5.56 round which leads to further pressure differences in the chamber of the two rounds.
A rifle that is built to fire a 5.56 round can safely handle the lower pressure of a .223 Remington round. However, a rifle built to handle the .223 cartridge cannot safely fire a 5.56 round as the higher pressures of this round as well as head spacing of the cartridge can create an unsafe situation (the round will not seat properly in the chamber and the pressure will blow out the chamber).
As you might have noticed, 5.56 ammo is becoming harder to come by theses days putting upward pressure on pricing. We are continuing to search for this caliber along with working to supply a good array of ammo at a competitive price across our site. In the meantime, if you are looking for 5.56 ammo, .223 ammo is a great substitute!"
Knowing that a longer bullet will not feed correctly or eject correctly... what I was wondering is the DD rifle chambered to handle the 5.56x45NATO or is it to a .223 Remington?
Makes a world of difference when finding the perfect ammo

We cleared this up 2 Pages ago. They are chambered in .223 not 5.56 as per American export regulations banning/impeding the export of firearms chambered in military designations. This is a true blue .223 chambered barrel custom made for export by DD. This is NOT a .223 Wylde (aka a .223/5.56 hybrid) chambering and SAMMI reccomends AGAINST the use of 5.56 in this chambering. Some people still do.
Frankly, if the difference is going to blow up your gun, I sure as heck wouldn't shoot the "recommended" ammo out of it, because it's not going to stand up to heavy use.
The firearm (according to the video earlier) is certainly engineered to tolerate a heck of a lot of heavy use..

Last time I checked neither Canada or the U.S. was a member of C.I.P. so this info helps us how? The C.I.P. chamber may differ from the SAAMI standard, I don't know, but apparently it's still different from the NATO chamber. C.I.P also requires that every single barrel made to their specs be proof tested in order to ensure that they're safe for the intended ammo. These barrels won't be proofed so they're unproven.
Even if they were proofed, C.I.P. requires the proof rounds to be 25% above max pressure, while this means it meets the pressure requirements for a NATO round, the NATO round itself would be proofed at 25% above that, so to say that C.I.P. considers them to be the same would seem to be incorrect. I'm no expert and when I looked for the C.I.P. info I wasn't able to find very much so I could be mistaken.
I was reading a bit and from what I am seeing is .223 Wylde the same as 5.56 X 45mm as apposed to the slightly shorter .223 Rem?
...save me the didn't you read the entire thread speech cause no, I didn't.
Slightly off-topic but will you guys be getting new stock on DD parts with the rifle shipment? Or possibly sooner? Ive got my eye on some A1.5 sights and QD swivels
"So are we just gonna go in there and kill em?"
"No, I'm gonna ask them some questions... then we're gonna kill em"
What will the twist rate be on these .223 bbl's?? And is the buffer tube commercial or mil-spec??
Im looking at a V5 at the moment. Are these going to be as the picture shows? (including p-mag, foregrip, magpul stock etc)
I want to make sure that spec wise these rifles are going to be exactly as what is advertised on the DD website with the exception of the barrel being .223. And on the topic of the barrels that they will be made using the same process meaning the ONLY difference with these rifles will be the fact that it is chambered in .223 and not 5.56!
