1] The 20" DA-AR15 barrel....does it take the mid-length gas tube on your site? It would be nice if that info was included on the barrel spec page.
2] Do primers have to be shipped by CanPar, or will Canada Post handle them?
That's all....thanks.

I just bought the 20" DA barrel; it takes a rifle length gas tube, and a 5/8" gas block. It shoots really well, but is 1:12 rifling and is chambered for .223, so 55gr. should be about the upper limit... but I am going to experiment with home loads. Mine runs like a top:Originally Posted by Tengoo
Thanks! I guess I can delete the mid-length tube from my order then. This is another bit of info that would be useful on the barrel spec page...I have to say I get impatient with vendors that seem unable to include important details on a sales webpage...

primers can't be shipped by Canada Post...
They shiped my barrel CanPar and it was reasonable. For what ever reason, I was unable to track the shipment until the day it arrived, but it did not take as long as one would think from BC to Ontario. I think CanPar can ship primers.
site has been updated with the gas tube info
Canada post will not handle any dangerous goods
Thanks
Okay...CanPar it is. Canada Post would have been handier, but no problem.

Are you sure these are {only}.223 Stamped/Chambered? I thought CA sold DA 5.56 rifles? One of the reasons I didnt buy a Newer 10.5. They are only recommend-or stamped' for .223 now-I have a Norinco 20" QC 311 & it is 5.56. If you reload, a 223 {only} chamber may not be a big deal, but usually the deals in buying bulk are the 5.56. I understand the '1/12' likes heavier bullet weight, but there is still allot of 5.56 I wouldn't NOT want to shot through an AR build.

Because Canpar is terrible?
Other than head-space, there should be no reason not to shoot 5.56. A heavier bullet is a bigger bullet; therefore it will have a fuller profile to the ogive, this in turn may result in a head-space issue if the bullet contacts the rifling (head space interference).
Regarding this barrel; I won't know until I check the chamber with 5.56 head-space gauges; Generally, heavier bullets like faster twists; lighter, faster bullets need a slower twist. 1:12 is better suited to lighter bullets; while 1:7 for heavier. Spinning a fast bullet too fast can cause them to disintegrate from centrifugal force: .223 traveling 3250 FPS in a 1:12 barrel = 3250 revolutions per second or 19200 RPM; through a 1:7 barrel it would be spinning at 32914 RPM.
