Redrams9, my XCR seems same with 223/762-39 but I am lucky because mine shoots surplus 76239 very well. Lee Enfield, have a light contour 223 sticking out of the end of one of my XCR's.
Barrel is about 14 mm in thickness, http://mob174.photobucket.com/album...2FD1A5-3983-0000025C9467FD59.jpg?t=1357258587
Under handguard is about the same, it is a very light barrel compared to the "stock" one. I really like it for my coyote/truck gun.
These guns are supposed to have the reliability of the AK platform but in an "AR" style. Does anyone know if these have been through the hoops like the AK, eg- put in water, dirt and other vigorous testing to see if they still perform?
@ tommycanada, thanks, i was thinking that must be the reason. I found another source that confirms what you say on the xcr forum http://www.xcrforum.com/index.php?topic=5604.0.
@ wOnder, strange indeed that your barrel along with my Bushmaster AR are both stamped 5.56 but were able to be imported.
Thanks for the replies
That is because the state department changes their opinion on what is acceptable every day.
