Norinco receivers are cut to USGI spec from forgings. roll pin for bolt catch and connector pin is different but as far as most everything else, such as receiver threads, ALL M14/M1A/M305 ect use the same threads except for the actual components on the barrel (gas lock and castlenut)
now....
I gots a question?
by heavy barrel..... these are USGI probably made by TRW or SAK? So they are more like the medium profile we are used to from say criterion and krieger profile/contour wise?
Had a few people messaging me asking questions and advice regarding the standard or heavy usgi barrels and if the oprod guide needs to be like the krieger heavy barrel.
my answer was the oprod guides on these kits should be the same as i thought the usgi "heavy barrel" was in the medium profile and all parts are same between the two.
someone can correct me if I wrong though as I have no knowledge on these kits..... just happy to see them!!!
I will post some photos of the heavy barrel in the morning. All op rod guides I have seen have been either hollow or skeletonised stamped GI type.
