Norinco CQ556 M4 thread pitch?

[BabySeal]

Has anybody tried swapping barrels on the new norinco M4s?

I know that the old ones were metric.

Any chance the new upper and barrel nuts have the standard thread?

Walt at ArmsEast might know, try him?

Crap, did Wes get banned again? Guy's spent more time banned than I've got in as a member!

I do believe it is a standard thread on the new M4's......

I have found that it doesn't take all accessories with some gunsmithing or mod involved, likely built on an A1 concept with there own slightly off milspec procedures.

my diemaco rail does not fit... o-well.

Yup sadly a lot of gadgets will out of specs, unless you're an armourer of course.

It comes to the basics, leave it the way you got it.
