No changes here. I have been well pleased with mine. It hasn't had a hiccup yet, and it shoots right there with my other ARs. The only thing it "needs" is a trigger job, but that is no big deal and can be used just fine as-is for deliberate fire.

I am not in awe of the rear sight, so someday maybe it will be replaced (possibly with Troy night sights front and rear). But overall it is perfectly serviceable and, for the time being, all is well.
