Did my first hundred rounds with the 43X today. The serrated trigger needs to go (did not play well with NATO 124gr) but I'm otherwise happy with it -- despite the small grip diameter I feel like I've got pretty good control over the gun under recoil and the sights snapped back onto target pretty easily when shooting at assessment speed. I turned in an 88 on a B8 at 20 yards using the stock sights, which I was pretty happy with given that I haven't shot an iron-sighted gun in four months. Next step is getting it milled.
