Yes.
Could not effectively use the standard iron sights on the very nice Yugo Mauser.
Even if combat rifles had not been designed to shoot high at 50 and 100 (+) yards., the design of the front post just didn't "grow" on me.
Obturation: the only reason I didn't like my (16") S&W "AR" very much was because the sight distance, paired with my > undeveloped skills< , doesn't seem to compare with the standard iron sights on my friend's 20" Colt (Green Box) AR from 1985.
And its standard length feel + looks, plus the carry handle and the Colt name seem hard to equal among the AR type.
He would never sell it, but if I had $2,000 to spare I would drop the cash in his lap and watch his response (with my wife's "clearance to proceed direct to the fix").
Ironic for a guy who left Essen Germany when he was about 22 years old..
