I have toyed with the idea many times but have always seemed to pass it off when other experience riflemen have cautioned me against it. And their cautions were from personal experience with both military converted scout types as well as more modern set-ups.
The biggest complaint was balance and usefullness of the sights compared to regular conventional set-ups. Just not enough benefit and mostly a recognized degradation of funtion.
So I have never followed through with the concept.....YET! I still will probably end up doing it in some format or another and then join the ranks of the others that end up preferring standard set-ups.
