Since the ban I have had to get 2 uppers headspaced and check on a problem with my Bushy bolt not locking back, I met Dave Pruett and his staff at GunDoc. I spoke to him at odd's length and he said it has been a crazy AR-15 week, I found out my Bushy magwell was a bit longer than my Colt's magwell, therefore it caused the play with the mag in the well and allowed the bolt catch to slip under the mag follower. All this measured with a micrometer, I was impressed. I am going to have to find out which mags work in my "problem bushy". All in all it was the first gunsmith that I was out in less than an hour, he runs a first class operation. On his wall there are trophies form competitions all over the world along with pics of legends of shooting like Rob Leatham. There is no weapon he will not work on, he knows his business.....
