No, its not.

What HTM, is forgetting, is that the Browning BAR, is far more accurate than he is capable of shooting it. I have found that this is the case with just about every rifle made.

Some have a defect, that others don't.

Another thing that he has forgotten, is that when there are hundreds of thousands of one particular model on the market (spanning decades of production). There are statistically going to be poorer shooting weapons to be found.

Also, unless he's trying to shoot for competition, hes asking too much of his own abilities to get sub MOA groups consistently.
