Just wanted to clarify some things on this topic 1. I am in no way disappointed in my BM-500mk2, it is a wonderful peice of engineering! 2. It is very very accurate! 3. I have the utmost respect for Martin,Sandra and employees of R.A.W.! 3. I have not contacted Martin because I really do not feel it warrants it!, Looking back I should have not even started this thread, It was just something I noticed when shooting this gun( which I love to do) also I want to thank Mark Buchanan for contacting me and sharing some information,he is very knowledgeable about these air rifles! P.S. the results of these air rifles speak for themselves ENOUGH SAID...
