You have mis-read my writing for sure(My first language is not english). I dont know why do you sense something negative or think that I have an attitude. But if I had an attitude I could have left the forum. By the way, do you expect that people will always post positive criticism here? I dont think you do.

Now, don't you think that the above difference between HK94 and MP5 along with the analysis that you have given can be very systematic to identify chopped and converted HK94 ?
