I was working away today when my local gun dealer called and informed me that his distributor had a 6940 on hold. He also said the 6920 Socom was available. Being busy I quickly said order me both of them. The 6920 socom I'm familiar with however I know very little of the 6940 other then the monolithic upper. My questions are, what rear sight comes on the 6940? I have read opinions that the 6940P is superior being piston driven but others say piston guns are a solution, where there was no problem. Did I make the right choice or should I be looking for the 6940p? Finally is the accuracy that much better on the 6940 or will it be comparable to say , my 6920 mp-b?
