Help!! I posted my S&W 908S for sale on one of my local gun boards for 380.00 figuring I would get tallked down to 325-350.00. The gun is in great condition and only has about 500 rounds through it. A guy sends me a message stating that he would trade me a NIB doublestar AR-15 with a YMH rear site for the 908 and 300 dollars. I have been wanting a AR for some time now but don't know much about them. Does this sound like a good trade to you AR guys?
