Posted this on another forum, but wanted to share here as I have been reading a lot here lately. Just wanted to show a few pics of Colt's 6940 and 6940P uppers next to each other. I picked up a 6940P last April, but due to travel I have not gotten a chance to shoot it yet. After handling it though, I must say I fell in love with Colt's monolithic design. It just feels perfectly balanced when I shoulder it. So, I began looking for a regular 6940 upper, and a few months ago found one for sale. I am going to put it on my M4 Sporter lower. The two biggest complaints against the 6940 seem to be the inability to replace barrels, and the short length of the hand guard. Neither of which bother me at all. I really do not use rails too much anyway, and I have plenty of other "home grown" AR's if I want to swap stuff around every month. One of the reasons I like the 6940 series is that I have heard nothing but excellent results in the accuracy department. Some day I will get both of the uppers to the range and see how that goes. All in all I am pretty impressed with how nicely "packaged" the Colt piston seems to be. They did a great job integrating it into the monolithic platform. Hopefully this week I can pick up a scale and compare weights. Thanks for looking http://www.ar15.com/images/smilies/icon_smile_cool.gif
