Hello, I have been checking on all of the models of 16" ar15's and would like some opinions.  The Le6910 sounds perfect because is by far the lightest of them all and in owning 6 ar15's, lighter was funner to shoot especially if you add anything like a red dot sight or a Trijicon acog.  Has anybody tried the smith and wesson M&P model ar15''s? They go for $872 and I found a complete LMT for $950. Please weigh in on those 3 and one more thing to thing about. If your going or I'm going to pay $1200 for a Colt Le6920 would it be better to get a higher end ar15 like a Wilson Combat or Knights armament?  I'll be using it for fun and home defence but would like it to keep it's value well which most of the name ones seem to. Any input, pluses or minuses to each rifle would be great. Last thing is could I put one together myself with better parts and end up with a better rifle? Thanks
