Unless I'm missing something, the only difference I'm seeing is the midlength upper does not include a carry handle sight, or the side sling swivel. Is there any other difference between the two? They're both midlengths, and it seems like I could pick up the midlength upper, and a carry handle sight (or stand-alone rear sight) for another $115 or so, and still be money ahead (about $50 from what I can tell) over the CAR upper. This is using ADCO's prices.
Can anyone add anything? This is all going for my son's graduation present from high school. He's just a sophomore, but I'm getting it a little at a time. Next year is the lower! Thanks!
