I have a lot of experience with M 16A2 from 8 yrs in the Marine Corps and have never found this type of rifle hard to shot. With that being said I did quite a bit of shooting in Division matches so I have always found the M16 easy to shoot and to diagnose where the problem of a missed shot came from (always me). I am getting ready to order my first custom gun and my two final choices are a GAP 10 in 6.5 creedmore or go with the GAP M40A3. I have typically been a bolt gun guy and would love to have a M40 yet I am really excited about a gas gun with 3/4 moa guarantee and groups as good as 3/8s. I have read forum after forum of people warning that the GAP and AR 10s as a whole are hard to shoot and maintain accuracy. Where is this coming from? People not used to shooting service rifles or does the system change as the caliber increases (I have a hard time believing this), again all my experience with ar platforms is in 5.56 and I really don't want to order a 4k rifle then not hold the accuracy that is achievable with a bolt gun. Thanks for the heads up and appreciate your feedback as this forum is generally known as the GAP encyclopedia in terms of all things GA precision.
