vipermd, I share your viewpoint.
Regarding milspec. I don't mean to imply that milspec is a bad thing. In my opinion, it is a beginning point of reference for a civilian AR-15 enthusiast.
My opinion:
Everyone is gifted with different talents, background knowledge, and experience. For the 1st time AR-15 buyer who:
- Has little to no experience on the AR-15 platform
- Does not have any close friends with experience on the platform
- Does not have any close friends who can set aside personal opinion and be brand neutral
- Has little to no mechanical aptitude
My opinion and advice is to buy an off the shelf factory complete AR-15 manufactured/assembled by a well known, established brand name. A well established company will have the resources to:
- Support a product warranty
- Support a service policy
- Staff a customer service department
- Staff a repair & diagnostic department
The basics I look for (my opinion): proper staking of the gas key, proper staking of the castle nut, fit of the upper to the lower (wiggle it laterally), M4 feed ramps, mil-spec dimension buffer tube (preference), 5.56 chamber, a chome lined or hot salt bath nitride treated barrel, 1/9 twist rate. The choice of exterior features is up to the buyer's preference and body mechanics.
Regarding red dot optics, I have one personal experience to share. I have astigmatism. As I am quickly approaching 40, my eyes are changing again. I started to perceive a 3MOA LED dot reflex sight to have a blurred slightly starburst pattern. I had to switch to a holographic (laser projected) sight with a 1MOA dot. If at all possible, look through as many AR optics and reticules as you can before buying one.
IF YOU ARE MECHANICALLY INCLINED...
There is no better feeling than to assemble your own AR-15. You can choose every individual component in your rifle. You'll gain the basic knowledge to troubleshoot and repair your rifle becoming self reliant. Go to your FFL, choose a serialized stripped lower and go from there.
If you are even more mechanically inclined, you can buy an 80% lower and mill it out yourself.
