Are there any optics out there with built in hold over reticles for 5.56/.223 out of a 14.5-16 inch barrel for under $150?? Can I get a list (if they exist). Thanks for the help guys.
The Nikon P-223 should be around that price range.
There are a lot of them out there, but the reticles are designed for a barrel of X length, X twist rate and with X ammo. The odds that the BDC will match with your rifle is pretty slim in most cases. It may be somewhat accurate, but you'll need to confirm it and take note of the deviations if it is off significantly.
Any MOA dot or Mil dot reticle would perform the same function as long as you create your own drop chart.
Burris has this reticle in a lot of their optics:
Trijicon ACOGs have.
The list would be huge.
