I've recently transitioned from a 1-4 on my 16" AR to a quality 2.5-10. The barrel is a medium contour 5.56 chamber and floated.
With the new optic and my current commercial 77gr selection I'm reliably getting 1.5-2MOA at 600 yards and usually similar results at 100. Part of me suspects that me + the optic exceed the capability of the rifle.
I have a few questions for those more experienced than me:
1. What's a reasonable accuracy expectstion for a gas gun and 5.56 chamber using match ammo?
2. How important is having sub-MOA accuracy when engaging small targets out to 600 yards? I'd call 1-2 MOA a small target.
3. What is the path to greater accuracy? New barrel? Better ammo? What are the recommendations for barrels these days? Hand loading is not an option.
I'm measuring accuracy as 5 and 10 round groups. Sometimes fired from a bench, sometimes prone with a sling and or rest.
Also- I've noticed that my 100 yard groups are frequently less impressive than 200 or 300. Has anyone else seen this before?
