What type of performance can i expect to get out of a 10.5 inch Ar-15 with a eo-tech/sight? I don't want to be at the range trying to get 1 inch groups all day when the gun is only able to shoot 3 inch groups. It is a Bushmaster XM15E2s with a 1/9 twist H-Bar bar with a 10.5inch barrel it has a free float rail system. Also what is the limitations with a 10.5 inch AR-15 like this?
Also what type of ammo is best to use to achieve maximum performance out of the AR.
