If you were looking for an all around, general purpose gun, something like a BCM Mid-length would probably do well. These might shoot well, but they aren't precision target guns as they are built to be durable combat grade guns. That is where you have to define your accuracy requirements well(what you want to do with it) for someone to give good suggestions. If you are looking for a bit more precision, then you might want to move up to a cut stainless barrel.
Something like this for example.
Remember, precision is going to be the repeatability of your system. That means you, the ammo, the weapon, the optic... and will be determined by your group size. Accuracy is based on the ability for you to hit your target. You need a balance of both.
