Lots of great suggestions here.
I can't recommend one over another.
But, I do have a Vanguard in 223 that is VERY accurate. However, as mentioned, the trigger wasn't anything to write home about. So, I installed a Rifle Basix trigger, and now have a very fine rifle; 3 shots into less than 1/2" at 100 yards.
If I was buying new today, I would consider every one mentioned on this thread.
Merry Christmas..
