My wife has decided to try NRA Highpower. But at 5'4" and 118lbs she has difficulties with the weight of my match rifles. I am thinking of building her an AR15 with the gov't profile barrel, should come in at about 7 lbs. Anyone know the expected accuracy of the chrome lined 1x7 Gov't Profile? Hoping for 1.5 to 2 moa with a float tube.
