From what I have found it is a 700 barrel length is 16.5 chambered in .223 1/9 twist, threaded in 5/8 X 24 . This would be perfect for a build i am putting together to take my wife and daughter with me to the range. Ive looked around but they are sold out everywhere. It is not even listed on Remington`s site. I am looking for what kinda of velocities are people getting out of this setup.
