Sarah 15, under 100 pounds and left-handed. Forward ejecting RFB works fine for her even though it tips the scales at 14.2lb fully scoped, BUISed, suppressed and loaded. The balance is far enough back for comfortable hold.
I used this plastic “bottle” from Target Factory to verify 100 yard zero of the 1-4x scope on the RFB. It moves vigorously when hit.
She also does an excellent job with much lighter and even quieter guns.
