I have the Standard Operator w/20" barrel.With a full mag comes in @ 14.5lbs..Break in??? I just started shooting the damn rifle.Ammo eats everything,but I did have problems with some reloads a bro made up for me.It scuffed the brass in the begenning but that went away.Got over 700 rds.through it.Just added a SSA-E trigger I got on sale.Got nothing bad to say about the 2 stage NM it came with.Extras I had put on were ambi-selec,winter guard trigger guard,and operator collapseable stock.I attached the sling to handguard to isolate barrel harmonics also bipod.There are a few guys here that have RRA.Takes a beatin and keeps on tickin. <thumbsup>
