Hi mate,
My friend bought a Axis in .308 as he was in a similar position to you, just getting back into hunting with a rifle an had a budget to stay within.
He got a Bushnell combo with the rifle, I took it out to the range an shot 1 moa groups at 100m using Rem ammo..... So ticked the box straight away for Accuracy issues.
next was the Heavy trigger which I believe could be changed completely, a spring or gunsmith job....
Then the Scope.... The cross hair plain had moved , or something in there did an it wasn't right, So my mate pulled the scope apart and re aligned it.... screwed it back up an has shot some Cracking Fallow stags with it this year...... so Eff'ed if I know but that $600 combo is doing its thing no frills.
IMO, buying an Axis on a budget is a great thing for a hunting rifle, an spending $300 on a Leupold VX1 atleast gives you good optics for any number of Rifles you own afterward.
