the iron sights are completely useless. I HIGHLY recommend the Ruger Target Grey Frontier. It's even smaller, with a thicker stainless steel barrel and a comparable price, I got mine for around 400 dollars. I put a burris scout scope on it and the combination is unbeatable. 1.25 MOA with 15 dollar a box walmart ammo is the norm, with factory matchgrade it is consistantly sub-moa out past 300 yards. The scope is a bit heavy but screams "quality" and "durable". I'm waiting for them to come out with a similar scope with a fat, simple ballistic recticle so you have some idea as far as ballistic and windage adjustments...
Leupold will install a bunch of different reticles into their own scopes as an after-market option for a very reasonable price, or for your Burris you might look at some of the other outfits like Premier Reticles, I'm pretty sure they do Burris.
Love the Ruger Frontier - as soon as I can find one in .308 it's mine...
