I haven't shot or owned one of the "Frontier's", I did purchase a Ruger Compact a few years back for my son. Appears to be pretty much the same rifle except the Compacts integral mounts are on the receiver vice barrel.
I got rid of that rifle. I couldn't get it to shoot under 1" no matter what component I tried. Looked more like a shotgun pattern than a rifle group! Accuracy usually ran about 1.5-2.0" @ 100yds. I traded it, a small .380 pistol and $100 to boot for a Rem M700 Mtn rifle. It shot sub-.5" with the right combo! Both rifle were chambered for .260Rem. JohnnyK.
