Agree with both folks above. The nice thing about a Santa Fe, particularly if you're just using it for target/fun shooting, is that you get the feel of an '03 without the worry of using a genuinely original services issued rifle. I've never heard of any issues with them, aside from as mentioned the case head/gas issue, which although rare, is a hefty recommendation to always wear those shooting glasses.
If you ever tire of'er, let this fellow Arizonian know!
Happy shooting everybody!
