What's wrong with the oracle ? I have one I bought for the same intent as the op and it's been a great gun. I can punch quarters size groups with it at 100 yards with factory ammo . I curious why you think it's a bad gun ?
I dont own one but have been at the range with guys who own them and they feel fine, inhave heard of out of spec recievers and bolts, misaligned barrels. I prefer chrome lined barrels for long life and cleaning eeez i dont think the oracle can be had with a chrome lined barrel. Not a big deal really unless u shoot hard and fast and neglect it.
They are very sensitive too dirt, i dont even think they have a dust cover on the reciever... Only competition i have ever shot in (did horrid by the way) the guy after me was shooting an oracle and after the second obstacle he was jammed up tight did a field strip and full of sand. I have had my panther covered in mud and sand never had a lock up. I did lock up with steel case ammo but i hear its an issue for many AR's.
Overall nothing wrong with them if u get a good deal and only shoot for fun. But for hunting and competion i would upgrade a bit.
