I have 3 of the Predators in 223, 6.5 CM, and 308. Paid $389 OTD each. I'm not gonna say they are 1/2 MOA all day long, but sub 1" groups at 200 are pretty common. I don't even bother shooting them at 100 anymore. I can't recall ever shooting a group over 2" at 200 yards.
I've thought about upgrading to a better looking stock, but anything I'd be interested in is $300 and would be 1/2 lb heavier. They shoot just fine in the stock they come in and if I've got $700 to invest in a Ruger + stock there are better $700 options.
I liked the Marlin X guns better and would have preferred if Ruger had put the RAR barreled action into a stock that was like the Marlin, along with the Marlin's blind magazine. I don't care for detachable magazines on bolt action rifles, don't need the magazine capacity and don't care for a magazine that protrudes below the stock.
The detachable magazine is the key to the accuracy at a budget price. The Ruger uses an action with a solid top that is much stiffer. Plus a massive bolt. The enclosed action requires a detachable magazine, no other way to load it. Plus traditional internal magazines make it harder and more expensive to get extreme accuracy. Not that it can't be done, but it adds to the cost and complexity of the rifle. Using detachable magazines is cheaper and easier to manufacture and eliminates one problem.
It took a while the magazines to grow on me, but once you figure out the advantages they offer and the cost savings I can live with them. Most of them use flush fit 4 round magazines. They do not protrude below the stock and offer no mag capacity advantage. But that is an option on some of them.
I've had 3 RARs and 20 RAR-Ps. Have thought about buying a RAR-Ranch Rifle in 6.5G or 7.62x39, but have never gotten around to it.
I still have 2 of the RARs, one of the 1-8" ROT 22-250s from Whittaker's special limited run and a Cerakoted limited run in 6.5CM.
I still have 16 RAR-Ps in 204, 223(x3), 22-250, 243(x2), 6CM, 25-06, 260(x3), 6.5CM(x3), and 308.
Most of mine have flush fit magazines that don't protrude below the stock, but Ruger seems to be moving away from them and toward the AR-style magazines. Of the 17 different RAR-Ps listed on the Ruger site, 8 come with flush fit magazines and 9 come with AR-style magazines.
I don't know if the detachable magazine is the key to accuracy at a budget price. The conventional blind magazines in the Marlin X guns and Savage 110 family were known for their out of the box accuracy. The Marlins X guns were always budget priced rifles and the Savage 110 family always had a budget prices option somewhere in the line, either branded as a Savage or a Stevens or, in rarer cases, as a house-brand.
I would agree that RAR-Ps have earned a reputation for accuracy, but accuracy is only one aspect to consider when exercising the decision making hierarchy.
I still like the Marlin X guns better and think that they were a superior platform when compared to the Remington 783 that replaced them. But like the old Yamaha motorcycle ads said; "Different strokes for different folks".
