Count me as somewhat disappointed.
This is a kinda-like, takes-some-parts-from, sorta-resembles-an-AR bolt rifle. What would have been neater would have been a bolt action upper that mounts on AR lowers.
Several people have done bolt actions on AR platforms, but most are either custom or very expensive. Why not one that comes in with lower for <$1,000
Initial pundits seem enamored that Ruger is using standard off the shelf AR magazines. The only other part that seems AR compatible is the stock.
One of the most innovative new features is the magazine well. It accepts both AI magazines (which latch on the side) and M110/DPMS/SR25/Magpul magazines which latch behind. I have criticized Ruger before for inventing magazines and making us pay far too much for them but in this rifle they give us more magazine choice than any bolt action rifle that has come before it. The rifle is supplied with two 10-round Magpul PMAG magazines. - See more at: http://www.thefirearmblog.com/blog/2015/07/18/ruger-precision-rifle-high-end-almost-ar/#sthash.gQLh6J7p.dpuf
Why not make all parts, except the upper receiver and BCG, compatible. Provide a gas block block, so that existing AR barrels can be used. Sell two versions; an AR10 version for .308 family and AR15 version for .223 family. For the first couple of months only sell complete rifles, then make barreled uppers available separately. Later in product life start selling the unbarreled uppers with BCG.
That's my two cents.
