Anyone know of a lefty bolt with a detachable mag, in stainless, comes with a MOA guarantee, is under $1000 and is lightweight? I have a Tikka 308 with optic and sling that's under 8lbs, but my buddy has a Kimber Montana (I think that's it) in 308 that is approx 6.5 lbs. with optic. Kimber doesn't cater to lefties.
