Just guessing and could be wrong but to be on the safe side get ready for a rather impressive price tag.
These guys got ruger to buils left hand 450 bushmasters on the m77 and american. They have some listed on gunbroker occasionally. You could reach out and see if they have any in stock
As would be mine. If my southpaw son wants a new public land legal deer rifle am going to buy him a CVA Scout in 450BM.The CVA scout would be my recommendation
Give GunBroker a look if you're willing to buy from an OLV. Best prices I found, but then nobody by me has on in stock OTC.I have been looking at those hard! Thanks for your feedback. It’s probably the route I will go. Might be a Black Friday deal local if I can find em in stock. Thanks.
