Sell your rifle. Use the proceeds to buy a short action SAUM action, modify it for the Wyatt's magezine, and build a new rifle exactly like you want, throated to take advantage of the magezine. Better yet make the rifle a Switch Lug so you can easily change calibers. I bought a SAUM action for just that purpose.
P.S. I'll give you 300 bucks for your Remington. (ha Ha) If it was mine, I'd modify it with the Wyatt's box, and rechamber it for a 6.5-.284. (maybe) Us gun nuts are just too *Rule 4 Violation* fickle.
