Jack DunrossIgnition custom engineering are willing to import the Wyatt extended magazine boxes for Rem 700's. There's some import fees, so it would be cheaper to get a few of them if anyone is interested in getting one too?
The box I've requested is called the baney: https://wyattsoutdoor.com/product/3-100-baney-coal-kit/
This one will give a COAL of 3 1" or 78.74mm, but they have the standard length extensions too that will also work on the clone actions.
Ignition have said that there is 5 "Baney" kits in stock at Wyatt's. They could import 1 kit for $290 or 5 kits for $855 ($171 each) that included delivery to the same place. (For me it would be Beaton Firearms or DC precision in WA.
I'm definitely going to get one, but if anyone wants to jump on board to save some money, let me know.
