Tikka stock with CTR magwell cut, are there any drop in LA bottom metal/mag options?

[boomfab]

I have a Manners Tikka stock with inlet for the CTR bottom metal. I wanted to build a 7mm PRC on it and will need longer mags (AW?)

Is there a bottom metal that available for the CTR inlet with some sort of LA type mag?

I’m pretty sure with the CTR mag length you’re stuck to short action.
