Good luck with Manners. I’ve given up on receiving a stock made to the specs I ask for from them. 0 for 2. In addition, in my experience, they require a fair amount of fitting too

I was not a fan of the open grip on the UC that I had. And a 2B barrel was too stout IMO, especially after Manners messed up the inletting and left way too long of a shank in the barrel channel
