I just purchased a bottom metal and hardened action screws from Mountain Tactical for my T3X. I tried installing the parts on my MESA precision stock and immediately ran into some issues. I will preface this with, the factory bottom plastic fit snugly and the factory action screws fit good although not as much thread engagement as I would have expected. The mountain tactical bottom metal has some slop length wise and seems to be a hair short on the front not the rear. Not sweating it I tried to install the new action screws. The front screw has minimal thread engagement and the rear screw won't engage at all. I verified my recoil lug was properly seated into the action and tried again, no luck. I also noticed the factory and aftermarket bottom metals sit a touch proud, I'm not sure if this is a problem or not (see picture). What the heck is going on here, is this a stock issue or a combination of out of tolerance parts? I reached out to Mountain tactical this morning, I'm hoping they have good customer service. Mesa did include a set of action screws with the stock which are about a thread longer than factory and MT, the rear screw will grab but one thread of engagement is unacceptable IMO.
