G'day gents,

In the recent black friday sale I picked up an MDT LSS for my Ruger Scout. I've ran into a couple of issues with fitment and I am wondering if anyone here has dealt with the same thing.

The first shouldn't be hard to fix. This protrusion on the action makes contact with the recess in the chassis, preventing correct bedding of the front of the action.

The second issue is with the tang. The bedding area in the chassis is about 1/16" too low. I suppose this could be brought up with some devcon?

MDT has been quite good to deal with, however have been unable to correct the problem. They said their test rifle seems to fit their product correctly. The offered a full refund, but I'd really like to make this work!

thanks
 
Is that little lug at the front of the receiver keeping the action from seating? Once that is corrected, will the tang seat a bit deeper? Does it rock at present?

I was hoping so but as it is, the contact points are the little lug at the front, and the bottom flats of the receiver at the back of the magwell. So it rocks forward on the lug as well as backwards on the flats. Pushing the tang in by hand lifts the little lug away from the recess.
 
Question, if I can word this appropriately.

If the mating surfaces of the magwell sides (receiver and chassis) are seated flush along their length, is the tang or the lug in contact with the chassis? I’m assuming it’s one or the other, or possibly neither, but certainly not both as that is where you are seeing the rocking motion.

I am in the same situation. Bought the LSS for my wife’s Scout during the Black Friday sale. Action is rocking rather than seating. It seems when the magwell surfaces are seated, I can press either the tang or the front deeper, thus raising the opposing end. Making me think something has changed at MDT’s end on their CNC settings. Will be reaching out to them tomorrow. Will advise.

The aft sides of the magwell are the only portions touching the chassis, because of the clearance issue at the front. It sounds like we have the exact same issue. Press the front lug down and the tang lifts up, or press the tang down and the front lifts up- each time rotating from a different point.
 
Sounds close, if not identical. I haven’t tried to slide a feeler gauge anywhere but it appears the sides of my magwell section of the receiver and chassis are willing to sit flat. This puts the front tab in contact with the chassis which shows the identical mark as yours which makes me think adding clearance to the front might not be the solution. Still wrapping my head around this while fighting the flu. Head is not cooperating.

I’ve emailed MDT, will advise what they say back.
 
Okay, emailed back and forth with MDT today. Good bunch there, quick responses and willing to work with me. Rep says they’ve seen this once before (wonder who that might be) where the tab ahead of the magwell hangs lower than they usually see. They are willing to buy the chassis back and cover shipping. My preference is to make the chassis work. Their suggestion then is to make the recess in the chassis, located in front of the magwell, a bit deeper. I’m going to spend some time looking at the fit and confirm this is a solution and if so, give it a try. Stand by, the dremel is coming out this weekend.
 
It's supposed to be drop in. If it's not "dropping in" with a minimal amount of fitting, then it's either the wrong stock, there is something wrong with the stock or there is something wrong with your rifle.

I would send them my rifle and stock to make sure it's the correct stock before I would pull out a dremel, which may not fix your problem anyway.
