Gunsmithing HS Precision stock and factory bottom metal fit

[johnsopa]

I bought a 700 stainless ADL during one of Dick's sales last year.

I just bought an HS Precision Pro-Series Sporter Stock and some factory bottom metal.

After I assemble everything, I end up with a small, evenly spaced gap the whole way around between the floor plate and the stock.

I do not have the mag box, spring or follower installed yet so there isn't any type of internal interference.

Do you think I would have better fitment if I asked for a replacement stock or is this par for the course?

Thanks.

Probably par for the course. One thing to check though:

Pull the bolt and make sure the magazine box isn't bound up between the frame of the floor metal and the mortise in the receiver. It needs to have a slight amount of play to ensure that the action/floor metal is registering on the stock and not 'floating' due to the box being too tall or from it not being fully seated inside the two parts.

Good luck.

Thanks Chad. I don't have the magazine box installed yet. So, I think the problem is that the bottom portion of the stock doesn't have enough material (most likely) or that the bottom of the aluminum portion (where the pillars would normally be) aren't milled down enough (less likely since this would be a CNC operation). At least IMHO.

No box means the inlet is shallow compared to your part. This can be easily verified with a pair of calipers. Just measure the floor metal thickness and compare it to the depth of the feature in the stock. Subtract the two and it should be reasonably close to what you have exposed from the bottom of the stock.

Some stocks are narrow with a generous radius as the forend transitions back to the trigger guard area. As a result the "hips" of the floor metal can often be exposed. The only way around this is to either switch stocks are get heavy handed with the body work and actually make the stock wider with less of a radius in the affected area.

Not easy to do.


Based on your photo it appears you just need to bury the part further into the inlet. As you suggested, it means lowering the inlet.

Good luck. Not easy with a dremel/manual mill, but very possible with a CNC provided you have the tool path accurately mirrored to the profile of the floor metal.

Let Chad fix it. It will be fixed right.
