Here are some small tricks I learned to prepping a synthetic stock with aluminum bedding block. May be old stuff to some, but I'm sure it'll be new to others. Bottom line is that these things come from the manufacturer with the stock material and the finish gooped over areas where you want metal to metal contact. The pics show where to check. This is a B&C stock. I wasn't happy with the checkering that came with it, so I textured it with Marine Tex the same way shown on the RD Precision website. You can see that in the pics too.

This picture shows the tang area after clean up. A little denatured alcohol and fine steel wool took the excess material right off. Before clean up there was an uneven layer of material over where the tang should fit.

The area to the rear and sides of the magazine inlet had excess material gooped over the aluminum as well. The excess prevented me from fitting the Kwik Clip DBM set up. Same procedure, scrub with denatured alcohol and fine steel wool till down to bare metal.

Kwik Clip, you can see why the excess material would prevent a proper fit.

Clean up around action screw holes on the bottom too

Check to see if your barrel still floats, if not sand away till it does. Then torque it back together.

Just a little something to check on and fix with a factory gun with this kind of stock, or when you switch to one of these. I can't imagine having soft composite or layers of paint between your bedding block and bottom of your action is a good thing...but I never would have thought to check until someone taught me...so now I'm passing it along. I would think that if this rifle were to be skim bedded, I'd want to clean up all the excess material as well so the bedding compound stuck directly to the aluminum.
