So I may be wrong, but the aluminum bedding block replaces the pillars. It should extend down into the holes where your receiver screws go. The stock is built around the bedding block, so it acts similarly to pillars. I checked stocky's website and this is what they have.
"it has the integral aluminum bedding system that is computer designed and CNC machined out of aircraft grade 6061-T6 aluminum. The aluminum block extends through the forearm to add strength and stiffness and incorporates the attachment of the front sling swivel for additional security. An aluminum tail piece also extends from the bedding block through the grip area to add rigidity and to strengthen the stock."
I hope I answered your question. Hopefully JE Customs or shortgrass can weigh in.
