A completed stock will ship with two (2) 9/16″ pillars. The pillars will need to be trimmed and the stock will need to be pillar bedded to sure proper fit and feeding. This does not apply to stocks ordered with a BDL mini-chassis.
Stocks fitted with a DBM mini-chassis will be shipped with the appropriate magazine, 2 action screws and a chassis packet with specs. Your action screws may need to be trimmed to size depending on your action model.
