Finely powdered metals can be added to acraglas gel to boost its tensile and compressive strength and enhance its impact resistance. This feature allows for the duplex bedding of firearms by using reinforced acraglas gel at the recoil lug contact points, while unreinforced acraglas gel or acraglas is used in less stressed areas of the stock. The ratio of atomized metals can be varied from 1 part metal to 4 parts mixed bedding, up to a 1 - 1 ratio of metal to bedding mix.

• Steel provides a 10% enhancement in tensile and compressive strength compared to un-reinforced bedding, necessitates metalworking tools for precision trimming and shaping and is denser than aluminum
