Atomized (finely powdered) metals can be added to Acraglas Gel to increase both tensile and compression strength, along with higher impact resistance. This feature allows you to duplex-bed guns using reinforced Acraglas Gel where the recoil lug contacts the bedding and un-reinforced Acraglas Gel or Acraglas for the less stressed areas of the stock. Atomized metals can be added in ratios from 1 part metal to 4 parts mixed bedding , up to 1:1 ratio of metal to bedding mix. We offer five atomized metals: ALUMINUM - Very malleable with ­excellent machinability for easy drilling, tapping, shaping
