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: STEEL - Offers a full 10% increase in tensile and compression strength over un-reinforced bedding; requires metal working tools for trimming and shaping and is heavier than aluminum; STAINLESS STEEL - All the attributes of steel particles but with a medium gray finish and no fear of rust formation on surface of bedding.
