These barrels are cold-hammer forged, which is the same process that real firearm barrels undergo. This process creates a very consistent bore, and PDI states that this gives the barrel a tolerance of +0.002mm. This is currently the highest quality in the Airsoft industry for easily accessible stainless steel barrels.

The material is 304 Stainless Steel. This Steel is harder than most barrels and has superior corrosion resistance. Additionally, PDI barrels are very well known for their straightness and quality control.

This barrel is 6.01, which optimizes air efficiency. Since the 6.01 bore is far tighter than the industry standard 6.08, using high quality and consistently made BB's is of heightened importance. Using misshapen or low quality BB's with a tight bore barrel may cause a compression jam.
