When only the very best will do for your rifle, PDI is one of the most respected names in the industry. PDI produces upgrade parts with a precision few others on the market can match. Production takes place in Japan, where they use advanced techniques such as cold hammer forging of steel to create the most consistent and smooth surfaces possible. We recommend PDI to shooters building a no-compromise rifle.
The legendary PDI precision barrels
A PDI barrel is not just a tube; it is a piece of high-tech engineering:
Cold hammer-forged stainless steel (SUS304): This process makes the steel extremely hard and allows a tolerance down to ±0.002 mm. That gives your BB a completely stable trajectory.
6.01 mm vs. 6.05 mm: PDI is famous for both. 6.01 mm gives you maximum compression and muzzle velocity, while their 6.05 mm barrels are loved by snipers for the stable air cushion that surrounds the BB and gives excellent precision at long range.
Finish: The inside of the barrel is polished to a mirror finish, minimising friction and the build-up of dirt.
Optimising sniper rifles (VSR-10 & Type 96)
PDI specialises in parts for bolt-action rifles:
Trigger units: Their V-trigger systems are famous for handling very strong springs while giving a fast, crisp trigger break.
Cylinder sets: Precision tolerances between piston and cylinder ensure a 100 % airtight seal, which is the key to consistent muzzle velocity.
Hop-up units: PDI's hop-up chambers let you fine-tune your spin with two independent arms, so you can correct even the smallest deviations in the BB's trajectory.
Maintaining your PDI gear
When you work with such fine tolerances, cleanliness is essential to maintain performance:
Barrel cleaning: A PDI barrel must be kept spotless. Use only the finest cloths and cleaning kits from our airsoft cleaning and maintenance collection.
Lubrication: Use only high-quality silicone grease in tiny amounts on your PDI pistons and O-rings to avoid gumming.
Pair with a top bucking: To get the most out of a PDI barrel, pair it with a high-end Maple Leaf hop-up bucking.
