Product Description
Despite the understandable misconception of many new to Airsoft, a BB being fired does not (or at least should not anyway) touch the inside of the inner barrel. The air / gas pressure behind a pellet pushes the back of the pellet hard but also slips around the pellet escaping forward through the gap between the inner diameter of the inner barrel and the outer diameter of the BB pellet. This tight flow of air around the pellet prevents it from touching the sides thus a pellet being fired is actually riding down on a cushion of air for minimum friction and maximum acceleration.
A tightbore barrel reduces the inner diameter of the barrel in an attempt to reduce the space between barrel and pellet resulting in an even tighter air flow. This tighter seal against the pressure means that less air / gas can escape so the pressure behind and around the pellet is greater which leads to more efficient transfer of pressure to acceleration as well as exerting a greater trapping force between pellet and barrel for a more stable, straighter acceleration pathway.
6.03mm diameter inner barrel are already tightbore enough for most uses but the 6.01mm model pushes the envelope. Because the size is so incredibly close to the BBs diameter you have to make sure to use the right kind of ammunition, premium brands only. Some brands have size tolerances that vary too much or have average sizes too large such that they would simply jam in the barrel or at least be large enough to scrape the sides as they travel down the barrel which greatly increases wear and tear as well as significantly reducing power and consistency.
So that all said, apologies for the mini essay but some newer or less knowledgeable players need to have that explained. If you want to step up your inner barrel to a tightbore, PDI is a truly the premium brand for top tier modification. In particular, the PDI 6.01mm is probably the best series of premium barrels around. Just make sure you use the right kind of ammo otherwise you will at least negate the advantage of this barrel if not even underperform and possibly damage the performance and / or barrel.
Furthermore, do be sure to pick up the right kind of barrel; PDI makes both 6.03 and 6.01 inner barrels in various different lengths for various different models of weapon so do be sure to pick the right type and length for you.

The warranty does not cover:
- Accidental damage (including magazine feed lips & damage from skirmishing).
- Any routine maintenance required.
- Any faults arising from misuse; this includes use of poor quality bbs, any internal damage caused by jammed BBs, overcharging batteries or using the incorrect battery or charger for the gun.
- Any faults arising from using the wrong gas for temperature conditions, for example Tokyo Marui and other ABS guns must only use 144a gas when ambient temperatures are above 10 Degrees Centigrade. In very hot conditions, i.e 25 degrees C and above, some pistols with metal slides must only use 144a gas (this is because gas pressure is increased with temprature). Every gas gun is different and you must check the gas you are using is correct.
- Any faults arising from overcharging of batteries.
- Any faults arising from repairs / upgrades / maintenance not carried out by us.
- Any products that have been altered or adjusted in any way from their original format (unless the alterations were carried out by our technicians).
- Customised items cannot be returned, this includes painted two toned VCRA compliant guns.
