Prometheus Barrel vs PDI Barrel vs ZCI Barrel


Prometheus Barrel


This stainless steel barrel combined with the r-hop is the best barrel you can get for the price point. The Prometheus R-hop barrel is our top recommendation for most players. They are manufactured in Japan with very high tolerances, and the barrels come very straight out of the box. They use superior SUS304 steel compared to other barrels on the market. The polished internal bore and r-hop give enhanced range and accuracy to the user. The internal bore has a diameter of 6.03mm, making it an effective tight bore while still remaining practical. In conclusion, we highly recommend this option for most players that are looking for the best range and accuracy upgrade they can get at a reasonable price.


PDI Barrels

PDI manufactures the highest grade quality steel inner barrels you can get on the market and they are famous for it. They are manufactured in Japan, The machining method for PDI Barrels is cold-hammer forging, which is the same process that real firearm barrels undergo.  This process creates the best consistency for your bore. The machining tolerance for the inner barrel is +0.002mm, which means they offer the highest quality tolerance in the entire airsoft industry for inner barrels. PDI Barrels also have the best lapped inner bore surface quality for steel barrels on the market at ~20 microns. The steel material used is SUS304 Stainless Steel, which is the highest quality steel used for inner barrels on the airsoft market. PDI Barrels are also the straightest barrels on the market thanks to their superior machining. PDI Barrels also undergo strict quality control. In conclusion, PDI sought to make the best possible steel barrel on the airsoft consumer market and succeeded. These barrels are highly recommended and are personally used by our technicians. It is also recommended to add-on a lapping service for this barrel, which will give it an inner surface like EdGI.

ZCI Barrels

ZCI has one of the best prices for performance ratios, being able to give a good performance for an affordable price. ZCI Barrels are constructed out of stainless steel and also feature a quality bore surface quality, very good for the price. ZCI Barrels are manufactured in China, which helps to bring costs and prices of ZCI Barrels down. The machining method used for ZCI barrels is Barrel Extrusion, a common method used for most inner barrels for airsoft. The machining tolerance is around +0.02mm – 0.05mm. In conclusion, ZCI stainless steel barrels is the best stainless steel barrel at its price point of around $20-$30 and absolutely recommended by airsoft technicians around the world.
