PSS 6.03 400mm Precision Barrel for M40A5 Replicas

PSS series precision barrels by LayLax are intended for cooperation with M40A5 replicas. 

LayLax barrels are considered one of the best precision barrels on the market. This is due to the barrels having a low deviation regarding caliber differences on the inside of the barrel and undergoing a rigorous quality assurance. Barrels are made in Japan and are manufactured in a very precise way from stainless steel.

LayLax barrels are also much more even, stable and definitely more straight on the inside than a majority of other products available on the market.

We recommend using precision barrels only with precision BBs for a peak performance.
