Precision 6.05mm precision barrels from PDI are very precise with high tolerances of 1/1000 mm accuracy, which beats 99% of all precision barrels on the market. These are for serious tuners who want the most out of their guns.
This inner barrel has AEG type cuts in the base, so it is not compatible with the original hop-up chamber. Please use the PDI chamber instead, product code: [PDI-4560249631404]
