A Plus Airsoft 6.08mm Nickel Coated Copper Rectifier Inner Barrel for WE / VFC GBB (320mm)

Something that us 'airsofters' have grown accustomed to is that most AEGs are more accurate than GBBs, but given the right opportunity for a GBBR to shine, it'll blast any of those AEGs out of the sky. A Plus Airsoft have come out with a inner barrel for the WE / VFC GBBRs to make them more accurate and powerful than ever before.

Also Fits VFC HK417 GBBR

They come in 5 different lengths. 270, 320, 335, 370, and 410mm length inner barrels.
