Endow your gas blowback replica with increased effective range and shot consistency with the MEC GBB Hop Up Rubber

This precision moulded upgrade has a slightly narrower inner diameter at the entrance and extra coverage for the top of the barrel open cut area for vastly improved air sealing. Internally, it provides two equal points of contact with the bb resulting in increased effective range and more stable accuracy.
