From CYMA's Gas System Line, We have their 30 Round Gas Magazine for M4/AR-15 GBBRs.
This Magazine has been designed for CYMA's CGS Range of GBBRs and Tokyo Marui's MWS/MTR M4 GBBRs.
This magazine is constructed from steel and features T8's Enhanced MWS Gas Seal at a 70 degree angle enuring an uninteruppted gas flow from the magazine into the bolt which helps the stability and effectiveness of the replicas operation.
