Take a look at the six new GBBRs from BOLT - these utilise Bolt's MAS system, largely derived from the MWS and are fully compatible with both original Marui and Modify-Tech MWS magazines.

Three of these rifles are fully-licensed Daniel Defense replicas via EMG: the Sultra-compact DDM4 PDW and it's bigger brother, the V7 P, plus one of DD's modern icons...the MK18 RIII.

Our favourite aspect of the MAS system is just how heavily it kicks, notably more than the MWS system that it's based on - definitely up there with some modified rifles we've tested. To withstand the recoil, the receiver and handguards have been built entirely from aluminium.
