The MX5-Pro Series from ICS now carry the B&T approval and Airsoft Megastore gives us an overview of one model... "The ICS B&T BT5 MX5-Pro MS1 RIS is one of the few M5-style airsoft guns that come pre-equipped with a rail system. Thanks to its polymer lower receiver, it's also one of the lightest. However, a stamped steel upper receiver and full metal rail system maintains ruggedness and its ability to withstand any airsoft battle. Thanks to its spacious front handguard, this ICS BT5 RIS can store a variety of batteries, including 7.4V mini stick LiPO batteries.

Unlike other M5-style AEGs from other brands, this ICS airsoft rifle comes with a split gearbox that makes it easy to replace and upgrade its Version 2 components like springs, pistons and gear sets.

As a convenient feature, ICS designed this airsoft MX5 MS1 SMG to include a functional safety tension release, which conveniently decompresses the spring without taking the gun apart. In addition to the external build and included features, this ICS MX5 RIS Submachine Gun AEG comes with two high capacity magazines, giving you an edge over your competition."
