Highlander Airsoft reviews the Limited Edition ICS M4 CXP Sirius "Badger" AEG that comes with the Begadi EFCS and Tienley AEG motor. Here is what Begadi says about it... "The SIRIUS series does not contain any fundamentally new ICS designs, but exteriors from different ICS design lines are used for this series. The focus of the series lies in the technical improvements compared to the standard versions that are otherwise available. Thanks to these improvements, the price level is higher than that of the standard versions (the Tienly motor alone has a market price of EUR 67.9), but these upgrades ensure excellent responsiveness as well as correspondingly high performance and longevity - which is also the claim of this series. Regardless of the special upgrades carried out for the SIRIUS series, ICS has also generally raised the prices so that all newly produced ICS S-AEGs are more expensive on the part of ICS."
