Bolt Airsoft posted on their Facebook page a video showing the prototype Bolt MB5 BRSS AEG being tested. This is probably is the first MP5 AEG that comes with blowback and recoil features. It has been some time now since somebody released a new MP5 airsoft gun and this one should be good for those looking for a CQB AEG that has the BRSS features. No idea yet when this will be released though.
