It looks like ASTKilo23 had some real fun reviewing the Echo1 Spectre RDP AEG... "Echo 1 recently added this interesting little Airsoft gun to their collection. The RDP rapid deploy pistol, is super short, quite light weight, and packs a snappy punch. At just about a foot long, it is easy to carry as a sidearm and uses a V3-style gearbox for easy upgrading."
