Jaeger Precision unboxes the Colt N23 CGS GBBR from EMG and CYMA, a compact and niche airsoft rifle based on a shortened M16 design. He explains that he purchased this specific model because its unique, "wacky" look makes it a perfect candidate for an experimental project, unlike his high-end collector rifles which he prefers to keep in their original retro condition.
PTS Syndicate came up with a "legacy" style compact AR AEG that takes its inspiration from the CAR-15 N23 PDW that never came into reality, if stories are to be believed that there was real design. Recoil Web came up with a story on this over a year ago, and they are not sure if it is a real patent application design or somebody just photoshopped it. But Recoil's Dave Merril tried making one based on the patent application.
