Ohhhh!!! We like this! A custom M655 EBB using the Tokyo Marui M4 NGRS in this video from NextGen Retros. We just hope Tokyo Marui is watching this and decide to do some retro airsoft rifles with the NGRS. This uses the Marui M4 SOPMOD as base gun and uses the following: Custom A1 AEG Upper, Custom G&P Front set, Custom AEG Stock, and Custom 20rd Magazine with Bolt Stop.
