I have been trying to research my friends AK and the trade marks dont seem to match the airsoftGI model. Is it possible that the one in airsoftGI is back when redstar was vector arms? I remember reading that Vector arms was changed to Redstar. my receiver reads RED(star)STAR(backwards R) SEM.CA 7.62X39MM S/N ECHO1 9879628 with RED(star)STAR(backwards R) under the charging handle Also inside the receiver in front of the hole for the trigger it has CM.029-01A, it looks like it was engraved into the mold because its raised lettering, more like writing i guess. Pictures will come later if requested, i assume someone must know something. Evike has the same trademarks, Newer updated pictured?
