Our take: As airsoft players ourselves, first and foremost, we HATE running out of BBs during the crucial moments of an engagement/exchange, especially to find out later that running out of BBs or taking the extra 30 seconds to reload cost you and your team the game.
That's why we created the DUAL-CAP magazine package for your M4/M16 airsoft metal gearbox AEG. It effectively DOUBLES your magazine capacity from 300 rounds to 600 rounds! The package includes TWO (x2) metal 300rd high capacity magazines PLUS a metal adjustable magazine clamp to help you keep the two bad boys locked together.
Compatible with Echo 1, JG, ICS, DBoys, G&G, Classic Army and TM M4/M16 AEGs.Good quality and finish.
For 600 rounds of firepower, choose Airsoft Megastore's DUAL-CAP magazine package.
