Purchased thinking this would fit my Krytac MkII. It did not! I should have read the description before buying. Mags were not used, do not have original packaging, and have a tan skull painted on them by the original owner. Injection molded Zytel polymer shell High tension spring for reliable feeding Adjustable between 30 and 120 rounds Magazine shell designed to offer the user a superior grip Pack of 3 Only comparable with: KWA ERG / AEG 2.5 / AEG 3 AEG rifles
