MM BK1S Stanag Mag Sleeves

The MM BK1S Stanag Mag Sleeves are a cosmetic-and-functional sleeve that slides over your Zius BK1S/BK2S magazine, giving it the profile of a real Stanag magazine while extending capacity up to 15 rounds. It's a sleeve, not a standalone magazine — you'll need an existing Zius BK1S/BK2S Magazine to fit it onto, so check you've got one before ordering.

Finished in orange, black, yellow, or silver as standard, with other colors available by contacting Monkee Mods directly, it's an easy way to bring a more authentic mag silhouette and extra rounds to a BK1S/BK2S build without buying a completely new magazine — useful if you're already running a few BK1S/BK2S mags and just want more capacity out of each one.
