I wasn't sure how easy that would be since I haven't taken the strap off to see how tight the opening would be on a NATO strap. Did you email them to request the pins/lugs with threadlocker?The Zulu doesn’t have the double strap part so fewer rings. Charging with either should not present a problem since you can just pull a loop in it to fit the charger, provided you’re using the stock charger. I personally hate those straps enough to prefer the risk of loss over one.
